Look Up by Tx Hash

Find an order when all you have is an on-chain transaction hash: the buyer's pay-in transaction, or the payout transaction that landed in the recipient's wallet. Useful for reconciliation and support ("I sent this tx, where is my order?").

API Host: https://intentapiv4.rozo.ai/functions/v1

Endpoint: GET /payment-api/payments/check

No API key is required. The response is the same Payment object as GET /payment-api/payments/{paymentId}.

Parameters

Send exactly one of the hash parameters, or the address + memo pair.

Parameter	Matches	Search window
sourceTxHash	the pay-in transaction (from the payer)	last 90 days
destinationTxHash	the payout transaction (to the recipient)	last 90 days
txHash	either side (legacy; prefer the two above)	last 3 days
receiverAddress + receiverMemo	the deposit address and memo the order was created with	last 7 days

Sending more than one hash parameter returns 400 invalidRequest.
