Cancel all (kill switch)

DELETE/v1/px/orders/allcancel scope

Market Maker APIE6 decimal strings throughoutA | B

Cancel all of your open orders across all markets.

Send X-PX-Key: pxk_…. This endpoint requires the cancel scope — an insufficient scope returns 403, not 401, and this line does not use Bearer sessions. To request a key and see the limits, visit the onboarding page.

Behaviour

No parameters; the body may be empty.
Completes in one call; no need to list markets first.
Same response shape as batch cancel.
