TAIFOON[ The payout gateway · x402 ]
Pay a 402. Release on proof.
HTTP 402 is the price quote, USDC is the rail, and the superroot is the release condition. This page is the developer contract; the thesis lives on /x402.
01 //
CALL
Hit a paid skill with no payment attached. The answer is HTTP 402 — not an error, the offer: amount, asset, and where to pay.
02 //
PAY
Settle the quoted amount in USDC — Base (8453) or Solana. Machine-payable: no checkout, no card, no account manager.
03 //
RETRY
Repeat the call with the X-Payment header. The facilitator verifies the payment and the skill returns its deliverable.
04 //
ASSURE
For fund-moving work, capture is a pure function of proof: escrow releases only when the agreed event verifies against the anchored superroot.
