# Get log lines for the tasks of an invocation attempt

`GET /v1/vercel-ci/invocations/{invocationId}/attempts/{attempt}/task-logs`

## Request

- Base URL: `https://api.vercel.com`
- URL: `https://api.vercel.com/v1/vercel-ci/invocations/{invocationId}/attempts/{attempt}/task-logs`
- Auth: HTTP bearer

Returns log lines for the tasks of an invocation attempt in a single request, grouped by task. Tasks can be narrowed by name and by conclusion, for example `conclusion=failed` to fetch only the logs of failed tasks. With `search`, every matching task is searched at once and only tasks with matching lines are returned.

## Path parameters

- `invocationId` string, required
- `attempt` string, required

## Query parameters

- `task` string[]: Only return tasks with one of these names (e.g., \"web#test\").
- `conclusion` string[]: Only return completed tasks with one of these conclusions.
- `level` string[]: Only return log lines with one of these levels.
- `search` string: Only return log lines containing this text, ignoring case. Tasks without matching lines are left out, `limit` is ignored, and at most 1000 lines are returned.
- `limit` number: Maximum number of tasks to return (default: 10, max: 25).
- `teamId` string
