CelerAPI

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. Use this first when the registration identifier is unknown; a country_hint is recommended and omission preserves the GB default. Other country codes are unsupported.
