The Google Discovery Service API provides a way to build client libraries, IDE plugins, and other tools that interact with Google APIs. It provides a lightweight, JSON-based API that exposes machine-readable metadata about Google APIs, including: a directory of supported APIs, a machine-readable "Discovery document" for each of the supported APIs that includes, a list of API resource schemas based on JSON Schema and more. All calls to the API are unauthenticated, REST requests that are built on two concepts; The APIs Directory: a list of all APIs that are supported by the APIs Discovery Service, and the discovery document; a machine-readable description of a particular API.
The following is a list of SDKs from our SDK directory that matched your search term. Though your definition of an SDK may differ, in our world, we define SDKs as platform- specific tools for consuming existing APIs of the sort we list in our API directory. For example, the Ruby SDK for consuming the Twitter Ads API. If you think an SDK, API, or other asset is missing from our directory, be sure to check our guidelines for making contributions to ProgrammableWeb.
