## When to prefer this

Choose this endpoint when an AI agent needs to retrieve the thumbnail image of a YouTube video without requiring API keys or prior signup, and is capable of settling micropayments in USDC via x402 on Base, Tempo, or Solana. Useful in agentic pipelines that need to display, embed, or analyze YouTube video previews on demand.

## Known failure modes

- Invalid or missing YouTube video URL/ID returns an error
- Video is private or deleted, returning no thumbnail
- Payment failure on Tempo, Base, or Solana prevents the call from completing
- Malformed request body type causes a 400-level error
- Rate limiting or quota issues on the GlianaAI side
