Example use cases
Due diligence on a UK supplier
“I'm about to sign a contract with a UK company — their number is 07495895. Can you pull their last 20 Companies House filings so I can check they've been keeping up with statutory obligations?”
Investor research on a UK firm
“I'm looking at investing in a UK startup, company number 11223344. Can you fetch their recent Companies House filings so I can see their filing history and whether they're compliant?”
Monitoring a competitor's filings
“Can you get the latest 15 Companies House filings for company number 00445790? I want to track what documents they've been submitting recently.”
Technical details
Endpoint
GEThttps://www.celerapi.com/v1/company/%7BcompanyNumber%7D/filings?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the filing history of a specific UK company and already have the company number (e.g. retrieved from a prior company search). It's ideal for due diligence, compliance checking, investor research, or monitoring a company's regulatory submissions. Prefer this over general web scraping when you need structured, live data directly from the authoritative UK Companies House registry.
Side effects
- Invalid company number format (must be 8 alphanumeric characters) returns a validation error
- Company number not found in Companies House registry returns no data or an empty result
- Payment failure via x402 protocol results in 402 response and no data returned
- Rate limiting or upstream Companies House API unavailability may cause timeouts or errors
- Requesting a limit outside the 1–100 range returns a validation error
