Wikipedia API

As explained in Grokking AI Applications

A public interface for searching Wikipedia articles and retrieving their summaries, source URLs, and full text programmatically.

The Wikipedia API lets an application search articles and retrieve structured results: an article title, summary, source URL, and full text. A Langflow component exposes this capability for agent workflows. section 5.4

A typical retrieval workflow has three practical controls:

• Enter a search query, such as Rome. section 5.4
• Choose how many matching articles to retrieve; one article supports a focused lookup. section 5.4
• Inspect the returned title, summary, source URL, and full text, then optionally limit the retrieved character count. section 5.4

Searching for Rome

Run the Wikipedia component with Rome as the query and one result requested. The output provides a compact table containing the matching article's title, summary, source URL, and full text. section 5.4

How Grokking AI Applications covers it

How deep it goes

Explains query, result-count, output, and character-limit controls, but does not descend into API request implementation.

Examples

Uses a Rome search returning one article with its title, summary, source URL, and full text.

What you can do after

Operate/configure a Wikipedia component, inspect article results, and expose it as an agent tool.

How it connects

Connects Wikipedia retrieval with AI agents, tools, web search, and URL-based page fetching.
