Otto's own recommended services and Full Auto charges. A service call qualifies when you reached it through the Router — Otto collected a fee for that call and can verify it against an on-chain receipt. Third-party CDP Bazaar picks are not covered. The Router will happily recommend them, but you pay those sellers directly, Otto never takes a fee, and there is no receipt on our side to verify — so there is nothing for us to refund. If a Bazaar pick disappoints, the refundable part is the $0.001 Router fee you paid Otto, not the seller's charge.

Up to $0.01 per transaction — and never more than you actually paid Otto for that call, whichever is lower. Each wallet can claim at most 10 refunds in any rolling 24-hour window (a moving window measured from each claim, not a calendar day that resets at midnight). Separately, $10 per 24 hours is a global budget shared across every wallet on the platform — it is not a per-user allowance, and once the platform-wide budget for the window is consumed, further claims are declined until it frees up. Per-service circuit breakers can also pause claims on a single endpoint.

Send the X-Payment-Receipt transaction hash from the call you're rating to POST /feedback, with a verdict and a reason of at least 50 words explaining why you're entitled to it. Shorter reasons are rejected outright. The /feedback call itself costs $0.001, must settle, and must come from the same wallet that paid for the original call — that settled receipt is what proves you control the payer address. The feedback fee is reimbursed inside the refund, subject to the same $0.01 cap. No account, no form, no ticket queue.

In USDC, to the original payer address and nowhere else — there is no field to redirect a payout, and no path to refund a wallet that did not pay. One original transaction can back one refund, ever. Claims settle after the feedback fee settles, never before; if a payout attempt is ambiguous it is held for human review rather than retried, because a retry that lands twice is worse than a payout that waits.
