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; product metadata (slug, version); a provenance chain (license ID, source URL, observed timestamp); an Ed25519 cryptographic attestation (algorithm + base64 signature); and a payment receipt with an on-chain settlement reference.
Example use cases
Verify x402 payment pipeline end-to-end
“Can you run the Clink Forge self-test product with ID 'forge-selftest' and confirm that the payment settled and the Ed25519 attestation came back valid?”
Confirm provenance chain before production use
“Before I start using Clink Forge data products in my pipeline, fetch the self-test record and show me the license ID, source URL, and observation timestamp in the provenance chain.”
Debug micropayment integration in dev environment
“I'm setting up my agent to buy data products over x402 — can you make a test call to the Clink Forge self-test endpoint with ID 'forge-selftest' and show me the full response including the settlement reference?”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/forge-selftestWhen to prefer
Use this endpoint when you need to verify that the Clink Forge x402 micropayment and cryptographic attestation pipeline is functioning correctly, or when you want a low-cost ($0.001 USDC) reference call to validate your payment integration before calling production data products. Prefer this over general data product endpoints when the goal is infrastructure testing or provenance verification rather than real data retrieval.
Side effects
- Missing or invalid 'id' query parameter returns a 400 error
- Payment failure or insufficient USDC balance causes a 402 Payment Required with payment instructions
- Invalid or expired x402 payment token results in payment rejection
- ID string exceeding 40 characters is rejected by schema validation
- Server-side attestation failure may return an error without a signed payload
- Network timeout or upstream unavailability returns a 5xx error
