Build a Modular AI Agent with AllToken

This skill helps you create a modular AI agent powered by AllToken — a unified, OpenAI-compatible API with access to leading language, image, and video models behind one endpoint, plus automatic provider fallbacks and cost-effective routing.

Designed to be invoked from Hermes, OpenClaw, Claude Code, Codex CLI, or any other agent runtime that consumes skills.

• Standalone Agent Core — runs independently, extensible via hooks
• OpenAI SDK compatible — change two settings and you're done
• Multi-modal — chat, image (async), video (async) on one key
• Optional Ink TUI — terminal UI cleanly separated from agent logic

Prerequisites

1. Create an AllToken account at https://alltoken.ai.
2. Generate an API key in Settings → API Keys (the key is shown only once — copy it).
3. Top up credits if needed in Settings → Billing.

Security: never commit your API key. Use ALLTOKEN_API_KEY from the environment.

API at a glance

• Base URL: https://api.alltoken.ai/v1
• Auth header: Authorization: Bearer $ALLTOKEN_API_KEY
• Compatibility: OpenAI-compatible — any OpenAI SDK works by overriding base_url/baseURL.
• Coverage:
  • POST /chat/completions — chat (streaming, tool calls, thinking, web search)
  • GET /models — OpenAI-compatible model list
  • POST /images/generations/async + GET /images/generations/{id} — async image generation
  • POST /videos/generations + GET /videos/generations/{id} — async video generation
  • GET /api-account/models / /{model_path} / /filters — full catalog with pricing and capabilities (public, no auth required)
  • GET /api-account/providers (+ /{id}/stats) — providers, health, throughput (public)
  • GET /api-account/rankings/all — leaderboards, benchmarks, speed rankings (public)
  • GET /api-account/health/{routes,summary} — route health & availability (public)
  • GET /api-account/user/{api-keys,usage,billing,balance} — web-session token only, not callable with your Bearer API key (you'll get 401 auth_error / invalid_token). Manage these in Settings → API Keys / Billing on https://alltoken.ai.

Project Setup

Step 1 — Initialize project

mkdir my-alltoken-agent && cd my-alltoken-agent
npm init -y
npm pkg set type="module"

Step 2 — Install dependencies

npm install openai zod eventemitter3
npm install ink react        # optional: TUI only
npm install -D typescript @types/react tsx

Step 3 — tsconfig.json

{
  "compilerOptions": {
    "target": "ES2022",
    "module": "NodeNext",
    "moduleResolution": "NodeNext",
    "jsx": "react-jsx",
    "strict": true,
    "esModuleInterop": true,
    "skipLibCheck": true,
    "outDir": "dist"
  },
  "include": ["src"]
}

Step 4 — Scripts in package.json

{
  "scripts": {
    "start": "tsx src/cli.tsx",
    "start:headless": "tsx src/headless.ts",
    "dev": "tsx watch src/cli.tsx"
  }
}

Step 5 — File layout

src/
├── client.ts       # AllToken client (OpenAI SDK with overridden baseURL)
├── agent.ts        # Standalone agent core with hooks
├── tools.ts        # Function-calling tool definitions
├── media.ts        # Async image + video helpers (poll loop)
├── cli.tsx         # Optional Ink TUI
└── headless.ts     # Headless / scriptable example

Step 1 — AllToken Client

Create src/client.ts. AllToken is OpenAI-compatible; we just override the base URL.

import OpenAI from 'openai';

export function createAllTokenClient(apiKey = process.env.ALLTOKEN_API_KEY): OpenAI {
  if (!apiKey) throw new Error('ALLTOKEN_API_KEY is not set');
  return new OpenAI({
    apiKey,
    baseURL: 'https://api.alltoken.ai/v1',
  });
}

Step 2 — Agent Core with Hooks

Create src/agent.ts — the standalone agent. It streams via OpenAI's SSE protocol and emits typed events for any UI to consume.

