Google Knowledge Graph Search API Use the API to do the following: Perform entity resolution on an organization, a product, a location, a book, a movie, and many more entities. Link your private entity to a globally unique Cloud Knowledge Graph machine ID (MID).

The basic structure of the query is to find, or match, entities and return those entities, where the entities you want to find are identified in parentheses. For example, the query MATCH (e) RETURN e returns entities of any type. The number of entities returned is only limited by the knowledge graph's configuration.

The Knowledge Graph API Search API allows developers a quota of up to 100,000 (one hundred thousand) read calls per day per project at no charge.

Microsoft Graph includes APIs that are available at no additional cost with user subscription licenses and APIs and services that are metered. Metered APIs and services in Microsoft Graph incur costs based on usage.
