## 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-self-test-bulk-product-90355249
```

Example prompt: Fetch a batch of attested data rows from Clink Forge's forge-selftest-bulk product — I need the full provenance chain including license ID, source URL, and Ed25519 signature, paid per-call in USDC.

## When to prefer this

Choose this endpoint when you need bulk data records with cryptographic provenance and attestation included in the response, and you are operating in an x402 micropayment context where per-call USDC settlement is acceptable. Prefer it over unauthenticated data sources when verifiable data lineage and license traceability are required.

## Known failure modes

- 402 Payment Required if x402 payment header is missing or insufficient
- Invalid or expired payment token causes rejection
- Malformed request parameters return 400 Bad Request
- Network timeout if upstream data source is unavailable
- Rate limiting if too many calls in a short period

## 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 object containing: an array of data rows (each with a payload and record_id), a product descriptor (slug and version), a provenance chain (license_id, source_url, observed_at timestamp), a cryptographic attestation (Ed25519 algorithm and base64 signature), and a payment receipt (settlement_ref transaction hash).
