Supports `target_locator` prefix search and cursor pagination. Use this to drive `target_locator` selection for `/monit/tools/catalog` and `/monit/tools/invoke`. ## Restrictions | Aspect | Value | | ----------- | ------------------------------------------------------------------------- | | Rate limits | **600 requests/minute**; **10 requests/second** per account | | Permissions | Any valid `app_key` (read-only; not gated by a specific permission class) | ## Usage * This is a **UI projection view**, not the live source-of-truth used by `/monit/tools/invoke`. A row in the list is no guarantee the target is currently invokable. * `keyword` is a **prefix** match against `target_locator` (ASCII-only, no whitespace, no `|`, max 256 bytes). Substring search is not supported in v1. * `limit` defaults to 50, max 200. Pagination is cursor-based: pass the previous response's `next_cursor` to fetch the next page; an empty / missing `next_cursor` means the last page. * Resetting `keyword`, `limit`, or the tenant context requires resetting `cursor`; never mix a cursor across different filter sets. * `total` is the unfiltered-by-cursor match count for the current `(account_id, keyword)` pair and stays stable across pages. * Fields surface `cluster_name` / `edge_ipport` for diagnostics; treat `updated_at` as "most recently observed" rather than a live online indicator. ## OpenAPI ````yaml /api-reference/monitors.openapi.en.json post /monit/targets openapi: 3.1.0 info: title: Flashduty Open API description: >- Public HTTP API for the Flashduty incident management platform — incidents, notification templates, channels, schedules, monitors, RUM, and platform administration.
