The same tools are available as ordinary HTTP endpoints. See the machine-readable catalogue for schemas and examples.
curl 'https://api.companyverify.uk/v1/uk/company/search?q=TESCO&limit=3'
Search the UK Companies House register by name or number. Returns candidate companies with number, status, type, incorporation date and registered address, with provenance. Primary source with retrieval timestamp; cached for up to 24 hours.
readyFull Companies House profile for a company number: status, SIC codes, registered office, accounts and confirmation statement dates, plus the first page of officers (up to 35), with explicit total/coverage metadata. Primary source, cached for up to 24 hours, provenance attached.
readyResolve a legal entity to its Legal Entity Identifier via the GLEIF API, by LEI or by name. Returns LEI, legal name, jurisdiction, status and registration dates. CC0 source data, provenance attached.
readyScreen a person or entity name against sanctions lists loaded directly from primary government sources (configurable: OFAC SDN and consolidated, the UK Sanctions List). Returns match verdict, candidate hits with scores, list versions and retrieval timestamps. Not a PEP or adverse-media screen.
readyCompare two company references using supplied company-number/LEI equality and normalised name similarity. When one reference has a UK company number and the other only a name, optionally corroborates against Companies House. LEIs are compared as supplied, not validated against GLEIF by this tool. Returns a verdict, heuristic confidence and signal provenance.
readyUse find_capability and request_data from your agent. Planned capabilities are clearly labelled free probes and return not_covered.
Name similarity is experimental. A match is a signal to investigate, not proof of identity or a compliance decision.
