### BU Agent API (Experimental)

A completely new experimental agent built from scratch. Think **Claude Code for the browser**: web scraping, data extraction, file manipulation, and complex multi-step workflows.

*"Here's a CSV with 50 people. For each person, find their LinkedIn profile, extract their current title and company, and return an enriched CSV."* — the BU Agent handles the entire pipeline in a single task.



```python Python
from browser_use_sdk.v3 import AsyncBrowserUse

client = AsyncBrowserUse()
result = await client.run("Find the top 3 trending repos on GitHub today")
print(result.output)
```

```typescript TypeScript
import { BrowserUse } from "browser-use-sdk/v3";

const client = new BrowserUse();
const result = await client.run("Find the top 3 trending repos on GitHub today");
console.log(result.output);
```



### SDK 3.0

New version of the SDK (`3.0.x`) with breaking changes. Please upgrade — the new `client.run()` API is much cleaner. All existing functionality — sessions, profiles, browser control, structured output, streaming, files, skills — is still there.
