The receipt is read on chain; the transfer must be within the last 150 blocks, each hash pays once, and only the caller that received that challenge can redeem it. Optionally also send X-Payment-Challenge-Signature: the sending wallet's signature over the challenge message (layout on the x402 protocol page). It is optional today and will become required; signing makes your hash unredeemable by anyone else. A redemption sent right after mining can be refused with errorCode settlement_not_yet_visible while our node catches up; the hash is not consumed, so wait for Retry-After and send the same request again.",
