README (SKILL.md)

Getting Started

Share your text JSON prompts and I'll get started on AI video generation. Or just tell me what you're thinking.

Try saying:

  • "generate my text JSON prompts"
  • "export 1080p MP4"
  • "generate a 30-second product video from"

Getting Connected

Before handling any user request, establish a connection to the backend API. Show a brief status like "Connecting...".

If NEMO_TOKEN is in the environment, use it directly and create a session. Otherwise, acquire a free starter token:

  • Generate a UUID as client identifier
  • POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with the X-Client-Id header
  • The response includes a token with 100 free credits valid for 7 days — use it as NEMO_TOKEN

Then create a session by POSTing to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer authorization and body {"task_name":"project","language":"en"}. The session_id in the response is needed for all following requests.

Tell the user you're ready. Keep the technical details out of the chat.

JSON Prompt Video Generator Free — Generate Videos from JSON Prompts

Send me your text JSON prompts and describe the result you want. The AI video generation runs on remote GPU nodes — nothing to install on your machine.

A quick example: upload a JSON object with scene descriptions, duration, and style parameters, type "generate a 30-second product video from this JSON prompt with voiceover and transitions", and you'll get a 1080p MP4 back in roughly 1-2 minutes. All rendering happens server-side.

Worth noting: keep your JSON prompt concise — shorter scene descriptions render faster and more accurately.

Matching Input to Actions

User prompts referencing json prompt video generator free, aspect ratio, text overlays, or audio tracks get routed to the corresponding action via keyword and intent classification.

User says... Action Skip SSE?
"export" / "导出" / "download" / "send me the video" → §3.5 Export
"credits" / "积分" / "balance" / "余额" → §3.3 Credits
"status" / "状态" / "show tracks" → §3.4 State
"upload" / "上传" / user sends file → §3.2 Upload
Everything else (generate, edit, add BGM…) → §3.1 SSE

Cloud Render Pipeline Details

Each export job queues on a cloud GPU node that composites video layers, applies platform-spec compression (H.264, up to 1080x1920), and returns a download URL within 30-90 seconds. The session token carries render job IDs, so closing the tab before completion orphans the job.

Skill attribution — read from this file's YAML frontmatter at runtime:

  • X-Skill-Source: json-prompt-video-generator-free
  • X-Skill-Version: from frontmatter version
  • X-Skill-Platform: detect from install path (~/.clawhub/clawhub, ~/.cursor/skills/cursor, else unknown)

All requests must include: Authorization: Bearer \x3CNEMO_TOKEN>, X-Skill-Source, X-Skill-Version, X-Skill-Platform. Missing attribution headers will cause export to fail with 402.

API base: https://mega-api-prod.nemovideo.ai

Create session: POST /api/tasks/me/with-session/nemo_agent — body {"task_name":"project","language":"\x3Clang>"} — returns task_id, session_id.

Send message (SSE): POST /run_sse — body {"app_name":"nemo_agent","user_id":"me","session_id":"\x3Csid>","new_message":{"parts":[{"text":"\x3Cmsg>"}]}} with Accept: text/event-stream. Max timeout: 15 minutes.

Upload: POST /api/upload-video/nemo_agent/me/\x3Csid> — file: multipart -F "files=@/path", or URL: {"urls":["\x3Curl>"],"source_type":"url"}

Credits: GET /api/credits/balance/simple — returns available, frozen, total

Session state: GET /api/state/nemo_agent/me/\x3Csid>/latest — key fields: data.state.draft, data.state.video_infos, data.state.generated_media

Export (free, no credits): POST /api/render/proxy/lambda — body {"id":"render_\x3Cts>","sessionId":"\x3Csid>","draft":\x3Cjson>,"output":{"format":"mp4","quality":"high"}}. Poll GET /api/render/proxy/lambda/\x3Cid> every 30s until status = completed. Download URL at output.url.

Supported formats: mp4, mov, avi, webm, mkv, jpg, png, gif, webp, mp3, wav, m4a, aac.

Reading the SSE Stream

Text events go straight to the user (after GUI translation). Tool calls stay internal. Heartbeats and empty data: lines mean the backend is still working — show "⏳ Still working..." every 2 minutes.

About 30% of edit operations close the stream without any text. When that happens, poll /api/state to confirm the timeline changed, then tell the user what was updated.

