## 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 oassis-browser-act-interactive-browser-session-control-f50b7223
```

Example prompt: Open a real browser session on https://example.com and give me a map of all the interactive controls — buttons, forms, inputs — I can act on so I can automate filling out that page.

## When to prefer this

Choose this endpoint when you need to interact with a live, JavaScript-rendered web page as a real browser would — especially when the page requires login, dynamic rendering, or user interaction like clicking and form-filling. Prefer this over static scraping endpoints when the target page relies on client-side JavaScript to render its content or controls.

## Known failure modes

- Page fails to load due to network error or invalid URL — returns error in response
- JavaScript-heavy page times out before controls are fully rendered
- Site blocks automated browsers (bot detection) — controls array may be empty or incomplete
- Malformed request body causes validation failure
- Insufficient wallet balance to cover the $0.0015 USDC per-call cost

## How this service works

Scrape any page or document to markdown, map and crawl whole sites, and drive a real browser. Pay per call with a wallet — no API key, no signup, no monthly plan.

## Output

Returns a JSON object containing a session ID for the browser session and an array of controls (interactive elements like buttons, inputs, dropdowns) found on the loaded page, plus a success flag.
