tip

If you installed lfx directly with uv pip install lfx, install this provider from the long-tail metapackage:

uv pip install "lfx-bundles[<bundle>]"

Replace <bundle> with this page's provider name, for example qdrant. To install every long-tail provider at once, run uv pip install "lfx[bundles]". See the Bundle list for the exact extra name.

If you installed Langflow with uv pip install langflow, these bundle components are already included.

Bundles contain custom components that support specific third-party integrations with Langflow.

This page describes the components that are available in the Wikipedia bundle.

tip

Wikipedia components are useful tools for agents that need reliable sources for information retrieval, such as tutoring chatbots or generic research assistants.

Rather than broad internet searches or recall from internal model data, these components provide specific data returned from Wikipedia API requests.

Wikidata API

This component performs a similarity search using the Wikidata API.

It accepts a string text query, and it outputs a Table containing the search results.

Wikipedia API

This component searches and retrieves information from Wikipedia with the WikiMedia API search endpoints, and then outputs the response as a Table.

Wikipedia API parameters

Some parameters are hidden by default in the visual editor. You can modify all component parameters through the component inspection panel that appears when you select a component.

Name	Type	Description
input_value	String	Input parameter. The search query input.
lang	String	Input parameter. The language code for Wikipedia. Default: en.
k	Integer	Input parameter. The number of results to return.
load_all_available_meta	Boolean	Input parameter. Whether to load all available metadata.
doc_content_chars_max	Integer	Input parameter. The maximum number of characters for document content.