import OpenAI from 'openai';
import type {
  ChatCompletionMessageParam,
  ChatCompletionTool,
  ChatCompletionToolMessageParam,
} from 'openai/resources/chat/completions';
import { EventEmitter } from 'eventemitter3';
import { createAllTokenClient } from './client.js';

export interface Message {
  role: 'user' | 'assistant' | 'system' | 'tool';
  content: string;
  tool_call_id?: string;
  name?: string;
}

export interface AgentEvents {
  'message:user': (message: Message) => void;
  'message:assistant': (message: Message) => void;
  'stream:start': () => void;
  'stream:delta': (delta: string, accumulated: string) => void;
  'stream:end': (fullText: string) => void;
  'tool:call': (name: string, args: unknown, callId: string) => void;
  'tool:result': (name: string, result: unknown, callId: string) => void;
  'thinking:start': () => void;
  'thinking:end': () => void;
  'error': (error: Error) => void;
}

export interface ToolHandler {
  definition: ChatCompletionTool;
  execute: (args: any) => Promise\x3Cunknown> | unknown;
}

export interface AgentConfig {
  apiKey?: string;
  model?: string;                  // e.g. 'minimax-m2.7', 'gpt-5.4'
  instructions?: string;
  tools?: ToolHandler[];
  maxSteps?: number;               // tool-loop step limit
  temperature?: number;
  enableSearch?: boolean;          // AllToken-specific web-search toggle
}

export class Agent extends EventEmitter\x3CAgentEvents> {
  private client: OpenAI;
  private messages: ChatCompletionMessageParam[] = [];
  private cfg: Required\x3COmit\x3CAgentConfig, 'apiKey'>>;
  private toolMap: Map\x3Cstring, ToolHandler>;

  constructor(config: AgentConfig = {}) {
    super();
    this.client = createAllTokenClient(config.apiKey);
    this.cfg = {

      instructions: config.instructions ?? 'You are a helpful assistant.',
      tools: config.tools ?? [],
      maxSteps: config.maxSteps ?? 5,
      temperature: config.temperature ?? 0.7,
      enableSearch: config.enableSearch ?? false,
    };
    this.toolMap = new Map(this.cfg.tools.map((t) => [t.definition.function.name, t]));
    if (this.cfg.instructions) {
      this.messages.push({ role: 'system', content: this.cfg.instructions });
    }
  }

  getMessages(): ChatCompletionMessageParam[] { return [...this.messages]; }
  clearHistory(): void {
    this.messages = this.cfg.instructions
      ? [{ role: 'system', content: this.cfg.instructions }]
      : [];
  }
  setInstructions(text: string): void {
    this.cfg.instructions = text;
    if (this.messages[0]?.role === 'system') this.messages[0] = { role: 'system', content: text };
    else this.messages.unshift({ role: 'system', content: text });
  }
  addTool(t: ToolHandler): void {
    this.cfg.tools.push(t);
    this.toolMap.set(t.definition.function.name, t);
  }

  /** Send a user message, run the tool-loop, stream tokens. Returns the final assistant text. */
  async send(content: string): Promise\x3Cstring> {
    this.messages.push({ role: 'user', content });
    this.emit('message:user', { role: 'user', content });
    this.emit('thinking:start');

    let finalText = '';

    try {

          tools: this.cfg.tools.length ? this.cfg.tools.map((t) => t.definition) : undefined,
          stream: true,
          // AllToken extension: opt-in web search (model-dependent)
          ...(this.cfg.enableSearch ? ({ enable_search: true } as any) : {}),

        this.emit('stream:start');
        let text = '';

            }
          }
          if (choice.finish_reason) finishReason = choice.finish_reason;
        }

        this.emit('stream:end', text);

