  x-guidance: 'Every paid endpoint has a free twin at <path>/preview with the same parameters: it checks your input and shows what the paid answer contains, price and paid URL; use it before paying. Two kinds of endpoints, all GET with query parameters. (1) Compliance and onboarding, any country: /v1/invoice/check (before paying a supplier invoice: company check plus IBAN, VAT and sender email; verdict pass, review or hold), /v1/kyb/check (a European company in one call: register, directors, owners and parents screened for sanctions and PEP, VAT match, Peppol, website, Dutch bankruptcy), /v1/einvoice/peppol (is a company on Peppol e-invoicing), /v1/kyc/check (name, email, phone, vat in one call, one verdict), /v1/screen/bulk?names= (up to 100 names, metered per name), /v1/watch/new (30-day alerts), /v1/wallet/evidence (self-hosted wallet record), /v1/payee/check?url= (should my agent pay this x402 seller), free /v1/pay/guard?url=&pay_to=&amount_usd= (fast pre-payment check for x402 clients), free /v1/x402/sellers, /v1/eu/fx and /v1/eu/law, /v1/sanctions/screen?name= and /v1/sanctions/batch?names= (EU, UN, UK and US OFAC lists), /v1/email/verify?email=, /v1/phone/verify?phone=, /v1/eu/vat?vat=. (2) Dutch addresses, neighbourhoods and vehicles from government open data, in English. Address endpoints take postcode (e.g. 2517AS) + house_number, or q (free text). Area endpoints take postcode or a CBS neighbourhood code. Vehicle endpoints take licence_plate. Start cheap: /v1/address/lookup (validate + geocode) or /v1/neighbourhood; every paid response lists related follow-up calls with prices. Free: /v1/home/basic, /v1/vehicle/basic. Paid calls use x402 (USDC on Base or Solana); errors (4xx/5xx) are never charged.'
