## 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 clink-forge-fda-recall-state-summary-9fe18180
```

Example prompt: Pull the FDA recall state summary from Clink Forge — I need the latest breakdown of recalls by state with cryptographic provenance so I can verify the data source.

## When to prefer this

Choose this endpoint when you need FDA recall data at the state level AND require cryptographic provenance (Ed25519 attestation) to prove data integrity and origin — ideal for compliance, audit trails, or machine-to-machine workflows where trust in data provenance is mandatory. Prefer over raw FDA API scraping when you need a signed, pay-per-call data product with settlement receipts.

## Known failure modes

- Payment not included or invalid x402 header — 402 Payment Required
- Insufficient USDC balance for micropayment — payment failure
- Endpoint returns stale data if upstream FDA source has not been recently observed
- Schema stub suggests input parameters may not be fully documented, leading to uncertain query construction
- Network timeout or upstream FDA data pipeline unavailability

## How this service works

Pay per call over x402. USDC on Base, no account, no API key. 28 government-sourced data products at $0.001–$0.05 per call, every response signed and provenance-chained.

## Output

A JSON response containing an array of data rows (each with a payload and record ID), product metadata (slug and version), a provenance object (license ID 'US-GOV-PD', source URL, and observation timestamp), an Ed25519 cryptographic signature attesting data integrity, and a blockchain settlement reference from the x402 payment receipt.
