FDA drug recalls (enforcement reports) API

FDA drug recall enforcement reports from openFDA, newest report first, filtered by optional drug, brand or firm text (every word must match; brand names also match their RxNorm ingredients), look-back months and FDA classification (I, II, III). Entries include recall number, classification, status, product description, reason, recalling firm, distribution pattern, initiation and report dates (ISO) and voluntary or mandated status, plus counts by classification.

$0.01 per call USDC over x402 v2 on Base, Polygon, Arbitrum, Avalanche or Sei. No signup, no API key. Requests that fail or match nothing are not charged.

Endpoint

`q`	string	no	Drug name, brand or recalling firm text. Omit for all recent drug recalls. e.g. `metformin`

Example request

https://api.kit-rx.com/v1/rx/recalls?q=metformin&months=24&limit=5

Without payment the server answers 402 Payment Required with the price (10000 atomic USDC) in the PAYMENT-REQUIRED header. Any x402 v2 client pays and retries automatically. A request with no parameters runs this example.

curl -i "https://api.kit-rx.com/v1/rx/recalls?q=metformin&months=24&limit=5"
