Google APIs Discovery Service

Discovery Document

The Discovery Document describes the surface for a particular version of an API. The information provided by the discovery document includes API-level properties such as an API description, resource schemas, authentication scopes, and methods.

Methods

The Discovery document focuses on the RESTful method of invoking an API. The discovery.apis.get method retrieves the REST-based Discovery document for a particular API.

getRest
Retrieve the description of a particular version of an API.
list
Retrieve the list of APIs supported at this endpoint.
