Close an acquihire

Last updated Jun 14, 2026

Query Parameters

dry_runbooleanOptional

If true, simulate the mutation and return the would-be resource, any cascaded resources, and a fee estimate — without side effects. Available on every mutation.

Default false

Test-mode only. real mirrors live timelines with mocked state responses. fast uses a ~1-second cadence per filing (default in dev). instant makes mutations synchronous — the response carries the terminal resource — for CI tests and demo flows that need the post-submit state visible immediately.

Live-mode rejection. Sending this header with a sk_live_… / rk_live_… / sk_dashboard_live_… bearer returns 400 invalid_header_for_live_mode. Live filings move at the speed of the underlying state-of-incorporation portal; there is no client-side simulation knob.

One of"real""fast""instant"

Default "fast"
