## 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 runx-marketplace-ausca-remote-browser-session-7b25118b -d '<json body>'
```

Example prompt: Spin up a remote browser session with CDP access through Ausca so I can automate a checkout flow on a website — I need a fresh 10-minute session, invoking it now.

## When to prefer this

Choose this endpoint when you need a short-lived, fully managed remote browser with CDP access for tasks like web scraping JavaScript-heavy pages, browser-based automation, visual testing, or any workflow requiring real browser rendering — without provisioning your own infrastructure. Prefer this over local headless browser setups when you need a cloud-hosted, disposable session billed per use at low cost ($0.05).

## Known failure modes

- Payment failure or insufficient USDC balance — session not created
- Session capacity exceeded on provider side — no browser available
- Idempotency key collision — duplicate session request rejected
- Session timeout before task completes — 10-minute limit enforced strictly
- Invalid or missing runner field — request rejected with schema validation error
- Network connectivity issues preventing CDP connection to remote browser

## How this service works

## Output
