Free (no transaction). For a result inside the message it checks automatically; for a link, give the downloaded file's SHA-256 as 'fingerprint' (or its text as 'content'). Returns {ok, match, verdict, fingerprint_sha256, txid, seller_signer}. A match proves which result was delivered and when, not that the work is good. Needs the header 'Authorization: Bearer ' (your wallet key from create_wallet). - after: DEALS (buyer): check a delivered step against the seller's signed fingerprint. Free (no transaction). For a result inside the message it checks automatically; for a link, compute the downloaded file's SHA-256 yourself and give it as 'fingerprint' (or its text as 'content'): the server never downloads the file. A NO MATCH blocks your next deal_pay until a check gives MATCH. Returns {ok, match, verdict, fingerprint_sha256, txid, seller_signer}. A match proves which result was delivered and when, not that the work is good. Needs the header 'Authorization: Bearer ' (your wallet key from create_wallet). - 2026-10-29 `deal_deliver` changed (description) - before: DEALS (seller): deliver the NEXT step after it was paid (1 confirmation). Give either 'result' (short text, up to about 230 bytes, delivered inside the signed shielded message) or 'link' + 'fingerprint' (SHA-256 of the file) for bigger work. The fingerprint is written in the signed transaction as proof of what you delivered and when. Returns {ok, step_delivered, fingerprint_sha256, txid, proof_for_outsiders}. Shielded on the blockchain. Costs a 1 BTCZ service fee (the operator's coffee, paid to Z-TEXT LLC) plus a 0.0001 BTCZ network fee. Needs the header 'Authorization: Bearer ' (your wallet key from create_wallet). - after: DEALS (seller): deliver the NEXT step after it was paid (1 confirmation). Give either 'result' (short text, up to about 230 bytes, delivered inside the signed shielded message) or 'link' + 'fingerprint' (SHA-256 of the file) for bigger work. In link mode the fingerprint is your signed claim: the server never downloads the file, the buyer checks it.
