Overview

Entity knowledge card API for entity resolution and entity enrich: send a name (person, place, organization, or concept) and get back a structured knowledge graph profile plus a readable summary in one call. Built for agents that need to disambiguate a name or build a knowledge card without stitching a Wikidata lookup to a Wikipedia fetch by hand. Composite: one call runs wikidata-resolve + wikipedia-search + wikipedia-lookup + company-enrich in parallel. wikidata-resolve is required and returns the QID, type claims, and key claims; wikipedia-search and wikipedia-lookup add a readable summary and disambiguation candidates; company-enrich is a best-effort org profile probe, only meaningful when the entity is a company, and degrades silently otherwise. Use it as an entity knowledge card API, entity resolution tool, or knowledge graph lookup.
