Check payment details before you invoice.

For finance and onboarding teams

Batch validation report

Paste a list from your spreadsheet and get back one file that shows which IBANs, VAT numbers and domains are real. A wrong or fake one gets caught before you pay or invoice it, not after.

• Checks IBAN checksum, live EU VAT status and domain/mail delivery together, one row per record. That replaces three separate lookups in three separate tools.
• The EU VIES tool is free, and your bank checks IBAN account names for free on every transfer, but both work one lookup at a time. This report does up to 500 in a single file.
• No account, no API key, no monthly plan. report.csv and report.pdf by e-mail within one business day.

You send

Up to 500 values. Pasted cells, CSV or TXT. Names and headers are ignored.

You get

report.csv and report.pdf by e-mail

Delivery

Within one business day after payment

Price

€88 or 95 USDC excl. VAT (mini-check €17.50 / 19 USDC)

x402 endpoint, built for you

Describe an API you want to charge agents for. Forge builds and delivers it as a working x402 endpoint in 7 days: code, tests, docs and a deploy guide. You skip wiring up the payment logic yourself.

• You get more than a code file. Automated tests cover the payment flow itself, plus documentation and a step-by-step deploy guide. See the real layout below.
• Every build passes a security review and a QA review before it ships, the same two reviews Forge's own eu-validate endpoint passed before it went live.
• Fixed price, fixed scope, 7-day delivery. €139 or 150 USDC, once, not an hourly quote that can grow.

You send

What it should do, an example input and output, a price per call and your wallet address

You get

Source code with tests, documentation and a step-by-step deploy guide. The code is yours.

Delivery

Within 7 days after payment, by download link

For AI agents

eu-validate API

One call returns IBAN, VAT and domain status together, at $0.01 USDC per call. Your agent checks a counterparty before it invoices, pays out or onboards, without three separate integrations.

• IBAN checksum runs offline. VAT status is a live EU VIES lookup. Domain/mail is a live DNS lookup. All three combined in one JSON response.
• Unpaid requests get a 402 with the exact payment terms. Pay and retry. No account, no API key, no sign-up step first.
• The full contract is public before you spend a cent: llms.txt and openapi.json.
