Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 agbrowser-30-minute-browser-session-b8ad1923 -d '<json body>'
```

Example prompt: Spin up a 30-minute browser session starting at https://example.com using a 1280x800 viewport, English locale, and honest identity mode so I can navigate and read the page content.

## When to prefer this

Choose this endpoint when your AI agent needs to interact with a real, JavaScript-rendered browser environment — especially for sites that block plain HTTP scrapers, require cookie/session handling, or need multi-step click navigation. Prefer it over static HTTP fetching when the target page is dynamic. The 30-minute window suits medium-complexity automation tasks; use shorter session variants for quick reads and longer sessions for deep multi-page workflows. Stablecoin payment via x402 makes it suitable for fully autonomous agent pipelines without OAuth setup.

## Known failure modes

- Payment failure or insufficient USDC balance via x402 returns 402 Payment Required
- Invalid start_url format returns 400 Bad Request
- Viewport dimensions outside allowed range (w: 320-3840, h: 200-2160) return 400 validation error
- Session quota or capacity limits exceeded return 503 Service Unavailable
- Target URL unreachable from browser sandbox returns session error after launch
- Session expires after 30 minutes, subsequent commands return session-expired error
