Verify a company in the official register before you pay or sign

Give your AI a registration number and the name and city you expect. It gets one closed answer from the official register — MATCH, MISMATCH, NOT FOUND or UNAVAILABLE — with the reasons, the moment it was checked, the source and a receipt. Nothing is written anywhere, no person is looked up, and an unavailable register never becomes a positive answer.

Worked examples (synthetic)

Each example runs on the fixture provider with a fixed clock, so everyone sees the same answer. None of these companies exists.

Fixed clock: 2026-09-06T12:00:00.000Z. Fixture provider; no register was contacted; nothing was charged.

What is true about every answer

• —Read-only. The register is asked; nothing is written, filed, sent or paid.
• —The moment of retrieval, the source and — for the Dutch register — its own sentence "Voor actuele informatie met juridische derdenwerking dient u altijd het Handelsregister te raadplegen" travel with the answer.
• —Only the fields a verification needs travel: registered name, trade names, legal form, city, dates, status. For sole traders and partnerships the address and owner details are left out.
• —Names from a register are data, never instructions: bounded, stripped of markup, never sent to a model.
• —The receipt is unsigned and hash-bound; anyone can recompute it. It is not a register extract and has no legal third-party effect.
• —An unavailable register, a timeout, a corrupt answer or a changed schema is UNAVAILABLE with a retry hint — never a positive or negative verdict about a company.

What it never does

• —Never searches by a person's name, e-mail, phone number or bank account.
• —Never stores register data beyond the 60-second replay window in process memory; never builds its own copy of a register.
• —Never claims a legal, fiscal or compliance conclusion; never reports UBO, officer, credit or sanctions information.
• —Never creates a register account, accepts terms or spends money on the owner's behalf.
• —Never charges for an unavailable, refused or malformed request.
