Add FastAPI web interface with full browser-use integration

[Copilot]

Implements a production-ready web frontend to enable browser automation through a web interface, addressing the requirement to "implante o frontand e integre corretamente todas as funçoes".

Backend (browser_use/web/api.py)

• FastAPI server with 5 REST endpoints + WebSocket for real-time task updates
• Full integration with Agent, BrowserSession, and all LLM providers (OpenAI, Anthropic, Google)
• Pydantic request/response models with validation
• Auto-generated API docs at /docs and /redoc

Frontend (browser_use/web/static/index.html)

• Single-page interface for task submission with provider/model selection
• Real-time status updates and result display
• Configurable agent settings (headless, vision, max_steps)

Usage

# Start server
python examples/ui/web_interface.py

# Or programmatically
from browser_use.web.api import app
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000)

# REST API
curl -X POST http://localhost:8000/api/task \
  -H "Content-Type: application/json" \
  -d '{"task": "Find AI news", "llm_provider": "openai", "model": "gpt-4o-mini"}'

# WebSocket for streaming updates
ws://localhost:8000/ws/task

Documentation

• docs/web-interface.md: Complete API reference, deployment guide, examples
• browser_use/web/README.md: Quick start and module overview
• API docs auto-generated at /docs (Swagger UI) and /redoc

Testing

Added comprehensive test suite covering all endpoints with FastAPI TestClient.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• esm.ubuntu.com
  • Triggering command: /usr/lib/apt/methods/https (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
