Papaya — payment rail for the AI economy Protocol: x402 / settles in USDC

Robots have MNEY now. Get your cut.

Papaya is a vending machine for the internet — put your API, data, or tool behind a slot and every AI agent that wants it pays you per use. No accounts. No invoices. No chargebacks. Coin in, value out.

Try the protocol

One request.
One coin. One second.

This is the entire customer journey for an AI agent buying your data. No signup form. No API key email. No card on file.

The first request hits a wall — 402 Payment Required. The agent's wallet signs a digital-dollar payment and retries. Verified on-chain, then served. If the wallet's empty, nothing opens.

That's why there's no fraud story here: the payment is the trust.

For businesses

B/1

New revenue, zero effort

Agents already hit your stuff. Today you earn nothing. With Papaya, every visit can pay.

B/2

No billing to build

No subscriptions to run, no invoices to chase. Papaya is the whole register.

B/3

Money's guaranteed

The agent pays before it gets anything. Empty wallet, closed gate. No chargebacks, ever.

B/4

Paid straight to your wallet

Settles in USDC — digital dollars, 1:1 backed. It lands in a wallet only you control; Papaya never holds your money. Cash out whenever you like.

Unpaid → 402 with the price. Paid → 200 with the goods. That's the whole contract.

No bot detection

Everyone hits the same wall. A scraper either becomes a customer or gets nothing — both are wins.
