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 company record fields, the product identifier, row count, a provenance chain (hash, authority name, source government URL, observation timestamp), a cryptographic attestation (signature, result digest, signing key ID), and a payment receipt (USD amount, on-chain settlement reference). Every response is signed by Clink Forge for verifiable data integrity.
Example use cases
KYB check for onboarding a UK vendor
“I need to verify that the UK company with registration number 04152218 is a legitimately registered business before we onboard them — can you pull their official government record and confirm it?”
Due diligence on a UK acquisition target
“We're considering acquiring a UK company with registration number 07841138 — can you fetch their official Companies House data with a provenance chain so our legal team can see where the information came from?”
Automated compliance enrichment pipeline
“For each UK company number in this list, look up the official government registration record and include the cryptographic attestation so we can store proof of data source in our compliance system — start with 00445790.”
Technical details
Endpoint
GEThttps://api.clinkforge.com/v1/p/uk-company-lookupWhen to prefer
Choose this endpoint when you need official UK company registration data with cryptographic proof of provenance — ideal for KYB/KYC compliance, due diligence, legal workflows, or any automated pipeline where you need to prove the data came from a government source. It requires no account or API key, only a USDC wallet on Base, making it suitable for autonomous agents. Prefer this over scraping Companies House directly or using unofficial aggregators when verifiability and auditability of the data source are required.
Side effects
- Invalid or missing company ID (id param absent or malformed) — returns 400 bad request
- Company number not found in registry — returns empty data array or 404
- Payment failure or insufficient USDC balance — x402 payment required response
- Company number exceeds 12-character max length — schema validation error
- Network or upstream government data source unavailable — 503 or timeout
- Attestation signing failure — server-side error response
