wizagent 0.0.1

Surfing the web in wisdom

WizAgent

WizAgent is a powerful, intelligent web automation and research framework that combines multi-engine web search, deep research capabilities, browser automation, and structured data extraction with advanced LLM support.

Features

• 🔍 Multi-Engine Web Search - Simultaneous search across multiple engines (Tavily, DuckDuckGo, Google AI, SearXNG, Brave, Baidu, WeChat)
• 📚 Deep Research Agent - Autonomous research with iterative query refinement and source aggregation
• 🌐 Browser Automation - Intelligent browser control with natural language instructions powered by cogents-browser-use
• 📊 Structured Data Extraction - Extract structured data from websites using Pydantic models
• 🎯 YAML-Based Schema Parser - Define data models declaratively with the Gem Parser
• 🤖 Multi-LLM Support - Works with OpenAI (compatible), Ollama, and OpenRouter
• 🔄 LangGraph Workflows - Advanced agent orchestration with state management

Quick Start

Installation

pip install -U wizagent

Basic Usage

import asyncio
from wizagent import WizAgent

async def main():
    # Initialize the agent
    agent = WizAgent()
    
    # Web search
    search_result = await agent.search(
        query="artificial intelligence trends 2025",
        max_results_per_engine=5
    )
    print(search_result)
    
    # Deep research
    research_output = await agent.research(
        instruction="What are the latest developments in quantum computing?"
    )
    print(research_output.content)
    
    # Browser automation
    result = await agent.use_browser(
        instruction="Go to Wikipedia and find information about Python programming"
    )
    print(result)

asyncio.run(main())

Core Components

1. Search Agent

Intelligent web search with query polishing, content crawling, and result reranking:

from wizagent import SearchAgent

agent = SearchAgent(
    polish_query=True,           # LLM-powered query optimization
    rerank_results=True,          # Relevance-based reranking
    crawl_content=True,           # Crawl page content
    search_engines=["tavily", "duckduckgo"],
    max_results_per_engine=5
)

result = await agent.run("latest AI developments")
print(result)

2. Deep Research Agent

Multi-loop research with autonomous knowledge gap detection:

from wizagent import DeepResearchAgent

researcher = DeepResearchAgent(
    max_research_loops=3,
    number_of_initial_queries=3,
    search_engines=["tavily", "duckduckgo"]
)

result = await researcher.research(
    user_message="Compare renewable energy adoption in US vs Europe"
)

print(result.content)  # Comprehensive research report
print(f"Sources: {len(result.sources)}")

3. Browser Automation & Data Extraction

Navigate websites and extract structured data:

from pydantic import BaseModel, Field
from typing import List

class StockMetric(BaseModel):
    metric_name: str = Field(description="Metric name")
    value: str = Field(description="Metric value")
    
class StockData(BaseModel):
    stock_name: str
    key_metrics: List[StockMetric]

agent = WizAgent()

# Extract structured data
data = await agent.navigate_and_extract(
    url="https://example.com/stocks",
    instruction="Extract key financial metrics",
    schema=StockData,
    use_vision=True
)

print(data.stock_name)
print(data.key_metrics)

4. Gem Parser - YAML Schema Definition

Define complex Pydantic models using YAML for cleaner configuration:

# snowman_balance.yml
task: StructuredExtraction
metadata:
  name: Stock Financial Metrics
data_models:
  - name: StockMetric
    fields:
    - name: metric_name
      type: str
      desc: Metric name
    - name: value
      type: str
      desc: Metric value
  - name: StockData
    fields:
    - name: stock_name
      type: str
      desc: Stock name
    - name: metrics
      type: List[StockMetric]
      desc: Key metrics
output_model: StockData
instruction: Extract financial metrics from the page

Load and use the schema:

from wizagent.gems import parse_yaml_file

# Parse YAML to Pydantic models
result = parse_yaml_file("snowman_balance.yml")
StockData = result.target_model

# Use with WizAgent
agent = WizAgent()
data = await agent.navigate_and_extract(
    url="https://example.com",
    instruction=result.instruction,
    schema=StockData
)

Advanced Examples

See the examples/ directory for more use cases:

• examples/agent/search_agent_demo.py - Web search with crawling and reranking
• examples/agent/deep_research_demo.py - Autonomous research workflow

Architecture

WizAgent is built on top of:

• cogents-core - Core LLM abstractions and agent framework
• cogents-browser-use - Browser automation with intelligent control
• wizsearch - Multi-engine web search orchestration
• LangGraph - Workflow orchestration and state management
• Pydantic - Data validation and structured outputs

Configuration

Set environment variables for LLM configuration. The configuration is provider-specific:

OpenAI-compatible

export COGENTS_LLM_PROVIDER=openai
export OPENAI_API_KEY=your-api-key
export OPENAI_CHAT_MODEL=gpt-4  # optional, default: gpt-3.5-turbo
