> MadhouseWallet Confirm Transfer is a paid API for AI agents from try.madhousewallet.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).

Confirms a funded USDC transfer by submitting the on-chain transaction hash, triggering the cross-border payout to proceed.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability try-madhousewallet-com-96cf58a5 -d '<json body>'
```

Example prompt: I already sent the USDC deposit — please confirm transfer TXF-abc123 using the on-chain transaction hash 0xdef456...789 so the payout gets released.

## When to prefer this

Use this endpoint after successfully sending USDC to the deposit_address returned by the create-transfer endpoint. This is the required second step to finalize any cross-border payout initiated via MadhouseWallet — without it, the payout remains pending indefinitely. Choose this when you have both the transfer_id and the on-chain tx_hash of your USDC deposit ready.

## Known failure modes

- Invalid or unrecognized transfer_id returns a 404 or error
- Incorrect or malformed tx_hash causes validation failure
- Transaction not yet confirmed on-chain leads to rejection
- Duplicate submission of same tx_hash is accepted idempotently
- Transfer already in a final state (completed/failed) may return an error
- Insufficient USDC for the 0.01 USDC API fee causes payment failure
