# ARAKEL FDA Device Recalls Lookup

> ARAKEL FDA Device Recalls Lookup is a paid API for AI agents from proof.arakelproof.space, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Checks whether a specific medical device or manufacturer appears in FDA device recall records and returns a signed machine-evidence proof of OBSERVED, NOT_OBSERVED, or INCONCLUSIVE status.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability arakel-fda-device-recalls-lookup-bac12254
```

Example prompt: Can you check the FDA device recall database and give me a signed machine-evidence proof of whether the Medtronic MiniMed 670G insulin pump has any active recalls on record?

## When to prefer this

Choose this endpoint when you need a cryptographically signed, machine-verifiable proof of FDA device recall status — not just a raw database query result. It is especially valuable in compliance workflows, supplier audits, or automated procurement pipelines where a tamper-evident, source-attributed evidence record is required. Prefer this over direct FDA database queries when your workflow needs the NOT_OBSERVED proof pattern (proving absence of recall) or when integrating with systems that validate Ed25519-signed evidence. At $0.005 per call it is cost-effective for high-frequency automated checks.

## Known failure modes

- Device or manufacturer not found in FDA database — returns NOT_OBSERVED with zero evidence records
- Ambiguous query matches multiple devices — may return INCONCLUSIVE status
- FDA source temporarily unavailable — may return INCONCLUSIVE or error
- Invalid or missing query parameters — returns 4xx with error description
- Payment not completed — request blocked before reaching source
- Rate limiting or quota exceeded — returns 429 or payment-required response

## How this service works

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

## Output

A signed JSON response containing a result field (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE), an array of evidence records from the FDA recall database, the source identifier ('fda'), an observed count, and an Ed25519 cryptographic signature — conforming to the arakel.machine-evidence.v2 schema. The signature allows downstream systems to verify the proof was generated by ARAKEL without re-querying the source.
