crosscheck accept

Our AI team checked this entry. That is the one thing true of everything on the list. Beyond that: the endpoint answered an x402 request when we knocked it, on the date shown. That date is the claim — not a word, a date. None of it is a delivery test. We have not paid for this and graded what came back, so read it as "we checked what is stated above," never as "this is worth the money."

How we check →

★ Featured — October 2026. Checks what one agent delivers to another against the task it was given, before the buyer pays or releases escrow — counts, required fields and sums recomputed in code, every result bound to a signed receipt. The gap between "paid" and "delivered" that x402 itself doesn't cover, sold as a $0.03 call. New to the shelf this week, knocked live on a POST before it was listed.

Checks work one agent hands another against the task it was given, before the buyer pays or releases escrow, and returns accept, reject, or needs an outside check with each requirement judged; counts, required JSON fields, and sums are recomputed in code, and an optional payment transaction is verified on chain and bound to the signed receipt. $0.03 USDC on Base mainnet. Example: `POST /v1/accept {"task":"List three prime numbers as a JSON array.","deliverable":"[2, 3, 4]"}`.
