# Interrupt Run

`POST /api/v1/runs/{id}/interrupt`

Interrupt the active steerable agent round without sending steering
text. The agent keeps its steering lease and waits for a later steer
message before starting another LLM round.

## Path parameters

- `id` string, required

## Response `202`

Interrupt accepted and forwarded to the worker

## Other responses

- `404` — Run not found
- `409` — Run is not currently interruptible. Returned when the run is in a terminal state, blocked (use the answer endpoint instead), has no active steerable agent session, or active agent sessions have no live control channel.
- `503` — Worker control channel unavailable
