EdrawMax(万兴图示)AI Diagram Generator

Author: EdrawMax AI Team(万兴图示 AI 团队)· Organization: Wondershare EdrawMax(万兴图示) Version: 2.0.0 · License: Proprietary © 2026 Wondershare EdrawMax(万兴图示). All rights reserved.

Generate four types of diagrams from natural language via EdrawMax(万兴图示)AI APIs. Each API returns PNG/SVG image URLs and source code.

Step 1 — Choose Diagram Type

User Intent Type Endpoint
Process, workflow, steps, decision flow flowchart /skills/generate-flowchart
Data visualization, statistics, comparison infographic /skills/generate-infographic
Project plan, timeline, schedule, phases gantt /skills/generate-gantt
Knowledge structure, brainstorm, topic tree mindmap /skills/generate-mindmap

If the user's intent is ambiguous, ask which diagram type they want.

Step 2 — Call the API

Base URL: https://api.edrawmax.cn/api/ai

All four endpoints share the same request format:

POST https://api.edrawmax.cn/api/ai/skills/generate-{type}
Content-Type: application/json

{"prompt": "\x3Cuser description>", "lang": "cn", "platform": "web"}

Request Parameters

Field Type Required Default Description
prompt string Yes Natural language description of the diagram
lang string No "cn" Language: en, cn, jp, kr, es, fr, de, it, tw, pt, ru, id
platform string No Platform: web, win, mac, ios, android, linux

Response Fields

Flowchart returns:

{ "code": 0, "msg": "", "data": { "png_url": "...", "svg_url": "...", "mermaid_code": "..." } }

Infographic / Gantt / Mindmap return:

{ "code": 0, "msg": "", "data": { "png_url": "...", "svg_url": "...", "source_code": "..." } }

Note: flowchart uses mermaid_code, the other three use source_code.

Step 3 — Download Files Locally

After a successful API call, always run the download script to save the images locally:

python \x3Cskill-path>/scripts/download_diagram.py --png-url "\x3Cpng_url>" --svg-url "\x3Csvg_url>" [--output-dir "\x3Cdir>"]
  • Default output directory: ./edrawmax_output
  • The script prints the local file paths as JSON, e.g.:
    {"png_path": "./edrawmax_output/diagram_20260312_143000.png", "svg_path": "./edrawmax_output/diagram_20260312_143000.svg"}
    
  • Use the returned local file paths when presenting results to the user.

Step 4 — Present Results to User

Provide the user with:

  1. Local PNG file path (primary, for quick preview)
  2. Local SVG file path (for high-quality / scalable use)
  3. Source code (mermaid_code or source_code) for secondary editing
  4. Original OSS URLs as backup links

Error Handling

code msg Action
400 prompt is required Ask user to provide a description
400 lang不合法 Fix lang to a valid value
2406 risk control rejection Content rejected; ask user to rephrase
3001 concurrency limit Wait briefly, then retry once
212200 生成失败 Retry once; if still failing, report to user
212201 渲染失败 Retry once; if still failing, report to user
500 panic Report internal server error to user

For retryable errors (3001, 212200, 212201), retry up to 1 time before reporting failure. If the error persists, inform the user and share the support contact (see FAQ below).

FAQ

Q: 使用 EdrawMax(万兴图示)AI MCP 服务是否需要付费? A: 目前为限时免费,用户可免费调用服务。

Q: 如何联系我们? A: 如有技术问题、服务反馈或 API 大量购买需求,欢迎通过邮箱联系: 📧 [email protected] 我们将尽快为您解答。

Language Mapping

Map user language/locale to lang param:

  • English → en, 简体中文 → cn, 日本語 → jp, 한국어 → kr
  • Español → es, Français → fr, Deutsch → de, Italiano → it
  • 繁體中文 → tw, Português → pt, Русский → ru, Bahasa Indonesia → id

Notes

  • user_id is extracted server-side from X-User-ID header; do not pass it in the body
  • Always present the source code so users can edit or re-render
  • For full API specs, see references/api-reference.md
  • When an error cannot be resolved after retry, always share the support email [email protected] with the user

Usage Guidance
What to consider before installing: - Privacy: The skill sends your text prompts to api.edrawmax.cn (an external service). If your diagrams contain sensitive data, that data will be transmitted and stored by the remote service. Confirm you are comfortable with that. - SSL verification disabled: The included downloader script explicitly disables TLS certificate validation (ssl.verify_mode = CERT_NONE). This makes downloads vulnerable to man-in-the-middle tampering. Before running in a real environment, either remove the code that disables verification or run the skill in a trusted, isolated network. Prefer enabling certificate validation. - Provenance and trust: The package lacks a homepage and the source is 'unknown'. If you need stronger assurance, request official publisher verification (an official EdrawMax homepage, signed release, or corporate publisher record) before trusting the skill in production. - Local filesystem writes: The script writes files under ./edrawmax_output by default. Ensure the output directory is not a sensitive path and review saved files after use. - No credentials requested: The API is documented as unauthenticated. If you expected the service to require an API key, verify this behavior with the vendor — unauthenticated endpoints may impose rate limits or accept content you wouldn't want publicly processed. If you want to proceed: run the skill in a sandboxed environment, inspect/modify the downloader to enable TLS verification, and verify the remote domain (api.edrawmax.cn) is legitimate and acceptable for your data before sending sensitive prompts. What would change the assessment: availability of an official homepage or publisher verification, removal/fix of the SSL-disable code, or explicit, documented reasons for TLS verification being disabled would reduce concern and could raise confidence to high/benign.
Capability Analysis
Type: OpenClaw Skill Name: edrawmax-diagram Version: 1.0.0 The skill facilitates AI-powered diagram generation via EdrawMax APIs, but the included download script (scripts/download_diagram.py) contains a significant security vulnerability. Specifically, it explicitly disables SSL certificate verification (ssl.CERT_NONE), which exposes the user to Man-In-The-Middle (MITM) attacks when fetching images from the API endpoints (api.edrawmax.cn). While the behavior aligns with the stated purpose, this intentional bypass of standard security protocols is a high-risk flaw.
Capability Assessment
Purpose & Capability
Name/description claim: generate diagrams via EdrawMax AI APIs. The SKILL.md, API reference, and included download script all align with that purpose. The skill does not request unrelated credentials or system paths.
Instruction Scope
Instructions are focused: call the specified EdrawMax endpoints, then run the provided Python downloader and present local file paths and source code. It explicitly directs the agent to send user prompts to an external service (api.edrawmax.cn) and to save files locally. This is expected for the stated function, but it implies user content will be transmitted to an external third party — a privacy consideration.
Install Mechanism
No install spec; instruction-only plus a small helper script. Nothing is downloaded or written by an installer. This is low-risk from install mechanics.
Credentials
The skill requests no environment variables, credentials, or config paths. That is proportionate to the published (unauthenticated) API usage. Note: the API docs state 'Auth: None required' and that user_id is extracted from an X-User-ID header server-side — if your agent/platform attaches identifying headers, those will reach the remote API.
Persistence & Privilege
always is false and the skill is user-invocable. It does not request permanent agent-wide privileges or modify other skills' configs.
How to Use