        // Persist the assistant turn (with tool_calls if any)
        const calls = Object.values(toolCalls).filter((c) => c.id && c.name);
        if (calls.length) {
          this.messages.push({
            role: 'assistant',
            content: text || null,
            tool_calls: calls.map((c) => ({
              id: c.id!,
              type: 'function',
              function: { name: c.name!, arguments: c.args || '{}' },
            })),
          } as any);

          // Execute tools and append results
          for (const c of calls) {

      this.emit('error', error);
      throw error;
    } finally {
      this.emit('thinking:end');
    }
  }

  /** Non-streaming convenience method. */
  async sendSync(content: string): Promise\x3Cstring> {
    this.messages.push({ role: 'user', content });
    this.emit('message:user', { role: 'user', content });
    const res = await this.client.chat.completions.create({
      model: this.cfg.model,
      messages: this.messages,
      temperature: this.cfg.temperature,

function safeJson(s: string): unknown {
  try { return JSON.parse(s || '{}'); } catch { return { _raw: s }; }
}

export function createAgent(config: AgentConfig = {}): Agent {
  return new Agent(config);
}

Step 3 — Define Tools

Create src/tools.ts:

import type { ToolHandler } from './agent.js';

export const timeTool: ToolHandler = {
  definition: {
    type: 'function',
    function: {
      name: 'get_current_time',
      description: 'Get the current date and time',
      parameters: {
        type: 'object',
        properties: {
          timezone: { type: 'string', description: 'IANA timezone, e.g. "UTC", "America/New_York"' },
        },
      },
    },
  },
  execute: ({ timezone }: { timezone?: string }) => ({
    time: new Date().toLocaleString('en-US', { timeZone: timezone || 'UTC' }),
    timezone: timezone || 'UTC',
  }),
};

export const calculatorTool: ToolHandler = {
  definition: {
    type: 'function',
    function: {
      name: 'calculate',
      description: 'Evaluate a basic math expression',
      parameters: {
        type: 'object',
        properties: { expression: { type: 'string' } },
        required: ['expression'],
      },
    },
  },
  execute: ({ expression }: { expression: string }) => {
    // Safe arithmetic evaluator — shunting-yard + RPN, no eval/Function.
    const tokens = expression.match(/\d+(?:\.\d+)?|[+\-*/()]/g) ?? [];
    const prec: Record\x3Cstring, number> = { '+': 1, '-': 1, '*': 2, '/': 2 };
    const out: string[] = [];
    const ops: string[] = [];
    for (const t of tokens) {
      if (/^\d/.test(t)) {
        out.push(t);
      } else if (t === '(') {
        ops.push(t);
      } else if (t === ')') {
        while (ops.length && ops[ops.length - 1] !== '(') out.push(ops.pop()!);
        ops.pop();
      } else {
        while (
          ops.length &&
          ops[ops.length - 1] !== '(' &&
          (prec[ops[ops.length - 1]] ?? 0) >= prec[t]
        ) {
          out.push(ops.pop()!);
        }
        ops.push(t);
      }
    }
    while (ops.length) out.push(ops.pop()!);
    const stack: number[] = [];
    for (const t of out) {
      if (/^\d/.test(t)) {
        stack.push(parseFloat(t));
      } else {
        const b = stack.pop()!;
        const a = stack.pop()!;
        stack.push(t === '+' ? a + b : t === '-' ? a - b : t === '*' ? a * b : a / b);
      }
    }
    return { expression, result: stack[0] };
  },
};

export const defaultTools = [timeTool, calculatorTool];

Step 4 — Image & Video helpers

AllToken's image and video endpoints are asynchronous: create a task, poll until completed, then read the result. Create src/media.ts:

import { createAllTokenClient } from './client.js';

const BASE = 'https://api.alltoken.ai/v1';

async function authedFetch(path: string, init: RequestInit = {}) {
  const apiKey = process.env.ALLTOKEN_API_KEY;
  if (!apiKey) throw new Error('ALLTOKEN_API_KEY is not set');
  const res = await fetch(`${BASE}${path}`, {
    ...init,
    headers: {
      'Authorization': `Bearer ${apiKey}`,
      'Content-Type': 'application/json',
      ...(init.headers ?? {}),
    },
  });
  if (!res.ok) {
    const body = await res.text();
    throw new Error(`AllToken ${res.status}: ${body}`);
  }
  return res.json();
}

