## 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 notte-browser-session-start-e4169a8d -d '<json body>'
```

Example prompt: Start a new headless Chromium browser session with proxy rotation and CAPTCHA auto-solving enabled, a 1280x800 viewport, and a max duration of 30 minutes.

## When to prefer this

Choose this endpoint when you need a fully managed, remotely controlled cloud browser session with built-in proxy rotation and CAPTCHA solving — especially for anti-bot websites. Prefer it over self-hosted Playwright/Puppeteer when you want zero infrastructure management and pay-per-session pricing.

## Known failure modes

- Invalid browser_type value (not chromium, chrome, or firefox) returns a 400 error
- Exceeding account session limits returns a quota or rate-limit error
- Network or infrastructure failure may prevent session creation, returning a 500 error
- Invalid viewport dimensions may cause session misconfiguration
- Payment failure via x402 protocol blocks session creation

## How this service works

Start a new browser session. Configure browser type, proxies, viewport, and session timeout.

## Output

Returns a session object including a session ID, connection endpoint, and status indicating the browser session is ready for commands such as navigation, interaction, and scraping.
