How this service works
UK Companies House company profile by company number, or search by name: name, status, type, incorporation and cessation dates, registered office, SIC codes, accounts and confirmation-statement dates, charges and insolvency flags. Cached; an uncached company is queued.
Output
A JSON object containing the company's official name, type (e.g. plc, ltd), active status, registered address (line1, line2, postalCode), SIC codes, jurisdiction (e.g. england-wales), company number, date of creation, date of cessation (if any), next accounts due date, last accounts made up to, next confirmation statement due date, and last confirmation statement made up to.
Example use cases
Verify supplier company registration
“I need to verify that Rolls-Royce Holdings is a legitimately registered UK company — can you pull their Companies House record including their company number, status, and registered address?”
Due diligence on a UK counterparty
“We're about to sign a contract with a UK firm and I need their official registration details from Companies House — look up company number 00102498 and tell me their type, jurisdiction, and whether they're still active.”
Check upcoming filing deadlines
“Can you find the Companies House record for Vodafone Group PLC and tell me when their next confirmation statement and accounts are due so we can flag any upcoming compliance dates?”

Endpoint
GEThttps://api.maxwellinternational.ai/v1/gov/gb/companies?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official, structured UK company data sourced from Companies House, particularly for due diligence, supplier verification, compliance checks, or enriching business records with authoritative registration details. Prefer this over generic web search when you need machine-readable structured fields like SIC codes, filing dates, and company status.
Side effects
- Company not found — returns error or empty result if company number or name does not match any record
- Invalid query parameters — malformed request may return 400 or empty response
- Rate limiting or payment failure — x402 payment not processed correctly results in 402 error
- Domain or service unavailability — the domain is listed for sale, raising reliability concerns about long-term availability
