How It Works

1

Discovery

AI agent calls your API and receives a 402 Payment Required response.

Agent → Provider
2

Quote

Agent requests a payment quote from NONAGON LINK and receives a nonce.

Agent → NONAGON LINK
3

Transfer

Agent sends USDC on Solana with the nonce as a memo.

Agent → Solana
4

Authorize

NONAGON LINK verifies the transaction and issues an access token.

Access

Agent uses the token to access your API — you get paid per call.

Agent → Provider
6

Settlement

Request a payout anytime — USDC is converted to USD and wired to your bank account.
