Use this to poll actions that returned 202; HTTP 200 can contain any action status. Stored observations contain metadata with empty tree and refs, not the full snapshot; submit a fresh observe action to obtain current refs. ## OpenAPI ````yaml /openapi/source/external/agent-browser/agent-browser.json get /browser_sessions/{id}/actions/{actionId} openapi: 3.1.0 info: version: 1.0.0 title: Telnyx API x-latency-category: interactive x-endpoint-cost: light description: >- Isolated, short-lived browser sessions for AI agents — navigate, observe, click, fill, and screenshot through one API. ## Authentication All endpoints require a Telnyx API key sent as a Bearer token in the `Authorization` header. ## Session Quota Creating a session is subject to a concurrent-session quota per organization. When capacity is exhausted, create returns `429 quota_exceeded` with `retryable: true`. Close unneeded active sessions or wait for capacity before retrying. ## Error Responses Request errors use `{ "error": { "code": string, "message": string, "retryable": boolean } }`. Execution failures are reported on action resources with HTTP 200 and `data.status` set to `failed` or `unknown`. A request can also return HTTP 503 `execution_lost`; inspect action and session state before retrying because the action may already have taken effect. contact: email: support@telnyx.com servers: - url: https://api.telnyx.com/v2 description: Telnyx API v2 security: - bearerAuth: [] tags: - name: Browser Sessions description: Create, list, get, and close browser sessions. - name: Actions description: >- Execute browser actions: navigate, observe, click, fill, select, press, scroll, wait_for, screenshot, batch. - name: Artifacts description: Download screenshots and other artifacts. paths: /browser_sessions/{id}/actions/{actionId}: get: tags: - Actions summary: Get action result description: >- Returns the stored status and result of an action.

Action failures (policy_denied, stale_observation, stale_ref, navigation_blocked, timeout, execution_lost, result_too_large) are returned on the action resource with HTTP 200. An unknown action with execution_lost has retryable=false; inspect session state and reconcile possible effects before any new action. Separately, a request may return HTTP 503 with a top-level execution_lost error and retryable=true; that is not proof of safe re-execution. required: - code - retryable created_at: type: string format: date-time started_at: type: - string - 'null' format: date-time completed_at: type: - string - 'null' format: date-time required: - id - session_id - seq - type - status - result - request - error - created_at - started_at - completed_at GatewayError: type: object required: - errors properties: errors: type: array items: type: object required: - code - title properties: code: type: string title: type: string detail: type: string source: type: object properties: pointer: type: string meta: type: object properties: url: type: string format: uri ErrorResponse: type: object properties: error: type: object properties: code: type: string message: type: string retryable: type: boolean required: - code - message - retryable required: - error responses: Unauthorized: description: Unauthorized — missing or invalid API key. content: application/json: schema: $ref: '#/components/schemas/GatewayError' example: errors: - code: '10009' title: Authentication failed detail: Could not find any usable credentials in the request. source: pointer: / meta: url: https://developers.telnyx.com/docs/overview/errors/10009 NotFound: description: Session or artifact not found. content: application/json: schema: $ref: '#/components/schemas/ErrorResponse' example: error: code: not_found message: session not found retryable: false securitySchemes: bearerAuth: type: http scheme: bearer ````
