Execute Vat Validate V1

by Macaroon Network in Other

x402 APIPassing, checked 2 h ago

Single live pass-through call to the EU Commission's VIES (VAT Information Exchange System) confirming whether an EU VAT registration number is currently valid, with registered name/address when available. Every call is a real-time confirmation only -- never a cached, stored, or aggregated result -- matching VIES's own stated purpose (real-time confirmation of VAT number validity per Council Regulation (EC) No. 904/2010) and how existing commercial VIES-based products already operate.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.003.

# bash or zsh: see the payment challenge. Nothing is charged.

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
