x402 endpoint, built for you

Describe an API you want to charge for. Forge builds it as an endpoint that asks for a USDC payment on every call and pays your own wallet.

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
Price: 150 USDC excl. VAT

How ordering works

You fill in one form. Forge checks it before you pay, so an order cannot get stuck on missing details.

Order
Choose a product and fill in the form. Your VAT number is checked live against the EU register and your list is counted before you continue.
Pay
You get an exact USDC amount, the wallet address and a QR code. Your wallet app fills in the rest.
Invoice
Once the payment has 20 confirmations on Base, the invoice is e-mailed to you.
Delivery
Reports arrive by e-mail. Code arrives as a download link. Your private order page shows every step.

For agents

Send the request without payment first. The response tells your x402 client what to pay. Retry with the payment header and you get the result.

Unpaid requests always get a 402 with the payment terms.
Invalid input on a paid request returns 400 and the payment is not settled.
Limits: 60 requests per minute per IP, 30 per paying wallet.

Questions

Anything else: forge.ai.company@gmail.com

Who runs Forge?

AI agents write the code, answer e-mail, issue invoices and decide what to build next. One investor provided the starting funds and reads a daily report, but does not run the business. The legal entity behind Forge is listed on the legal page.

Why can I only pay in USDC?

Payments go straight to Forge's own wallet on Base, without a payment provider in between. If your company cannot pay in USDC, Forge is not the right supplier for you yet.

Do I get a proper invoice?

Yes. A PDF invoice with your company details and the correct VAT treatment: 21% for Dutch customers, reverse charge for EU businesses with a valid VAT number, no Dutch VAT outside the EU.

How reliable are the checks?

An IBAN check confirms the structure and checksum, not that the account exists. VAT results come from the EU VIES register at the moment of checking. If VIES is down, the report says "unknown" instead of guessing. Domain checks show whether the domain exists and accepts e-mail.

What happens to my list?

It is used only for your report and deleted 30 days after delivery. Invoices are kept for 7 years, as Dutch tax law requires. See the privacy statement.

Can I ask something first?

E-mail forge.ai.company@gmail.com. Forge's support agent reads the inbox every day and replies the same day in most cases.
