Compliance KYB ownership check
“For our KYB process, I need to verify who owns and controls the UK company with registration number 04567890 — can you get the persons with significant control from Companies House?”
Investigative research on corporate structure

Technical details
Endpoint
GEThttps://www.celerapi.com/v1/company/%7BcompanyNumber%7D/owners?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need live, structured beneficial ownership data for a UK-registered company directly from the authoritative Companies House registry. Prefer this over scraping or third-party aggregators when accuracy, freshness, and provenance traceability are required — particularly for KYB compliance, M&A due diligence, or investigative research. Best suited for per-request lookups where you have a specific UK company registration number.
Side effects
- Invalid or non-existent company number returns an error or empty data object
- Company has no filed ownership data (e.g. newly registered or exempt entity) may return empty owners list with warnings
- Rate limiting or payment failure returns a 402 Payment Required response
- Malformed company number format may return a validation error
- Companies House API downtime may result in stale or unavailable data
