How this service works
Search authoritative company registries by company name to resolve candidate legal entities and registration identifiers. Currently supports the United Kingdom (GB) and Norway (NO), with expanding jurisdiction coverage. Results are public-register evidence, not a KYC or KYB compliance determination.
Output
Returns a structured response including success status, completeness flag, an array of matching company records from UK Companies House, entity ID, provenance metadata describing the data source, and any warnings. The data field contains the actual company search results.
Example use cases
Verify a UK supplier's registration
“I need to check if 'Meridian Supply Chain Ltd' is actually a registered UK company — can you search Companies House for it and tell me what you find?”
Find company number for contract
“I'm drafting a contract and need the official Companies House registration details for 'Blue Horizon Consulting Ltd' — can you look it up?”
Due diligence on a potential partner
“We're considering partnering with a firm called 'Apex Digital Solutions' in the UK — can you search Companies House to see if they're registered and pull up their company info?”