// ── Images ────────────────────────────────────────────────────────────────
// Result is delivered ONCE: persist `b64_json` immediately. Tasks expire in 30 min.

export interface ImageRequest {
  model?: 'gpt-image-2' | string;          // discover via GET /images/models
  prompt: string;
  size?: '1024x1024' | '1536x1024' | '1024x1536' | 'auto';
  quality?: 'low' | 'medium' | 'high' | 'auto';
  output_format?: 'png' | 'jpeg' | 'webp';
  background?: 'auto' | 'opaque';
  moderation?: 'auto' | 'low';
}

export interface ImageResult {
  id: string;
  status: 'queued' | 'processing' | 'completed' | 'failed' | 'cancelled';
  data?: Array\x3C{ b64_json: string; revised_prompt?: string }>;
  error?: unknown;
}

export async function generateImage(req: ImageRequest, opts: { pollMs?: number } = {}): Promise\x3CImageResult> {
  const created = await authedFetch('/images/generations/async', {
    method: 'POST',
    body: JSON.stringify({ model: 'gpt-image-2', ...req }),
    // Recommended: deduplicate retries with an Idempotency-Key
    headers: { 'Idempotency-Key': crypto.randomUUID() },
  });

  const id = created.id as string;
  const intervalMs = opts.pollMs ?? 2000;
  while (true) {
    const status = await authedFetch(`/images/generations/${id}`);
    if (status.status === 'completed' || status.status === 'failed' || status.status === 'cancelled') {
      return status;
    }
    await new Promise((r) => setTimeout(r, intervalMs));
  }
}

// ── Videos ────────────────────────────────────────────────────────────────

export interface VideoRequest {
  model: 'seedance-1.5-pro' | 'seedance-2.0' | string;
  prompt: string;
  duration?: number;                       // seconds; -1 = model decides
  ratio?: '16:9' | '9:16' | '4:3' | '3:4' | '21:9' | '1:1' | 'adaptive';
  resolution?: '480p' | '720p' | '1080p';
  generate_audio?: boolean;
  seed?: number;
  watermark?: boolean;
  callback_url?: string;
  // Image-to-video: pass `content` with image_url + role: 'first_frame'
  content?: Array\x3C{
    type: 'image_url' | 'video_url' | 'audio_url' | 'draft_task';
    image_url?: { url: string };
    video_url?: { url: string };
    audio_url?: { url: string };
    role?: 'first_frame' | 'last_frame' | 'reference_image' | 'reference_video' | 'reference_audio';
  }>;
}

export async function generateVideo(req: VideoRequest, opts: { pollMs?: number } = {}) {
  const created = await authedFetch('/videos/generations', {
    method: 'POST',
    body: JSON.stringify(req),
  });
  const id = created.id as string;
  const intervalMs = opts.pollMs ?? 3000;
  while (true) {
    const status = await authedFetch(`/videos/generations/${id}`);
    if (['completed', 'failed', 'cancelled', 'expired'].includes(status.status)) return status;
    await new Promise((r) => setTimeout(r, intervalMs));
  }
}

export async function cancelVideo(id: string) {
  return authedFetch(`/videos/generations/${id}/cancel`, { method: 'POST' });
}

Persist b64_json to disk in one shot — re-polling a delivered image returns 410 image_already_retrieved and the result is gone. The 410 envelope:

{"error":{"code":"image_already_retrieved","message":"Image data was already retrieved; please submit a new generation request","request_id":"...","type":"invalid_request_error"}}

Observed latencies (use these to size your retry budget, not as SLAs):

• Image gpt-image-2 1024×1024 quality=low: ~15–25 s end-to-end (verified 20.6 s on a real submit).
• Image quality=high or 1536×1024: 30–60 s per docs.
• Video seedance-1.5-pro 5 s @ 480 p: 30–120 s typical; 1080 p can take 3–5 min.
• Recommended poll interval: 2 s for images, 3 s for videos.

