The counter price must be at least 1,000 sats above the offer, a multiple of 1,000, and at least 5,000 sats (422 counter_price_invalid carries minimum_counter_sats), and cannot outlive the offer.

Counterparty atomic units. A string preserves integers beyond JSON’s safe numeric range; divisibility affects display, never this wire value.

Integer satoshis, exactly representable as a JSON number. Aggregated historical volume can exceed Bitcoin’s supply, so this is the safe JSON integer ceiling, not a single-transaction spending limit.
Deadline for reviewing this template. The listing itself has no Bitcoin-level expiry.

On 422 mempool_rejected from a broadcast: which deterministic node policy refused the bytes. Retrying the same bytes fails the same way. fee_floor: re-quote at a higher fee_rate. chain_too_long: too many unconfirmed ancestors; wait for a confirmation, then retry. truc: a version-3 (TRUC) package rule, such as spending an unconfirmed version-3 output; wait for a confirmation, then retry.
The node’s own reject reason, on mempool_rejected (422) and on state_changed (409) when a broadcast lost to a conflicting or replacing spend.
Present and true when mempool_policy is chain_too_long or truc.
On a checkout or accept completion refused as mempool_rejected: the journaled settlement ended and every listing, bid, and asset claim it held was released (its inputs were proven unspent). The quote or accept is replaced; request a new one.
Batch listing routes only: every refused item. The first sets the status and code.
One refused item in a batch refusal’s refused_listings array. Nothing in the batch was changed.

On 429 rate_limited: the exact seconds until the oldest counted request leaves the window; a retry then is admitted (also sent as Retry-After). Limited writes are bucketed per route scope in exact sliding 60-second windows: by session address when a valid x-session-token is present, otherwise by IP, with a per-IP ceiling across sessions. Expensive writes: 20, ceiling 120. Signed completions: 120, ceiling 600. Session minting (/auth/*): 60 per IP. A request refused by any bucket is counted by none.