Backend Response Translation

The backend assumes a GUI exists. Translate these into API actions:

Backend says You do
"click [button]" / "点击" Execute via API
"open [panel]" / "打开" Query session state
"drag/drop" / "拖拽" Send edit via SSE
"preview in timeline" Show track summary
"Export button" / "导出" Execute export workflow

Draft JSON uses short keys: t for tracks, tt for track type (0=video, 1=audio, 7=text), sg for segments, d for duration in ms, m for metadata.

Example timeline summary:

Timeline (3 tracks): 1. Video: city timelapse (0-10s) 2. BGM: Lo-fi (0-10s, 35%) 3. Title: "Urban Dreams" (0-3s)

Error Codes

  • 0 — success, continue normally
  • 1001 — token expired or invalid; re-acquire via /api/auth/anonymous-token
  • 1002 — session not found; create a new one
  • 2001 — out of credits; anonymous users get a registration link with ?bind=\x3Cid>, registered users top up
  • 4001 — unsupported file type; show accepted formats
  • 4002 — file too large; suggest compressing or trimming
  • 400 — missing X-Client-Id; generate one and retry
  • 402 — free plan export blocked; not a credit issue, subscription tier
  • 429 — rate limited; wait 30s and retry once

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "generate a 30-second product video from this JSON prompt with voiceover and transitions" — concrete instructions get better results.

Max file size is 200MB. Stick to JSON, TXT, CSV, YAML for the smoothest experience.

Export as MP4 for widest compatibility.

Common Workflows

Quick edit: Upload → "generate a 30-second product video from this JSON prompt with voiceover and transitions" → Download MP4. Takes 1-2 minutes for a 30-second clip.

Batch style: Upload multiple files in one session. Process them one by one with different instructions. Each gets its own render.

Iterative: Start with a rough cut, preview the result, then refine. The session keeps your timeline state so you can keep tweaking.

Usage Guidance
This skill appears to be a straightforward API client for a third-party video service, but check a few things before installing: 1) Understand that calls (including token exchange) go to https://mega-api-prod.nemovideo.ai — your uploads and any provided NEMO_TOKEN will be sent there. 2) The SKILL.md references a local config path (~/.config/nemovideo/) and asks the agent to detect install paths; confirm whether the skill will read those directories and whether any sensitive tokens live there. 3) If you supply your own NEMO_TOKEN, ensure it is scoped and revocable; otherwise the skill will create an anonymous token automatically. 4) Ask the publisher to resolve the metadata mismatch (registry says no required config paths but SKILL.md lists one) and to document exactly what local files (if any) the agent will access. If you cannot confirm those points, treat this skill as risky for use with sensitive data.
Capability Analysis
Type: OpenClaw Skill Name: json-prompt-video-generator-free Version: 1.0.0 The skill bundle is a functional API wrapper for a video generation service hosted at mega-api-prod.nemovideo.ai. The SKILL.md file provides detailed instructions for the AI agent to manage authentication (including an anonymous token fallback), session state, and file uploads to the remote backend. While it requests access to the NEMO_TOKEN environment variable and performs basic platform detection via installation paths, these actions are transparently documented and aligned with the stated purpose of providing a cloud-based video rendering service. No evidence of data exfiltration, unauthorized execution, or malicious prompt injection was found.
Capability Assessment
Purpose & Capability
The name/description (generate videos from JSON prompts) align with the skill's API calls (session creation, upload, render/export). Requiring a NEMO_TOKEN is expected. However, the SKILL.md frontmatter declares a config path (~/.config/nemovideo/) while the registry metadata listed no required config paths — this mismatch is unexplained and needs clarification.
Instruction Scope
The runtime instructions are focused on the video-generation API (auth, session, SSE, upload, export). They do instruct the agent to read the skill's YAML frontmatter and to detect the install path (e.g., ~/.clawhub, ~/.cursor/skills/) to set X-Skill-Platform; that requires filesystem access. This is plausible for attribution but is scope-expanding compared with a pure API client and could cause accidental exposure if code also attempted to read other local config files.
Install Mechanism
This is an instruction-only skill with no install spec and no code files — nothing is written to disk by the skill itself. That minimizes install-time risk.
Credentials
Only NEMO_TOKEN is declared as required which is proportionate to calling the remote API. But the SKILL.md frontmatter mentions a config path (~/.config/nemovideo/) that could contain additional credentials; the registry metadata did not list this. The skill also implements an anonymous-token flow (POST to the vendor endpoint) when NEMO_TOKEN is absent — expected but means the agent will reach out to the vendor automatically.
Persistence & Privilege
always:false and default autonomous invocation are used. The skill does not request persistent 'always' presence or claim to modify other skills or global agent config.
How to Use
