README (SKILL.md)

Getting Started

Send me your text or prompts and I'll handle the AI video generation. Or just describe what you're after.

Try saying:

  • "generate a short text description of a product demo scene into a 1080p MP4"
  • "generate a 30-second explainer video from this JSON script data"
  • "generating videos from JSON scripts or text prompts for free for developers and content creators"

First-Time Connection

When a user first opens this skill, connect to the processing backend automatically. Briefly let them know (e.g. "Setting up...").

Authentication: Check if NEMO_TOKEN is set in the environment. If it is, skip to step 2.

  1. Obtain a free token: Generate a random UUID as client identifier. POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id set to that UUID. The response data.token is your NEMO_TOKEN — 100 free credits, valid 7 days.
  2. Create a session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Authorization: Bearer \x3Ctoken>, Content-Type: application/json, and body {"task_name":"project","language":"\x3Cdetected>"}. Store the returned session_id for all subsequent requests.

Keep setup communication brief. Don't display raw API responses or token values to the user.

JSON AI Video Generator Free — Generate Videos from JSON Data

Drop your text or prompts in the chat and tell me what you need. I'll handle the AI video generation on cloud GPUs — you don't need anything installed locally.

Here's a typical use: you send a a short text description of a product demo scene, ask for generate a 30-second explainer video from this JSON script data, and about 1-2 minutes later you've got a MP4 file ready to download. The whole thing runs at 1080p by default.

One thing worth knowing — shorter JSON scripts with clear scene descriptions produce the most accurate video output.

Matching Input to Actions

User prompts referencing json ai 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.

All calls go to https://mega-api-prod.nemovideo.ai. The main endpoints:

  1. SessionPOST /api/tasks/me/with-session/nemo_agent with {"task_name":"project","language":"\x3Clang>"}. Gives you a session_id.
  2. Chat (SSE)POST /run_sse with session_id and your message in new_message.parts[0].text. Set Accept: text/event-stream. Up to 15 min.
  3. UploadPOST /api/upload-video/nemo_agent/me/\x3Csid> — multipart file or JSON with URLs.
  4. CreditsGET /api/credits/balance/simple — returns available, frozen, total.
  5. StateGET /api/state/nemo_agent/me/\x3Csid>/latest — current draft and media info.
  6. ExportPOST /api/render/proxy/lambda with render ID and draft JSON. Poll GET /api/render/proxy/lambda/\x3Cid> every 30s for completed status and download URL.

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

Three attribution headers are required on every request and must match this file's frontmatter:

Header Value
X-Skill-Source json-ai-video-generator-free
X-Skill-Version frontmatter version
X-Skill-Platform auto-detect: clawhub / cursor / unknown from install path

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.

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)

Translating GUI Instructions

The backend responds as if there's a visual interface. Map its instructions to API calls:

  • "click" or "点击" → execute the action via the relevant endpoint
  • "open" or "打开" → query session state to get the data
  • "drag/drop" or "拖拽" → send the edit command through SSE
  • "preview in timeline" → show a text summary of current tracks
  • "Export" or "导出" → run the export workflow

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.

Error Handling

Code Meaning Action
0 Success Continue
1001 Bad/expired token Re-auth via anonymous-token (tokens expire after 7 days)
1002 Session not found New session §3.0
2001 No credits Anonymous: show registration URL with ?bind=\x3Cid> (get \x3Cid> from create-session or state response when needed). Registered: "Top up credits in your account"
4001 Unsupported file Show supported formats
4002 File too large Suggest compress/trim
400 Missing X-Client-Id Generate Client-Id and retry (see §1)
402 Free plan export blocked Subscription tier issue, NOT credits. "Register or upgrade your plan to unlock export."
429 Rate limit (1 token/client/7 days) Retry in 30s once

Common Workflows

Quick edit: Upload → "generate a 30-second explainer video from this JSON script data" → 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.

Tips and Tricks

The backend processes faster when you're specific. Instead of "make it look better", try "generate a 30-second explainer video from this JSON script data" — concrete instructions get better results.

Max file size is 200MB. Stick to JSON, TXT, MP4, MOV for the smoothest experience.

Export as MP4 for widest compatibility across platforms and devices.

Usage Guidance
This skill appears to be a thin client for a remote video-rendering service and mostly does what it says, but ask the publisher to clarify two things before installing: (1) exactly where the NEMO_TOKEN and session_id will be stored (the SKILL.md frontmatter mentions ~/.config/nemovideo/ but registry metadata omitted it); (2) why responses and token values are explicitly hidden from the user (this prevents you from seeing the token or raw API replies). If you proceed, consider creating a dedicated/limited token account for this service (or use ephemeral environment variables), monitor network activity, and avoid giving any unrelated credentials. If you need high assurance, request the skill to be updated to explicitly state persistence behavior and to show the user the created anonymous account ID or provide an opt-in for automatic token creation.
Capability Analysis
Type: OpenClaw Skill Name: json-ai-video-generator-free Version: 1.0.0 The skill bundle is a legitimate integration for the 'nemovideo.ai' video generation service. It provides detailed instructions for the AI agent to handle authentication via anonymous tokens, manage user sessions, and interact with specific API endpoints for video processing and export. While it requests network access and local configuration storage (~/.config/nemovideo/), these actions are directly aligned with its stated purpose of generating and downloading AI videos, and no evidence of data exfiltration or malicious execution was found.
Capability Assessment
Purpose & Capability
The declared purpose (generate videos from JSON/prompts) lines up with the API endpoints and flows described (session, SSE, upload, export). Requesting a single service token (NEMO_TOKEN) is expected. However, the SKILL.md frontmatter lists a config path (~/.config/nemovideo/) that the registry metadata did not declare, which is an inconsistency to clarify.
Instruction Scope
Instructions tell the agent to auto-request an anonymous token from the remote service if NEMO_TOKEN is not present, create and store a session_id, and explicitly instruct the agent to not display raw API responses or token values to the user. The file maps UI actions to API calls and instructs polling and uploads — expected for this purpose — but the hidden token handling and vague guidance about where/how to persist the token/session (frontmatter config path vs registry metadata mismatch) reduce transparency and warrant caution.
Install Mechanism
This is an instruction-only skill with no install spec or code to download or execute. That minimizes on-disk risk.
Credentials
Only one credential (NEMO_TOKEN) is required, which is appropriate for a hosted video API. The skill's runtime also references a config directory in the frontmatter, which the registry didn't list — possible mismatch about where tokens/session state will be stored. The fact the skill can generate a new anonymous token on your behalf means it will create credentials tied to your agent; users should be aware of that external account creation.
Persistence & Privilege
The skill is not always-enabled and does not request elevated platform privileges. It does instruct storing a session token and (implicitly) writing state under a service-specific config path; that is normal for a service client but confirm where data is persisted.