Submit-response fields (the full shape, not just id):

{"id":"igen_d3b8...","status":"queued","model":"gpt-image-2","created_at":"2026-05-12T13:46:09Z"}

After status==completed, the GET adds: data: [{b64_json}], usage: {input_tokens, output_tokens, total_tokens, input_tokens_details}, size, quality, output_format, completed_at, expires_at. Note: revised_prompt is not present in current responses despite appearing in the docs example — treat it as optional.

Step 5 — Headless usage

Create src/headless.ts:

import { createAgent } from './agent.js';
import { defaultTools } from './tools.js';
import { generateImage } from './media.js';
import { writeFile } from 'node:fs/promises';

async function main() {
  const agent = createAgent({
    model: 'minimax-m2.7',
    instructions: 'You are a helpful assistant with tools.',
    tools: defaultTools,
    enableSearch: false,
  });

  agent.on('thinking:start', () => console.log('\
🤔 Thinking...'));
  agent.on('tool:call', (name, args) => console.log(`🔧 ${name}`, args));
  agent.on('stream:delta', (delta) => process.stdout.write(delta));
  agent.on('stream:end', () => console.log());
  agent.on('error', (e) => console.error('❌', e.message));

  // Chat
  await agent.send('What time is it in Tokyo?');

  // Image (async)
  const img = await generateImage({
    prompt: 'A clean studio product photo of a glass teapot on a walnut table',
    size: '1024x1024',
    quality: 'high',
  });
  if (img.status === 'completed' && img.data?.[0]?.b64_json) {
    await writeFile('teapot.png', Buffer.from(img.data[0].b64_json, 'base64'));
    console.log('\
💾 Saved teapot.png');
  }

Step 6 — Optional Ink TUI

Create src/cli.tsx for a terminal chat UI. Subscribe to stream:delta and tool:call events from the agent and render them. The agent core is UI-agnostic — the same instance can power Hermes, OpenClaw, Discord, or HTTP.

import React, { useState, useEffect, useCallback } from 'react';
import { render, Box, Text, useInput, useApp } from 'ink';
import { createAgent, type Message } from './agent.js';
import { defaultTools } from './tools.js';

const agent = createAgent({
  model: 'minimax-m2.7',
  instructions: 'You are a concise assistant.',
  tools: defaultTools,
});

function App() {
  const { exit } = useApp();
  const [messages, setMessages] = useState\x3CMessage[]>([]);
  const [input, setInput] = useState('');
  const [streaming, setStreaming] = useState('');
  const [loading, setLoading] = useState(false);

  useInput((ch, key) => {
    if (key.escape) exit();
    if (loading) return;
    if (key.return) {
      const text = input.trim();
      if (!text) return;
      setInput('');
      setMessages((m) => [...m, { role: 'user', content: text }]);
      agent.send(text);
    } else if (key.backspace || key.delete) setInput((v) => v.slice(0, -1));
    else if (ch && !key.ctrl && !key.meta) setInput((v) => v + ch);
  });

  useEffect(() => {
    const onStart = () => { setLoading(true); setStreaming(''); };
    const onDelta = (_d: string, acc: string) => setStreaming(acc);
    const onAssistant = (m: Message) => {
      setMessages((prev) => [...prev, m]);
      setStreaming('');
      setLoading(false);
    };
    agent.on('thinking:start', onStart);
    agent.on('stream:delta', onDelta);
    agent.on('message:assistant', onAssistant);
    return () => {
      agent.off('thinking:start', onStart);
      agent.off('stream:delta', onDelta);
      agent.off('message:assistant', onAssistant);
    };
  }, []);

