Daily API RoundUp: Userly, GraphQL 360, Pickpoint, Coinpaprika

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, 3D, and Location. Featured today is an API that detemines if email addresses are disposable, and an API for creating panoramic 3D grapics. Here's a rundown of the latest additions.


SunsetWx provides sunset and sunrise predictions using an algorithm comprised of meteorological factors. The SunsetWx Sunburst Web API allows users to Fetch SunsetWx's sunrise and sunset quality predictions. Sunburst currently supports JSON format, with geographical data conforming to GeoJSON. This API is listed under the Predictions category. See ProgrammableWeb's complete list of Predictions APIs.

 e-Khalti is a mobile digital wallet for an instant, secure and hassle-free online payments. The e-Khalti Payments API allows developers to integrate online payments into their websites and mobile applications. The e-Khalti API is listed under the Payments category.

Northwestern University provides a Course Data API for developers to create applications. The API returns data about courses with endpoints for schools, terms, subjects, instructors, buildings, rooms and more. The API is listed under the Education category. See ProgrammableWeb's complete list of Education APIs.

Userly provides website SEO and analytics services. The Userly SEO & Analytics API can be used to build customized dashboards to show Userly Analytics data, automate reporting assignments, and integrate Userly Analytics information. Userly analyzes Alexa data, similarWeb data, Whois data, social media data, Moz check, Search Engine Index, Google page rank, IP analysis, malware check and more. The Userly API is listed under the SEO category. See ProgrammableWeb's complete list of SEO APIs.

Pickpoint is a geocoding IoT service for developers. The PickPoint API allows developers to perform geocoding, reverse geocoding, and address lookups. Geocoding converts geographic addresses to latitude/longitude coordinates, reverse geocoding converts latitude/longitude coordinates to geographic addresses. The address lookup Function converts OSM identifiers to geographical addresses with corresponding coordinates. The API is listed under the Location category. See ProgrammableWeb's complete list of Location APIs.

Coinpaprika provides a cryptocurrency research Platform for accessing data such as market overview, prices, charts, teams, events, coin details and more. The Coinpaprika API returns current cryptocurrency market data for coin prices, volumes, market caps, ATHs, return rates and more. This API is listed under the Cryptocurrency category. See ProgrammableWeb's complete list of Cryptocurrency APIs.

Validation API is an API to validate and verify email addresses in real-time. Developers can use Validation API to automatically detect disposable (temporary) email addresses and check if a mailbox exists. It is listed in our Email category. See ProgrammableWeb's complete list of Email APIs.

GraphQL 360 is a 360 degree tour service. The GraphQL 350 API allows developers to create and consume 360 degree panoramic tours. It is integratable with tools such as A-Frame, React360, and Unity. 360 degree tours are essentially a graph which makes GraphQL a good choice for implementation. Both the API and the underlying panoramas are delivered by Amazon Web Services. We've listed this API in our 3D category.
