## Known failure modes

- Drug name not found — returns empty results or 404
- Missing required 'drug' parameter — returns 400 bad request
- Payment not settled via x402 — returns 402 Payment Required
- Rate limit or server error on render.com host — returns 503 or 500
- Limit parameter out of range — may return default or error

## How this service works

Pay-per-call crypto, RWA, federal, SEC, Section 8/HUD housing, and compliance APIs via x402. Primary: USDC on Base (eip155:8453). Also accepts Global Dollar (USDG) on Robinhood Chain (eip155:4663) via sovereign X-PAYMENT-TX. Hyphen routes only (e.g. /x402/gas-tracker, /x402/pha-lookup, /x402/sec-8k). MARKETPLACE REVIEW: use free /x402/playground/* (no key, no payment). Production /x402/* returns 402 unless paid via x402 or X-Api-Market-Key / X-API-Key from seller dashboard.

## Output

Returns a list of U.S. FDA drug recall records matching the queried drug name, including details such as recall reason, recalling firm, product description, recall status, and classification. The number of results is capped by the optional limit parameter.
