Telnyx Agent Browser is now available on api.telnyx.com. It gives an AI agent its own isolated browser session through an API, limited to the sites you allow, so the agent can use websites that have no API.

`POST /v2/browser_sessions` starts a short-lived Chromium session. A session lives 15 minutes by default (up to 30) and closes after 5 idle minutes by default, so nothing carries over between tasks.`policy.allowed_domains` when you create a session, with 1 to 50 patterns. `example.com` matches only that host, and `*.example.com` matches its subdomains but not the apex, so list both to cover a site and its subdomains. A navigation outside the list fails with `policy_denied`.` observe` action returns the rendered page as a text tree with element references. An agent clicks, fills and selects by reference instead of pixel coordinates.`navigate`, `click`, `fill`, `select`, `press`, `scroll`, `wait_for`, `screenshot` and `batch`. A batch runs 1 to 50 actions in order in a single request.` provisioning` right away. Poll `GET /v2/browser_sessions/{id}` until the status is `ready`, then send actions.` idempotency_key` on session creation or on an action so a retried request returns the original result instead of repeating it.`stale_observation`, so an agent can tell a blocked site from an out-of-date element reference.

```
POST /v2/browser_sessions
{
  "policy": { "allowed_domains": ["example.com"] }
}
```

`/v2/browser_sessions/{id}/actions`. Use the `observation_id` and a `ref` from the observation to `DELETE /v2/browser_sessions/{id}`.
