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: an array of data rows with payload fields and record IDs, product metadata (slug and version), a provenance chain (license ID, source URL, observation timestamp), an Ed25519 cryptographic attestation signature, and a payment receipt with an on-chain settlement reference. This allows callers to verify data authenticity and trace its origin to the authoritative government source.
Example use cases
Compliance audit with provenance trail
“Look up federal registry document ID 'EO-2023-45678' for me — I need the actual record data plus the cryptographic attestation and source URL so I can prove to our compliance team exactly where it came from.”
Regulatory research for legal team
“Fetch the federal registry record 'CFR-2025-00987' and tell me what fields are in it, what license it's under, and when it was observed — our lawyers need the full provenance chain.”
Automated government data pipeline
“Retrieve federal registry document 'FR-2024-77301' including the Ed25519 signature and settlement receipt — we're ingesting verified gov records into our database and need the attestation to be machine-readable.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/fedreg-doc-lookupWhen to prefer
Choose this endpoint when you need a federal registry document by a known ID and require cryptographic provenance attestation alongside the data — not just raw data retrieval. Ideal for compliance, legal, and audit workflows where chain-of-custody verification matters. Prefer this over general web scraping or unverified government data APIs when you need a machine-readable Ed25519 signature and on-chain payment receipt as proof of data integrity. The per-call micropayment model makes it cost-effective for low-volume, on-demand lookups rather than bulk batch processing.
Side effects
- Missing or invalid 'id' query parameter returns a 400 or validation error
- Unknown document ID returns empty rows array or 404
- Payment failure via x402 protocol (insufficient funds, invalid payment) blocks the request
- ID exceeding 40 characters is rejected by schema validation
- Service unavailability or upstream federal data source outage results in 5xx error
- Stale or uncached records may return older observation timestamps
