About this API
Entity Search takes a query string ("Bill Gates", "Mount Everest", "Apple") and returns the entity Bing identifies: entity type (Person/Place/Organization), description text, representative image, related URLs, Wikipedia/official links. Its core value is entity linking — the same name ("Apple") can refer to multiple entities; Entity Search returns the most likely candidate with context, plus a _type field for programmatic handling. Typical use cases: knowledge cards in a SERP, NLP-pipeline disambiguation, or as an intermediate layer for knowledge-based QA. Sunsets 2025-08-11 with the Bing Search family.

FAQ
Does it work for Chinese entities?+
Yes, but Chinese coverage is weaker than English — China-specific entities (e.g. local companies) may not be indexed.
