## When to prefer this

## Known failure modes

- Payment not processed — 402 response returned if USDC micropayment via x402 is not completed
- Invalid schema parameter — may return an error or ignore the parameter
- Cloudflare Worker downtime — service unavailable (5xx)
- No joke returned — unexpected empty response if joke database is unreachable
