How this service works
Resolve a company name, website domain, registry number, LEI or VAT number to its official legal entity: registry, registry number, legal form, status, address, industry codes, size where published and LEI. Searches national registers (Norway, Finland, Czechia, Slovakia, France, UK, Latvia, Estonia on the API and MCP; Poland by KRS number; Brazil by CNPJ, Singapore, Canadian federal corporations on the API and MCP) and GLEIF, scores the match and links every record to its…
Output
Returns a matched flag, the best matching company record (with name, LEI, registry ID, address, legal form, industry codes, employee count, website, incorporation date, match score, match reason, source registry, and licence), a list of ranked candidate matches, and metadata including the data sources used and query timestamp.
Example use cases
KYC check for new vendor
“I need to verify that 'Acme Solutions s.r.o.' is a legitimately registered company in Czech Republic — can you pull their official registry record including their registration number and legal status?”
Identify company from domain name
“I found a company at the domain 'equinor.com' but I need their official legal name, LEI, and country of registration — can you resolve that for me?”
Batch supplier verification
“I have a list of company names in Finland and Norway — can you look up each one in the official business registers and return their registry IDs, active status, and legal forms?”
Technical details
Endpoint
GEThttps://api.ambolt.dev/v1/entity-resolve?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to resolve a company name, domain, VAT, or registry number to an authoritative official record from government business registers. Ideal for KYC, due diligence, supplier verification, and enriching company data with LEIs and legal metadata. Prefer this over generic web search when you need structured, official register data with licensing information.
Side effects
- No match found for ambiguous or misspelled company names (matched: false)
- Country not yet supported in covered registers (NO, FI, CZ, SK, FR, GB, PL only)
- Query string too long (over 200 characters)
- Rate limiting or payment failure for x402 micropayment
- Registry data may be stale or incomplete for recently incorporated companies