  return (
    \x3CBox flexDirection="column" padding={1}>
      \x3CText bold color="magenta">🤖 AllToken Agent\x3C/Text>
      {messages.map((m, i) => (
        \x3CBox key={i} flexDirection="column" marginTop={1}>
          \x3CText bold color={m.role === 'user' ? 'cyan' : 'green'}>
            {m.role === 'user' ? '▶ You' : '◀ Assistant'}
          \x3C/Text>
          \x3CText wrap="wrap">{m.content}\x3C/Text>
        \x3C/Box>
      ))}
      {streaming && (
        \x3CBox flexDirection="column" marginTop={1}>
          \x3CText bold color="green">◀ Assistant\x3C/Text>
          \x3CText wrap="wrap">{streaming}\x3CText color="gray">▌\x3C/Text>\x3C/Text>
        \x3C/Box>
      )}
      \x3CBox borderStyle="single" borderColor="gray" marginTop={1} paddingX={1}>
        \x3CText color="yellow">{'> '}\x3C/Text>
        \x3CText>{input}\x3C/Text>
        \x3CText color="gray">{loading ? ' ···' : '█'}\x3C/Text>
      \x3C/Box>
    \x3C/Box>
  );
}

render(\x3CApp />);

Python equivalent (one-file)

For Python users — including those embedding the agent inside Hermes or OpenClaw Python tools:

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["ALLTOKEN_API_KEY"],
    base_url="https://api.alltoken.ai/v1",
)

# Streaming chat
stream = client.chat.completions.create(
    model="minimax-m2.7",
    messages=[{"role": "user", "content": "Explain SSE in one sentence."}],
    stream=True,
)
for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
print()

Async image (poll loop):

import os, time, base64, uuid, requests

BASE = "https://api.alltoken.ai/v1"
H = {"Authorization": f"Bearer {os.environ['ALLTOKEN_API_KEY']}", "Content-Type": "application/json"}

task = requests.post(
    f"{BASE}/images/generations/async",
    headers={**H, "Idempotency-Key": str(uuid.uuid4())},
    json={"model": "gpt-image-2", "prompt": "A cat astronaut, studio light", "size": "1024x1024", "quality": "high"},
).json()

while True:
    res = requests.get(f"{BASE}/images/generations/{task['id']}", headers=H).json()
    if res["status"] in ("completed", "failed", "cancelled"):
        break
    time.sleep(2)

if res["status"] == "completed":
    with open("cat.png", "wb") as f:
        f.write(base64.b64decode(res["data"][0]["b64_json"]))

Using AllToken from inside Hermes / OpenClaw

Both Hermes and OpenClaw load skills from SKILL.md files and can run TypeScript or Python tools at the agent boundary. There are two integration patterns:

Pattern A — AllToken as your agent's model provider

Point your host agent's HTTP client at AllToken. In OpenClaw / Hermes config, set:

provider:
  base_url: https://api.alltoken.ai/v1
  api_key: ${ALLTOKEN_API_KEY}
model: minimax-m2.7

No code changes needed — the OpenAI-compatible endpoint accepts the same requests.

Pattern B — AllToken as a tool inside another agent

Drop the agent.ts / media.ts modules into the host agent's tools directory and expose them as callable tools (chat, generate_image, generate_video). The host agent (running on any model) then delegates multimodal work to AllToken on demand.

// host-agent-tool.ts
import { createAgent } from './agent.js';
import { generateImage, generateVideo } from './media.js';

const alltoken = createAgent({ model: 'minimax-m2.7' });

export const tools = {
  alltoken_chat: (input: { prompt: string }) => alltoken.sendSync(input.prompt),
  alltoken_image: (input: { prompt: string; size?: string }) => generateImage(input as any),
  alltoken_video: (input: { prompt: string; duration?: number }) =>
    generateVideo({ model: 'seedance-1.5-pro', ...input }),
};

Discovering models

Verified-working model IDs as of 2026-05-12 (use these for quick starts; re-confirm via GET /v1/models before production):

Available chat models on a fresh key: 38 as of this writing. Image: 1. Video: 7.

