Launches a cloud browser agent that executes a natural-language task by navigating websites, filling forms, clicking buttons, and extracting structured data like a human

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 browser-use-cloud-ai-browser-automation-23a664a5 -d '<json body>'
```

Example prompt: Go to the TechCrunch homepage, find the three most recent AI-related articles, and pull back each article's title, author, publication date, and URL as structured data.

## When to prefer this

Choose this endpoint when you need a cloud-based AI agent to complete browser tasks expressed in plain English, especially multi-step workflows involving form filling, clicking, and data extraction across real websites — with built-in CAPTCHA solving, residential proxies, and no need to manage browser infrastructure yourself. Prefer this over headless browser SDKs or scraping APIs when the task is complex, requires human-like interaction, or involves dynamic JavaScript-rendered content.

## Known failure modes

- CAPTCHA not solved — agent may time out or fail on sites with aggressive bot detection
- Task ambiguity — vague natural language instructions may cause the agent to misinterpret the goal
- Site structure changes — dynamic or JavaScript-heavy pages may cause navigation failures
- Authentication required — agent cannot log in without credentials provided in task
- Rate limiting or IP blocking by target site despite residential proxies
- Insufficient balance — call fails if account balance is below $1 USDC
- Session timeout — long-running multi-step tasks may exceed session limits

## How this service works

Browser Use: AI browser automation agents in the cloud. POST a natural-language task and an agent navigates websites, fills forms, clicks buttons, extracts structured data, and completes multi-step workflows just like a human. Stealth-enabled remote browsers with CAPTCHA solving, residential proxies, live session view, and optional structured output. Payments top up your balance; managing your session is free — you only pay to open a new browser. Docs: https://docs.browser-use.com

## Output

Returns a session result object containing the completed task output (as structured or free-text data depending on configuration), the session ID, a live session view URL for monitoring, task completion status, and any extracted structured data matching a requested schema.
