WikidataAPIWrapper#

class langchain_community.utilities.wikidata.WikidataAPIWrapper[source]#

Bases: BaseModel

Wrapper around the Wikidata API.

To use, you should have the wikibase-rest-api-client and ``mediawikiapi `` python packages installed. This wrapper will use the Wikibase APIs to conduct searches and fetch item content. By default, it will return the item content 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.
