{"page":"buyer guarantees","paid_only_on_delivery":"settlement runs after delivery, in one fused step: the goods are fetched first, and the payment settles only when the origin delivered. If the seller's side (or ours) fails, nothing is submitted on-chain and the buyer was never charged.","the_exception":"a request the BUYER got wrong is billed even when the answer disappoints: if the origin did the work and answered (record not found, bad parameters), that answer is the product. You pay for the answer, not for the answer being yes.","receipts":{"permanent":"every settled payment has a public receipt at /r/{payment_id}; the unguessable id is the capability, keep the URL","lost_receipt":"recoverable from the transaction hash: GET /r/by-tx/{tx_hash} redirects to the receipt. Your exchange withdrawal history names the wallet; the explorer names the tx.","downloads":"the receipt page offers the goods again while the delivery allowance lasts, and a self-contained receipt file at /r/{payment_id}/download"},"report_a_problem":{"how":"POST /v1/checkouts/{checkout_id}/reports with a category, optionally your receipt id and a sentence. No account needed.","what_happens":"the report lands on the seller's record and our operators see it; the response tells you what happens next"},"honesty":"settlement is non-custodial: money moves from the buyer's wallet to the seller's, on-chain, and checkout402 never holds it. We cannot claw money back. What we CAN do is refuse to settle a failed delivery in the first place, which is why the guarantee is built into the order of operations instead of into a refund policy."}
