How this service works
API and MCP servers that let AI agents and apps check people, companies, Dutch addresses and cars against official records: sanctions and PEP lists, 10 company registers, Dutch property, rent and RDW vehicle data. From $0.001 per call.
Output
A JSON object containing a verdict (pass/fail), company details (name, status, registry ID, legal form, address, incorporation date, country, registry name), per-check results for sanctions screening, VAT validation, domain flags, insolvency status, a human-readable summary, and a list of other possible company matches found during the search.
Example use cases
Onboarding a new B2B supplier
“Before we onboard Signify NV as a supplier, can you verify them against official company registers and sanctions lists? Their country is NL and their domain is signify.com.”
Screening a potential investment target
“I'm considering investing in a French company called Société Générale — can you check their SIREN against official records and see if they appear on any EU, UN, UK, or US sanctions lists?”
Validating a VAT number for invoicing
“A new client gave me VAT number IE6388047V — can you check it against VIES and confirm it matches the registered company name and that the company is active?”
Technical details
Endpoint
GEThttps://factline.dev/v1/kyb/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a structured, official-record-backed KYB (Know Your Business) check across multiple European company registers simultaneously, combined with sanctions screening, VAT validation, and insolvency checks in a single call. It is especially strong for European companies (Netherlands, UK, Ireland, France, Norway, Finland, Czech Republic, Slovakia, Poland, Estonia) and for workflows requiring a pass/fail compliance verdict with audit-ready source attribution. Prefer this over building manual register lookups when you need multi-jurisdiction coverage and sanctions screening bundled together at low per-call cost.
Side effects
- Company not found in any supported register — returns empty or no match
- Ambiguous company name with multiple matches — returns other_matches array requiring disambiguation
- Unsupported country or registry — check not performed for that register
- VAT number invalid or not found in VIES — vat check returns invalid status
- Domain not provided — domain check returns 'not requested' placeholder
- Rate limit or payment failure — HTTP 402 or 429 response
- Malformed input parameters — HTTP 400 with validation error
