## 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 x402-browserbase-com-c566d2aa -d '<json body>'
```

Example prompt: Spin up a Browserbase headless browser session so I can automate a web task — give me the WebSocket URL to connect to it.

## When to prefer this

Choose this endpoint when you need a cloud-hosted headless browser session accessible via WebSocket for browser automation, scraping, or web interaction tasks — especially when using the x402 micropayment protocol for per-call billing without subscriptions.

## Known failure modes

- Payment not included or insufficient — session not created, payment error returned
- Invalid request body — 400 bad request
- Service unavailable or capacity exceeded — 503 error
- WebSocket URL expires if session is not connected promptly
- Session time runs out mid-task if paidMinutes are exhausted