Do not hardcode model IDs in production — the catalog evolves. Use the live endpoints:

// OpenAI-compatible list (good for SDK clients)
const list = await fetch('https://api.alltoken.ai/v1/models', {
  headers: { Authorization: `Bearer ${process.env.ALLTOKEN_API_KEY}` },
}).then((r) => r.json());

// Rich catalog with pricing, capabilities, tags (used by the website)
const catalog = await fetch('https://api.alltoken.ai/api-account/models').then((r) => r.json());

// Single model detail page
const detail = await fetch('https://api.alltoken.ai/api-account/models/gpt-5.4').then((r) => r.json());

Pair with the Rankings API (GET /api-account/rankings/all) for live leaderboards by usage, benchmarks, throughput, and category leaders — useful for --auto model selection.

Routing & fallbacks

AllToken handles provider routing internally. Two knobs:

• Account-level default routing — set routing_mode (code or manual), allowed_models, and a default_models priority list on each API key:

  POST   /api-account/user/api-keys
  PUT    /api-account/user/api-keys/{key_id}/default-models
  

• Per-request override — pass the exact model ID in the request body to bypass routing for that call.

When a provider returns 502/503, AllToken may automatically fall back to the next provider for the model.

Web search (enable_search)

Pass enable_search: true on a chat completion to opt into AllToken's unified web-search backend. Support is per-provider, not per-request shape — same flag, different effective behavior across model families. Live probe on 2026-05-12 (asking "current Bitcoin price"):

Recommendation: when you need search, default to a DeepSeek or Qwen model. If you're on a different family, fall back to a function-calling pattern (model emits a tool call → your tool hits a search API → you re-invoke). The enable_search matrix above is empirical and provider-side support may change — re-test for critical paths.

Note: AllToken does not include search-result citations in the response annotations[] field today, so detecting "did search fire" requires latency heuristics (typically +6 – 15 s vs no-search baseline) or content sniffing for fresh facts.

Health, rate limits, errors

• Per-key rate limits: set rpm_limit, tpm_limit, monthly_quota, credit_limit when creating the key.
• Status codes you should handle: 400 invalid params · 401 bad key · 402 insufficient balance · 403 forbidden · 404 not found · 429 rate limited (respect Retry-After) · 5xx upstream — already retried server-side when safe.
• Error envelope (real wire format):

  {
    "error": {
      "code": "invalid_api_key",
      "message": "Invalid or revoked API key",
      "param": null,
      "type": "auth_error",
      "request_id": "d81itf8gdg1fp5ko4bjg"
    }
  }
  

  Note: code is a string slug (e.g. "invalid_api_key", "image_already_retrieved", "all_providers_failed"), not the numeric HTTP status. type groups errors (auth_error, invalid_request_error, api_error, …). Include request_id when filing support tickets.

Python error-dispatch helper:

import json, time, urllib.request, urllib.error

def call(req):
    try:
        return urllib.request.urlopen(req, timeout=60)
    except urllib.error.HTTPError as e:
        body = e.read()
        try:
            err = json.loads(body).get("error", {})
        except Exception:
            err = {}
        retry_after = e.headers.get("Retry-After")     # integer seconds (AllToken format)
        if e.code == 429 and retry_after:
            time.sleep(int(retry_after))
            return call(req)                            # one retry
        if e.code == 401:    raise RuntimeError(f"auth: {err.get('code')} — rotate API key")
        if e.code == 402:    raise RuntimeError(f"top up credits: {err.get('message')}")
        if e.code == 410 and err.get("code") == "image_already_retrieved":
            raise RuntimeError("re-submit; image was already delivered")
        if 500 \x3C= e.code \x3C 600 and err.get("code") == "all_providers_failed":
            raise RuntimeError("upstream — try fallback model or retry with jitter")
        raise RuntimeError(f"{e.code} {err.get('type')}/{err.get('code')}: {err.get('message')} [req={err.get('request_id')}]")

Retry-After is sent as integer seconds. Always combine an explicit retry-after read with exponential backoff (+ jitter) as the fallback when the header is missing.

