This lightweight API is used within Google and made available to other developers. It makes all of Google's APIs listable and provides additional information about each API, including a full list of resources or methods.
Google uses the API Discovery API internally to maintain client libraries for all of its APIs, as well as to fill a sandbox with potential API calls.
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.
