class langchain_community.utilities.wikipedia.WikipediaAPIWrapper[source]#

Bases: BaseModel

Wrapper around WikipediaAPI.

To use, you should have the wikipedia python package installed. This wrapper will use the Wikipedia API to conduct searches and fetch page summaries. By default, it will return the page summaries of the top-k results. It limits the Document content by doc_content_chars_max.

Create a new model by parsing and validating input data from keyword arguments.

Raises [ValidationError][pydantic_core.ValidationError] if the input data cannot be validated to form a valid model.

self is explicitly positional-only to allow self as a field name.
