When to use this endpoint

Use this endpoint to abort an abortable run. Confirm the target before calling it.

Identifier Notes

• workerId / worker_id accepts a Worker slug or a path encoded as owner~name from owner/name.

Path Parameters

Parameter	Required	Type	Description
workerId	Yes	string	Worker slug or path. You may paste owner/name; the playground sends it as owner~name for path values.

Request Body

Send the request body with Content-Type: application/json. Required/Optional describes each field; the Try it Request Body badge shows whether the body itself is required.

Field	Required	Type	Description
callback_url	No	string	Callback URL. When provided, CoreClaw sends a POST request after the run status changes or finishes.
is_async	No	boolean	true submits asynchronously without waiting for results; false waits for the run to finish. Defaults to true.
limit	No	integer	Synchronous result window size for runs or reruns. It only controls how many result rows are included in the synchronous response, not the full result set. Constraints: default 20; range 1-100.
offset	No	integer	Zero-based offset for the synchronous result window returned by runs or reruns. Constraints: default 0; minimum 0.

JSON Example

{
  "callback_url": "https://client.example.com/openapi/callback",
  "is_async": true,
  "limit": 20,
  "offset": 0
}

Run Mode

• is_async: true submits the run asynchronously and returns without waiting for execution results. The response includes data.run_slug; then poll the run detail, log, and result endpoints.
• is_async: false waits for the run to finish, equivalent to run-and-wait behavior. Use offset / limit to control the result window returned by the synchronous run.

Request Example

curl -X POST "https://openapi.coreclaw.com/api/v2/workers/YOUR_WORKER_ID/runs/last/abort" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  --data '{"callback_url":"https://client.example.com/openapi/callback","is_async":true,"limit":20,"offset":0}'

Response Example

{
  "code": 0,
  "message": "success",
  "request_id": "req-123"
}

Notes

• API v2 supports Bearer token, the legacy api-key header, and query token. Prefer Bearer token for new integrations.
• This is a Worker-scoped latest-run endpoint; workerId is required and the operation applies only to that Worker’s latest run.
• last means the latest run in the current scope. Use a concrete runId endpoint when the target must be explicit.
• When callback_url is provided, CoreClaw sends callback notifications after status changes or completion. See Callback Notifications.
