How this service works
Penny Data: pay-per-call data for AI agents. UK company, LEI, postcode, carbon intensity, FX reference rate and food hygiene data as JSON, paid per call in USDC on Base with x402. No API key or account.
Output
A JSON object containing the company's legal name, company number, company type (e.g. ltd), active status, list of SIC codes, incorporation date, registered office address (including street, locality, postal code, country), accounts next due date, and confirmation statement next due date.
Example use cases
Due diligence on a UK supplier
“I'm about to sign a contract with a UK company — their Companies House number is 09876543. Can you check if they're still active, get their registered address, and tell me their SIC codes so I can verify what they actually do?”
Automated KYB verification pipeline
“We need to verify UK business 04567890 as part of our onboarding — pull their company status, incorporation date, registered office, and any SIC codes so we can run our know-your-business checks.”
Tracking accounts filing deadlines
“What's the next accounts due date for UK company number 00445790? I want to make sure I flag it in our compliance calendar before it lapses.”
Technical details
Endpoint
GEThttps://pennydatahq.com/api/company/%7Bnumber%7D?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need structured JSON company data for a UK-registered company by Companies House number, without setting up an API key or account. It is ideal for agent workflows requiring on-demand, pay-per-call lookups with micropayment via USDC on Base (x402 protocol). Prefer this over scraping Companies House directly or using heavier B2B data providers when you want low-friction, cost-proportional access for occasional or automated lookups.
Side effects
- Invalid or non-existent company number returns an error or empty response
- Dissolved or struck-off companies may return a non-active status rather than a lookup error
- Payment failure over x402 protocol results in a 402 response and no data returned
- Malformed company number format may cause a 400-level error
- Rate or quota issues are unlikely given pay-per-call model but network timeouts are possible
