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.
