Error Handling

from praisonai_tools import WikipediaTool

if "error" in result:
    if result["error"] == "Disambiguation":

        print(f"Error: {result['error']}")
else:

How It Works

​
Best Practices

Wikipedia works without credentials — ideal for quick factual lookups.
When a title matches multiple pages, pick from the returned options instead of guessing.
Fetch summaries rather than full articles so the agent works with fewer tokens.
