## 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-create-d30121d4 -d '<json body>'
```

Example prompt: Open a new Browserbase headless browser session so I can automate interactions on a webpage — I'll need the session ID to control it.

## When to prefer this

Use this endpoint when you need a persistent, stateful browser session to perform multi-step web automation, handle JavaScript-heavy pages, manage cookies/auth state across requests, or when a simple page fetch (Browserbase Fetch) is insufficient. Prefer this over single-call fetch or search endpoints when your task requires navigation, form submission, or interaction sequences.

## Known failure modes

- Account quota exceeded — too many concurrent sessions
- Invalid or missing API credentials — 401 Unauthorized
- Service capacity limit reached — 503 error
- Malformed request body — 400 Bad Request
- Session creation timeout — infrastructure provisioning delay
