How this service works
Check a UK company by resolving its Companies House identity and verifying current legal-status and insolvency observations in one paid call. Use before onboarding or contracting. It reports filing limits and does not promise universal good standing.
Output
The endpoint returns the resolved Companies House identity for the UK company (matched by number, name, or postal code), its current legal status (e.g. active, dissolved, struck off), and any insolvency observations (e.g. liquidation, administration, receivership). It also notes filing limits and scope caveats, clarifying that the result does not constitute a universal good-standing certificate.
Example use cases
Supplier onboarding due diligence
“We're about to onboard a new UK supplier called Northgate Logistics Ltd, company number 09876543 — can you verify their Companies House identity and check whether they have any active insolvency observations before we proceed?”
Pre-contract vendor screening
“I need to sign a services agreement with a UK company called Brightfield Consulting, company number 07654321 — please check their legal status on Companies House and let me know if there are any insolvency concerns I should know about.”
Customer credit risk check
“A new UK customer, Harlow Manufacturing Ltd (company number 11223344), wants to open a credit account with us — can you do a Companies House check to confirm they're active and not in insolvency before we approve it?”
Technical details
Endpoint
POSThttps://cdo-production.up.railway.app/v1/gb/solutions/company-checkWhen to prefer
Choose this endpoint when you need a fast, single-call check of a UK company's Companies House identity and insolvency status before onboarding a supplier, signing a contract, or extending credit. It is purpose-built for UK entities and uses Companies House as its authoritative source. Prefer it over generic company data APIs when you need insolvency observations specifically and want a pay-per-call model with no subscription. Not suited for non-UK companies (use the Brazilian company endpoints on the same platform for LATAM entities) or for full financial credit scoring.
Side effects
- Company not found — no Companies House record matches the provided number, name, or postal code
- Invalid company number format — input does not match the required pattern (6–8 digits, optional 2-letter prefix)
- Ambiguous match — company name resolves to multiple entities without a disambiguating number or postal code
- Insolvency data unavailable — Companies House filing gaps may result in incomplete insolvency observations
- Payment failure — the $0.04 USDC charge via x402 is declined or wallet has insufficient funds
- Idempotency key collision — a mismatched idempotency key resubmission may return a cached or rejected result
