}Cancel all open orders
Cancels every open order of the authenticated wallet across all markets, sides and outcomes. Takes no filters: a request carrying marketId, side or outcome (in the body or the query string) is refused with 400 cancel_all_takes_no_scope and nothing is attempted. Works from a snapshot of the orders open when the request arrives, so an order placed while the cancel runs may not be included — stop quoting before you call it. One call may stop before it has attempted the whole snapshot: every id it did not reach comes back in notCancelled as not_attempted, so repeat the call until none does. Response: { cancelled: string[], notCancelled: { orderId: reason }, remainingQty: { orderId: qty } }; read cancelled.length for the count. 409 shard_owned_elsewhere means nothing was attempted — repeat the call. 503 cancel_all_unknown means the outcome was lost and some orders may already be cancelled: stop placing orders, read your open orders, and do not re-issue cancel-all automatically (a new call is a new sweep over a fresh snapshot). Rate limited at 1 req/sec per wallet — intended for operational wind-down, not per-order cleanup. No KYC / deposit-tier gate, but the call is refused for paused, banned or geo-restricted wallets; use POST /api/orders/cancel-batch to unwind in those states.

}Authorizations
Partner / integrator key — format ps_live_<keyId>_<secret>. Partner keys are issued by PredictStreet; a user can also create keys bound to their own wallet from their account settings in the web app. Never ship to a browser. multi_wallet partners must additionally send X-User-Wallet: 0x<40-hex> on every authenticated request to declare the acting wallet. See the API keys guide for scope taxonomy, partner kinds, rate limits, and rotation procedure.
Headers
Required for multi_wallet partners on every authenticated request; ignored for single_wallet. Declares the acting end-user wallet for this request — drives KYC checks, balances/positions/orders attribution, rate-limit buckets, and audit. Lower-cased server-side. Missing on a multi_wallet key → 401 api_key_user_wallet_required; malformed → 401 api_key_user_wallet_invalid. The on-chain CTFExchange/Vault contracts still verify EIP-712 signer ↔ vault binding, so loosening API-layer attribution is safe by construction.

Response
Sweep answered. Ids that were not cancelled are listed in notCancelled with a reason; repeat the call while any is not_attempted.
Ids (from the snapshot taken when the request arrived) whose cancellation was accepted. Acceptance and effect are separate moments: a read of the order taken right after this response can still show the pre-cancel status — poll the order rather than assuming. This is the array of cancelled order ids. Use cancelled.length for the count.
Map of orderId → reason for every snapshot order that was not cancelled. Same reason vocabulary as POST /api/orders/cancel-batch; not_attempted means this call stopped before reaching the id — repeat the call to cover it.

Map of orderId → quantity still unfilled when that order was cancelled (decimal string), for exactly the ids in cancelled. An upper bound, not a traded quantity: size a replacement quote from it, and book fills from the order read.
