The Open Source Initiative API is used to build applications that are "license aware" which means that any business can determine if the license is open source or not. This API stores a list of common identifiers of services which allows a user to take a Software Package Data Exchange (SPDX) ID, and know if it is approved by calling the Open Source Initiative API. This API returns specific information about a license such as if it is obsolete, popular or OSI Approved.
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.
