How this service works

Machine-verifiable official-source evidence with free preflight and x402 USDC payments on Base.

Output

A JSON object containing a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), the ARAKEL machine-evidence schema version, the source identifier (fda), an array of matching evidence records, and an Ed25519 cryptographic signature attesting to the proof's authenticity.

Example use cases

Pharmacy compliance recall audit

“I need a verified proof of whether metformin 500mg tablets from Amneal Pharmaceuticals have any FDA recalls on record — can you pull a signed machine-evidence result I can attach to our compliance report?”

Drug supply chain due diligence

“Before we finalize this pharmaceutical procurement contract, can you get me an FDA drug recall check on the lot we're buying — I need a cryptographically signed NOT_OBSERVED or OBSERVED proof to include in the dossier?”

Consumer drug safety verification

“I bought some OTC ibuprofen from a third-party seller and I'm worried it might be recalled — can you check the FDA drug recall database and give me a signed result showing whether it's been flagged?”

Endpoint

GEThttps://proof.arakelproof.space/v1/fda-drug-recalls

When to prefer

Choose this endpoint when you need a cryptographically signed, machine-verifiable attestation of FDA drug recall status — not just a raw database query. It is ideal for compliance workflows, supply chain audits, or counterparty due diligence where a NOT_OBSERVED proof (with Ed25519 signature) must be produced as evidence. Prefer this over direct FDA API access when you need structured, signed proofs consumable by downstream agents or smart contracts.

Side effects

Drug or NDC not found in FDA recall database — returns NOT_OBSERVED with empty evidence array
Ambiguous query returns INCONCLUSIVE result
FDA source temporarily unavailable — may return error or INCONCLUSIVE
Invalid or missing query parameters — returns HTTP 400
Payment not received or underpaid — returns HTTP 402 (x402 payment required)
Rate limiting or quota exceeded — returns HTTP 429
