One-call drug situational awareness. Give a drug name (resolved to a canonical RxCUI via NIH RxNorm), or an exact rxcui or ndc you already hold, and get back: whether it is currently in FDA shortage, any open or recent FDA recalls, and FDA NDC-directory metadata (labeler, DEA schedule, pharmaceutical class, marketing status). Returns a resolved identity block plus hasCurrentShortage / hasOpenRecall booleans and one found/error block per source (shortages, ndc, recalls). Composition of NIH RxNorm + OpenFDA drug-shortages, NDC directory, and recall enforcement — all free, public-domain US government data; each source degrades independently. Point-in-time public records, not medical advice. Use for pharmacy/supply-chain triage, prescribing-support agents, and verifying a drug is real, scheduled, and available before acting.
/api/medical/drug-statusPAYMENT-SIGNATURE.The drug status API is a pay-per-call medical endpoint built for AI agents and autonomous software. One-call drug situational awareness.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in drug status data source for an agent tool-use loop, an MCP host, or a backend that needs medical data on demand without onboarding to yet another vendor portal.