• Health dashboard: GET /api-account/health/summary (returns {"data": {...}} envelope) and /health/routes show live availability, p50/p95 latency, and incident routes — wire this into your runbook.

Cost tracking & budgets

Per-request cost: every chat response includes a usage block:

"usage": {
  "prompt_tokens": 13,
  "completion_tokens": 4,
  "total_tokens": 17,
  "prompt_tokens_details": { "cached_tokens": 0, "cache_creation_input_tokens": 0, "audio_tokens": 0 },
  "completion_tokens_details": { "reasoning_tokens": 0, "audio_tokens": 0, "accepted_prediction_tokens": 0, "rejected_prediction_tokens": 0 }
}

Capture usage from a streaming response: pass stream_options: {"include_usage": true}. The final data: chunk before data: [DONE] will have choices: [] and the populated usage. Without this option, usage is null on every streamed chunk.

stream = client.chat.completions.create(
    model="gpt-5.4-nano", messages=[...], stream=True,
    stream_options={"include_usage": True},
)
usage = None
for chunk in stream:
    if chunk.choices and chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="", flush=True)
    if chunk.usage is not None:
        usage = chunk.usage   # only present on the terminal chunk

Per-request cost telemetry (vendor extension): AllToken also emits one extra SSE comment line after data: [DONE] with a fiat-priced breakdown:

: {"cost":"0.0000188000","input_price":"0.0002000000","output_price":"0.0012500000","prompt_tokens":19,"completion_tokens":12}

Standard OpenAI SDKs drop comment lines (lines beginning with :), so this is invisible when using openai. To capture it, parse the raw SSE stream yourself and do not stop on [DONE]:

# stdlib-only — captures both usage (from data: chunks) AND cost comment (post-DONE)
import urllib.request, json
req = urllib.request.Request(URL, data=BODY, method="POST", headers=H)
r = urllib.request.urlopen(req)
saw_done = False
for raw in iter(r.readline, b""):
    line = raw.decode().rstrip("\
")
    if line.startswith(":"):
        cost = json.loads(line[1:])      # {"cost": "...", ...}
    elif line.startswith("data: "):
        data = line[6:]
        if data == "[DONE]": saw_done = True; continue
        # ... parse chunk

Other useful response metadata: chat responses also carry top-level service_tier (e.g. "default") and x-gateway-request-id (use this when filing support tickets).

Account-wide totals: /api-account/user/{balance,billing,usage,billing/orders,...} exist but are not callable with the API key — they need the web-session token. Check balance and history in Settings → Billing on https://alltoken.ai, or top up via the same dashboard.

Extending the Agent

Custom hooks

const agent = createAgent({ model: 'minimax-m2.7' });

agent.on('message:user',      (m) => db.insert('user', m.content));
agent.on('message:assistant', (m) => db.insert('assistant', m.content));
agent.on('tool:call',         (name, args) => analytics.track('tool', { name, args }));
agent.on('error',             (err) => sentry.capture(err));

HTTP server (one agent per session)

import express from 'express';
import { createAgent, type Agent } from './agent.js';

const app = express(); app.use(express.json());
const sessions = new Map\x3Cstring, Agent>();

app.post('/chat', async (req, res) => {
  const { sessionId, message } = req.body;
  let agent = sessions.get(sessionId);
  if (!agent) { agent = createAgent(); sessions.set(sessionId, agent); }
  res.json({ response: await agent.sendSync(message), history: agent.getMessages() });
});

app.listen(3000);
