DELETE /trading/markets/{market_id}/orders

Api key auth

Cancels every resting order the authenticated broker has on the market, across all of its accounts. The command is accepted asynchronously: each cancelled order arrives later as a regular order update (status CANCELLED, status_reason USER_REQUEST) whose last_cmd_id_hex equals the returned ref_id. A market that is unknown, closed, settled or voided is rejected with 422. If the market closes while the command is in flight, the engine ignores the command: the close has already cancelled every order.

Headers

PRE-ACCESS-KEY string Required

Broker access key identifier.

Format should match the following pattern: ^[A-Za-z0-9._~-]{1,64}$.
PRE-ACCESS-SIGNATURE string Required

Keyed BLAKE2b-256 signature (hex lowercase, 64 characters).

Format should match the following pattern: ^[0-9a-f]{64}$.
PRE-ACCESS-TIMESTAMP string(date-time) Required

RFC3339 timestamp with milliseconds (e.g., 2025-10-30T06:00:34.075Z). Must be within clock_skew_tolerance (default 5m) of server time.
Idempotency-Key string Required

Stable idempotency token reused on retries. Its server-side context has a sliding TTL of one hour, refreshed by every request carrying the key. Reuse with a different payload returns 409 idempotency_key_mismatch. Reuse with an identical payload returns 202 after the command has been accepted; if its outcome cannot be confirmed after the safe retry period, it returns 503 outcome_unknown and the server makes no further delivery attempts.

Maximum length is 64. Format should match the following pattern: ^[A-Za-z0-9._~-]{1,64}$.
Correlation-Id string

Optional UUIDv7 correlation identifier (lowercase). Must match RFC4122 UUIDv7 (version nibble '7', variant 8|9|a|b). If present but invalid → 422 invalid_correlation_id (error_code).

Format should match the following pattern: ^[0-9a-f]{8}-[0-9a-f]{4}-7[0-9a-f]{3}-[89ab][0-9a-f]{3}-[0-9a-f]{12}$.

Path parameters

market_id string Required

Unique identifier for the market
