How this service works

$0.001 OFAC destination-wallet preflight for autonomous agents, plus machine-verifiable official-source evidence over x402 USDC on Base.

Output

A JSON object with a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), an array of FDA enforcement evidence records, the source identifier (fda), an Ed25519 cryptographic signature for machine verification, the schema version (arakel.machine-evidence.v2), and a count of observed recalls.

Example use cases

When to prefer

Choose this endpoint when you need machine-verifiable, cryptographically signed evidence of FDA recall status — not just a raw data dump. It is best for autonomous agents that need to prove compliance, audit trails, or tamper-evident recall monitoring over a specific date range. Prefer it over direct openFDA queries when signature verification and structured evidence schemas (arakel.machine-evidence.v2) are required.

Side effects

Query string missing — returns 400 validation error
Date range too broad or malformed datetime — returns 400
No recalls found for query returns result: NOT_OBSERVED (not an error)
FDA openFDA source unavailable — may return INCONCLUSIVE
Payment not completed via x402 — returns 402 with payment requirements
Rate limits or network errors return 5xx
