How this service works
Pay-per-call APIs for AI agents — x402 protocol, USDC on Base, no account needed.
Output
Returns a JSON object containing the company's registered name (e.g. 'TESCO PLC'), its current status (e.g. 'active'), and the company number used for the lookup. Useful for verifying corporate identity and registration status against the UK Companies House registry.
Example use cases
Due diligence on a UK supplier
“I'm about to sign a contract with a supplier who gave me company number 09876543 — can you check what their registered company name is and whether they're still active on Companies House?”
Verifying a business before payment
“Before I send an invoice, can you confirm that UK company number 00445790 is registered as TESCO PLC and is currently active?”
Automated KYC enrichment
“I have a list of UK company numbers from new business customers — can you look up company number 12345678 and return its official registered name and status so I can cross-check their application?”
Technical details
Endpoint
GEThttps://x402-farm.vercel.app/v1/uk/companyWhen to prefer
Use this endpoint when you need to verify or enrich UK company identity using a Companies House registration number, especially in due diligence, KYC, supplier verification, or compliance workflows. It requires no account setup and charges per call via USDC on Base, making it ideal for low-volume or agent-driven lookups without API key management overhead. Prefer this over full Companies House API integration when you only need name and status fields and want frictionless pay-per-use access.
Side effects
- Invalid or non-existent company number returns an error or empty result
- Company number formatted incorrectly (e.g. missing leading zeros) may not match
- Dissolved or struck-off companies may return a non-active status rather than an error
- Payment failure via x402/USDC results in a 402 response before data is returned
- Rate limits or network issues may cause transient failures
