## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability browserbase-status-6fbd5ee2
```

Example prompt: Check whether my Browserbase browser session abc123 is still active and running.

## When to prefer this

Use this endpoint when you need to poll or verify the lifecycle state of a specific Browserbase session before issuing further commands, after a long operation, or to confirm a session has not timed out. Prefer this over creating a new session when you already have a session ID and need to confirm its availability.

## Known failure modes

- Session ID not found returns 404 error
- Invalid session ID format returns 400 error
- Expired or already terminated session may return a terminal status or 404
- Authentication failure returns 401 or 403 if credentials are invalid
