Includes SDK V2 and CLI requests, input constraints, response fields, and Deepline credit cost. List changes for a monitor. Tool ID: `contextdev_list_monitor_changes` ## Run this action Use the TypeScript SDK for a single call. Put `ctx.tools.execute(...)` inside a Play when the call should be durable, scheduled, or run across a CSV. ```ts theme={null} import { Deepline } from 'deepline'; const deepline = await Deepline.connect(); const result = await deepline.tools.execute( 'contextdev_list_monitor_changes', { "monitor_id": "monitor_123" }, ); console.log(result.toolResponse.raw); ``` ### CLI ```bash theme={null} deepline tools execute contextdev_list_monitor_changes --input '{ "monitor_id": "monitor_123" }' --json ``` ## Example response The SDK exposes this shape at `result.toolResponse.raw`. Values below are representative. ```json theme={null} { "data": { "data": [ { "mode": "web", "id": "id_123", "monitor_id": "monitor_123", "target_type": "page", "change_detection_type": "exact", "title": "VP of Engineering", "summary": "example", "detected_at": "2026-01-15T12:00:00Z", "url": "https://example.com/resource" } ], "has_more": true, "next_cursor": "cursor_123" } } ``` Use `deepline tools get contextdev_list_monitor_changes --json` for the latest machine-readable contract. ## Input reference List the changes detected by one monitor, with optional time and tag filters. | Name | Type | Required | Default | Details | | -------------------- | --------- | -------- | ------- | --------------------------------------------------------------------------------------------- | | `payload.monitor_id` | `string` | Yes | — | — | | `payload.tag` | `string` | No | — | Filter to items that have this tag. | | `payload.since` | `string` | No | — | Only include items at or after this ISO 8601 timestamp. Format: `date-time`. | | `payload.until` | `string` | No | — | Only include items before this ISO 8601 timestamp. Format: `date-time`. | | `payload.limit` | `integer` | No | — | Maximum number of items to return per page (1-100). Defaults to 25. Minimum: 1. Maximum: 100. | | `payload.cursor` | `string` | No | — | Opaque pagination cursor from a previous response. |

## Deepline cost * Pricing model: `fixed` (per call). * Estimated Deepline credits: `0` per pricing unit. * Provider-native pricing may still exist outside Deepline credit billing. ## Related documentation * [Context.dev provider guide](/docs/providers/contextdev/guide) * [SDK V2 quickstart](/docs/sdk-v2/quickstart) * [SDK reference](/docs/sdk-v2/sdk-reference) * [Run tools across a CSV](/docs/sdk-v2/batch-csv)
