Search and retrieve Wikipedia articles

Overview

Wikipedia tool allows you to search Wikipedia and retrieve article content. No API key required.

The user asks a factual question; the agent searches Wikipedia and returns a summary.

Installation

pip install "praisonai[tools]"

No API key required!

Quick Start

1. Simple Usage

   from praisonai_tools import WikipediaTool
   
   # Initialize
   wiki = WikipediaTool()
   
   # Search
   results = wiki.search("Python programming")
   print(results)
   
2. With Configuration

   Use the same tool with an agent — see Usage with Agent below, or pass env vars and options from the sections above.

Usage with Agent

from praisonaiagents import Agent
from praisonai_tools import WikipediaTool

agent = Agent(
    name="Researcher",
    instructions="You are a research assistant. Use Wikipedia to find information.",
    tools=[WikipediaTool()]
)

response = agent.chat("Tell me about quantum computing")
print(response)

Available Methods

search(query, max_results=5)

Search Wikipedia for articles.

from praisonai_tools import WikipediaTool

wiki = WikipediaTool()
results = wiki.search("machine learning", max_results=5)

# Returns:
# [{"title": "Machine learning"}, {"title": "Deep learning"}, ...]

get_page(title)

Get full Wikipedia page content.

page = wiki.get_page("Python (programming language)")

# Returns:
# {
#     "title": "Python (programming language)",
#     "url": "https://en.wikipedia.org/wiki/...",
#     "summary": "...",
#     "content": "...",
#     "categories": [...]
# }

summary(title, sentences=5)

Get a brief summary of an article.

summary = wiki.summary("Artificial intelligence", sentences=3)

# Returns:
# {"title": "Artificial intelligence", "summary": "..."}

Configuration Options

wiki = WikipediaTool(
    language="en"  # Wikipedia language (en, es, fr, de, etc.)
)

# For Spanish Wikipedia
wiki_es = WikipediaTool(language="es")

Function-Based Usage

from praisonai_tools import wikipedia_search

# Quick search without instantiating class
results = wikipedia_search("neural networks", max_results=3)

CLI Usage

# Use with praisonai (no API key needed)
praisonai --tools WikipediaTool "What is quantum computing according to Wikipedia?"

Error Handling

from praisonai_tools import WikipediaTool

wiki = WikipediaTool()
result = wiki.get_page("Some Ambiguous Term")

if "error" in result:
    if result["error"] == "Disambiguation":
        print(f"Multiple options: {result['options']}")
    else:
        print(f"Error: {result['error']}")
else:
    print(f"Title: {result['title']}")

Common Errors

Error	Cause	Solution
wikipedia not installed	Missing dependency	Run pip install wikipedia
Disambiguation	Multiple pages match	Use one of the returned options
Page not found	Article doesn’t exist	Check spelling or search first

Supported Languages

Use ISO language codes:

• en - English
• es - Spanish
• fr - French
• de - German
• zh - Chinese
• ja - Japanese
• And many more…

How It Works

Best Practices

No API key needed

Wikipedia works without credentials — ideal for quick factual lookups.

Handle disambiguation

When a title matches multiple pages, pick from the returned options instead of guessing.

Summarise, don't dump

Fetch summaries rather than full articles so the agent works with fewer tokens.
