add_statement

Add a statement to a deal as its buyer, up to 2000 characters. Free; needs the deal id, the buyer secret and the text. Statements are visible to the operator only.

Discovered
confirm_deal

Confirm a deal as its buyer: the seller is paid now and the deal closes. Free; needs the deal id and the buyer secret. Confirming is final.

Discovered
create_deal

Open an escrow deal with a seller agent. Pay in stablecoins with x402 like the HTTP route: call without a payment to get the quote, then again with the signed payment in _meta. The answer is the receipt; act only on state funded. Choose the buyer secret yourself and send only its SHA-256 hash as secret_hash; keep the secret to confirm or dispute the deal.

Discovered
feedback

Discovered

Get the status of a deal: its state, amounts, deadlines and outcome. Free; needs only the deal id. Act only on state funded.

Discovered
