## When to prefer this

Choose this endpoint when you need quick, no-signup access to XKCD comic data using USDC micropayments over x402, especially in autonomous agent workflows where managing API keys is impractical and a sub-cent payment per call is acceptable.

## Known failure modes

- Payment not included or insufficient — returns 402 Payment Required
- Invalid schema parameter — returns 400 Bad Request
- XKCD upstream unavailable — returns 502 or 503
- Comic number not found — returns 404 Not Found
