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 data rows with field-value payloads, product metadata (slug and version), a provenance chain (license ID, source URL, observed timestamp), an Ed25519 cryptographic attestation signature, and a payment receipt with on-chain settlement reference.
Example use cases
Audit trail verification for compliance
“Get me the attested data record for ID 'rec-987xyz' as of 2025-01-01T00:00:00Z from Clink Forge — I need the provenance chain and Ed25519 signature for our compliance audit.”
Historical snapshot for dispute resolution
“Fetch the Clink Forge self-test data product for record ID 'dispute-442' as it existed on 2024-06-15T12:00:00Z — I need the signed payload and source URL to resolve a data discrepancy.”
Automated data integrity check in pipeline
“Retrieve the cryptographically signed data record for ID 'pipeline-001' as of 2026-03-10T08:00:00Z from Clink Forge so I can verify the attestation signature before processing downstream.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/forge-selftest-asofWhen to prefer
Choose this endpoint when you need a cryptographically attested, time-anchored data snapshot with full provenance chain for a specific record ID — particularly for audit, compliance, or data integrity workflows where Ed25519 signatures and on-chain payment receipts are required. Prefer this over generic REST data APIs when verifiable provenance and machine-readable attestation are non-negotiable requirements.
Side effects
- Missing or invalid 'id' query parameter returns a 400 error
- Missing or malformed 'as_of' datetime (must be ISO 8601) returns a 400 error
- Record ID not found for the given timestamp returns a 404 error
- Payment failure or insufficient USDC balance results in 402 Payment Required
- Invalid or expired x402 payment token returns an authentication error
- Rate limiting on the API may return 429 if called excessively
