# ui_get_build_log_excerpt

The deployments card uses this app-only tool to read its latest build-log lines. App-capable clients expose it to the card. Use `get_deployment_build_logs` for the standalone workflow when your connection exposes it.

This tool appears with the deployments card. Its response includes log entries and `latestAt`. Pass the previous `latestAt` as `since` to fetch newer events. Build logs are separate from runtime logs.

## Parameters

| Parameter | Type    | Required | Description                                                                                                                 |
| --------- | ------- | -------- | --------------------------------------------------------------------------------------------------------------------------- |
| `teamId`  | string  | Yes      | The team ID or slug. Use the team that owns the resource.                                                                   |
| `idOrUrl` | string  | Yes      | The unique identifier or hostname of the deployment.                                                                        |
| `limit`   | integer | No       | How many of the most recent log lines to return. Defaults to 120. Minimum: 1. Maximum: 1000.                                |
| `since`   | number  | No       | Only events after this timestamp (ms), oldest first, so a live view can fetch just what is new. Pass the previous latestAt. |
