Overview

Wikidata provides authoritative structured entity descriptions for people, places, organizations, scientific concepts, and other knowledge-graph items through the public Wikidata Action API. It is useful when the query needs compact entity definitions, disambiguation, or canonical identifiers rather than long-form narrative content.

Known Quirks

• Results expose short entity descriptions, not long-form article content.
• language=en is hardcoded in v1.
• type=item intentionally filters out lexemes and properties.

Quality Bar

• Evidence items have non-empty title and url.
• No crash on empty or malformed API response.
• Source channel field matches the channel name.
