BelgiumVatChecker
.NET Web API that validates Belgian and EU VAT numbers using the VIES service.
What it does
.NET Web API that checks a Belgian VAT number's format and modulo-97 checksum and validates any EU VAT number against VIES, returning validity, name and address as JSON, plus a VIES status endpoint. It runs with the .NET SDK or in Docker. The README says a valid result only confirms the number exists in VIES, not the company's status, and VIES is sometimes down for maintenance.
