}Cancel a run
Durably requests cancellation of a run. The response remains cancelling until the owning worker acknowledges the signal or its execution lease expires. Repeating the request is idempotent. Closing a client connection does not cancel a run, and cancellation does not roll back external effects that already completed. Only the API key that started the run may cancel it.

}Authorizations
Workspace API key created in Erstan Settings. Keys carry scopes (agents:list, agents:read, agents:write, agents:run, runs:read, tasks:execute, documents:read, documents:write, files:read, files:write). Agent access follows the key creator's current workspace, team, and agent permissions. Agent draft creation requires agents:write; update, validation, and publishing require both agents:read and agents:write; draft testing also requires agents:run. Keys with tasks:execute must include at least one allowed project or team (allowedProjectIds / allowedTeamIds); keys with document or file scopes must include at least one allowed team. Empty allowlists mean no access — the API fails closed.
Path Parameters
Run ID returned by POST /v1/public/agents/{agentId}/runs.
Response
Cancellation state, including idempotency and acknowledgement timestamps.
