New York Times has its own set of "controlled meta-data," which it uses to categorize its stories. The TimesTags API provides access to this meta-data. Use the API to kickstart your own classification system, or to look up tags that can then be used to find stories using the newspaper's Article Search 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.
