Every day, the ProgrammableWeb team is busy, updating its three primary directories for APIs, clients (language-specific libraries or SDKs for consuming or providing APIs), and source code samples. If you have new APIs, clients, or source code examples to add to ProgrammableWeb's directories, we offer forms (APIs, Clients, Source Code) for submitting them to our API research team. If there's a listing in one of our directories that you'd like to claim as the owner, please contact us at editor@programmableweb.com.
Ten APIs have been added to the ProgrammableWeb directory in categories including Cryptocurrency, Payments, and Project Management. Highlights include a low latency, high performance email service from SparkPost to its European customers, and AWS X-Ray SDKS. Here's a rundown of the latest additions.
