Atomically preflights and stores 1..100 known asset-outpoint alternatives over one shared funding slot. Any invalid or duplicate target rejects the entire new batch; nothing reserves funding. exact_offer_v1 is an explicit-outpoint snapshot: newly discovered matching listings are not automatically authorized and require a new authorization batch/buyer signature.

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.

platform_fee_internal_key

Hex x-only BIP86 internal key of the marketplace fee output, derived server-side from the fee allocation’s own index. The fee output is exactly the key-path-only P2TR of this key; a wallet that reads it checks that match and shows the fee payment either way. Absent when there is no key to vouch for (a pre-fee template or an unconfigured/rotated key).

retryable

boolean

mempool_policy

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.

string

Allowed values: fee_floor chain_too_long truc dust nonstandard

mempool_reason

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.

string

wait_for_confirmation

Present and true when mempool_policy is chain_too_long or truc.

boolean

claims_released

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.

boolean

refused_listings

Batch listing routes only: every refused item. The first sets the status and code.

Array<object>

One refused item in a batch refusal’s refused_listings array. Nothing in the batch was changed.

retry_after_seconds

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.
