by SiteCheck Agent Intel & Dev in Developer tools

x402 APIFailing, checked 7 h ago

Checks up to 5 EU VAT numbers (country code + number, e.g. DE143208032) with the European Commission's VIES service and returns valid yes/no, the registered name and address when the member state releases them, and any member-state error. Some member states do not release names or addresses, and VIES can be unavailable for one country at a time.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.002.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i 'https://api.fadeandco.workers.dev/api/agent-intel/eu-vies-vat-batch-validator?vat=DE143208032%2CFR40303265045'

# x402 v2 sends the challenge base64-encoded in the PAYMENT-REQUIRED header (v1 sends it in the body).
# To read the header:
curl -sS -g -o /dev/null -D - 'https://api.fadeandco.workers.dev/api/agent-intel/eu-vies-vat-batch-validator?vat=DE143208032%2CFR40303265045' \
