Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| settlement_tx | string | yes | Solana transaction signature only. No claim body is accepted. Verifies that signature against x402_payment_receipts and a freshly fetched finalized transaction: match requires the only positive USDC balance change to credit that row's merchant for that row's amount, and the only USDC debit to be that amount from that row's payer, which match returns as payer. Returns match, mismatch, or unknown. Unknown does not block payment. |
