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
Returns a JSON object containing one or more data rows with payload fields, the product slug and version, a provenance block (license ID, source URL, observed timestamp), an Ed25519 cryptographic attestation signature, and a payment receipt with settlement reference — enabling full auditability of the data's origin and integrity.
Example use cases
Verify country data for compliance pipeline
“I need cryptographically attested World Bank country data for 'DE' — fetch it and show me the provenance details and attestation signature so I can store it in our compliance record.”
Enrich dataset with sovereign country metadata
“Pull the World Bank country entry for 'IN' with its full provenance chain so I can enrich our dataset with verified, audit-ready country metadata.”
Spot-check country record integrity
“Fetch the Clink Forge country lookup for 'BR' and tell me the source URL, license, and whether the attestation checks out — I want to make sure this data is trustworthy before using it.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/wb-country-lookupWhen to prefer
Choose this endpoint when you need machine-verifiable, cryptographically attested country data with a full provenance chain — especially in compliance, audit, or trust-critical pipelines where raw data alone is insufficient. Prefer it over open REST country APIs when your agent or downstream system needs to prove data origin, licensing, and integrity via a digital signature. The per-call x402 micropayment model makes it suitable for on-demand, low-volume lookups without subscription overhead.
Side effects
- Missing or invalid 'id' query parameter returns a 400-level error
- Country ID exceeding 8 characters is rejected by schema validation
- Payment not processed (x402 flow failure) results in 402 Payment Required
- Unknown or unsupported country ID may return empty rows
- Network or upstream provider unavailability causes 5xx errors
