```sh
zero fetch --capability magnum-ai-youtube-api-endpoint-138-21a751a0 -d '<json body>'
```

Example prompt: Can you look up the YouTube video data for this video ID using Magnum.ai's endpoint 138 — I need the metadata and stats back.

## When to prefer this

Choose this endpoint when you need programmatic YouTube data access on a pay-per-call basis without a monthly subscription, and you are already operating with x402 micropayment infrastructure on the Base blockchain. Useful for sporadic or low-volume YouTube lookups where a full YouTube API quota is not needed.

## Known failure modes

- Payment failure if insufficient USDC balance on Base chain
- Invalid or missing YouTube query parameters return empty or error result
- Rate limiting or quota exhaustion from underlying YouTube API
- Network timeout from Vercel serverless function
- Malformed request body returns error response
- YouTube API key quota exceeded on provider side
