{"jsonrpc":"2.0","id":1,"method":"tools/list"}check_vat — Validate an EU VAT number against VIES. Returns whether the number is a valid/registered EU VAT registration, plus the registered name and address when the member state publishes them (many states return "---" or empty even for valid numbers). A false result means not registered/invalid. If the national service is temporarily down, userError is MS_UNAVAILABLE/MS_MAX_CONCURRENT_REQ etc. — treat that as "could not check", not "invalid".service_status — List all EU member states and whether each national VAT-checking service is currently Available or Unavailable, plus overall VIES (VoW) availability. Use this before/after a failed check_vat to tell a temporary national outage apart from a genuinely invalid VAT number.Code samples (curl / TypeScript / one-click client install), schemas, and the live playground are on the pack page:
