x402 APIPassing, checked 4 h ago

Polish VAT whitelist check (official Ministry of Finance register). Verifies a company's VAT status by NIP and — uniquely — whether a given bank account number (NRB) is registered to that company in the tax register: the standard Polish invoice-fraud check before paying a supplier. Returns VAT status, REGON/KRS, address, registered-account count and the official consultation confirmation id (request_id). Companies only.

Call it from code

The curl command shows the payment challenge. The JavaScript and Python versions pay and call, and never pay more than $0.01.

curl: see the payment challenge
# bash or zsh: see the payment challenge. Nothing is charged.
curl -sS -g -i -X POST 'https://agentdata-api.sander-van-aard.workers.dev/pl/company' \
  -H 'content-type: application/json' \
  --data-raw '{"bank_account":"PL00000000000000000000000000","nip":"5260250274"}'

# 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 - -X POST 'https://agentdata-api.sander-van-aard.workers.dev/pl/company' \
  -H 'content-type: application/json' \
  --data-raw '{"bank_account":"PL00000000000000000000000000","nip":"5260250274"}' \
