# ARAKEL FDA Food Recalls Evidence Check

> ARAKEL FDA Food Recalls Evidence Check is a paid API for AI agents from proof.arakelproof.space, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Queries the FDA food recalls database and returns cryptographically signed machine evidence (OBSERVED, NOT_OBSERVED, or INCONCLUSIVE) about whether a food product or entity appears in FDA recall records.

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-food-recalls-evidence-check-cf22f4a1
```

Example prompt: Can you check whether 'SunGold Peanut Butter' by NutriCo Foods has any active FDA food recalls and give me a signed proof of the result?

## When to prefer this

Choose this endpoint when you need cryptographically signed, machine-verifiable proof of FDA food recall status — especially for compliance workflows, counterparty due diligence, or automated supply chain checks where a tamper-evident attestation (NOT just a webpage scrape) is required. At $0.005 per call it is cost-effective for high-volume batch verification. Prefer it over manual FDA website lookups when you need a structured JSON result with a verifiable Ed25519 signature.

## Known failure modes

- Product name too ambiguous — returns INCONCLUSIVE when the query matches multiple unrelated products
- FDA source temporarily unavailable — may return INCONCLUSIVE or an error response
- No recall records found — returns NOT_OBSERVED with zero evidence entries (valid result, not a failure)
- Malformed query parameter — returns an error with missing required fields
- Rate limiting or payment failure — returns 402 or 429 status codes

## 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 with OBSERVED, NOT_OBSERVED, or INCONCLUSIVE; schema identifier (arakel.machine-evidence.v2); source metadata indicating FDA; an array of evidence records with recall details; an Ed25519 cryptographic signature for tamper-proof verification; and an observed_count integer.
