Daily API RoundUp: UnFound, PSMA, KryptoCal, userstack

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.

Twelve APIs have been added to the ProgrammableWeb directory in categories including Mapping, Weather, and Addresses. Highlights include an API for free surface-based weather observations. Here's a rundown of the latest additions.


UnFound is an intelligent news insights application. Three APIs are provided for news analysis, which we have added to our Natural Language Processing category. UnFound Adaptive Text Summarization API enables users to summarize a piece of text, an article, or a webpage (by URL) by extracting the most important sentences that best capture the meaning of the entire text. UnFound Relevant Wikipedia Pages API can extract important topics from any given text or URL and suggests all relevant Wikipedia Pages related to those topics. UnFound Keyword Extraction API uses advanced Natural Language Processing (NLP) techniques to extract the most important keywords and phrases from the document or URL provided. Instead of extracting single worded keywords, it can identify phrases as well as multi-worded keywords from the input text.

PSMA provides location and geospatial information about Australia from Australia's government data sources. The PSMA Addresses API is a Restful Resource that aims to answer questions about addresses in Australia. This includes services for addresses reverse geocoding, address validation, geocoding, filtering and more. It is an address verification service that offers a range of attributes for a selected address, commonwealth and state electorate, etc., and is filed under the Addresses category. See ProgrammableWeb's complete list of Addresses APIs.

KryptoCal provides cryptocurrency daily related events and the latest announcements for each coin, including ICOs. The Kryptocal Event API provides programmatic access to all of Kryptocal events and announcements. API methods are available to retrieve lists of categories, lists of active events based on a from and to date, retrieve past events for a specific coin and more. It lists all the upcoming events for all different coins to use in production, free of charge, with call limits at every 5 minutes. The API is listed under the Cryptocurrency category. See ProgrammableWeb's complete list of Cryptocurrency APIs.

userstack enables users to detect any browser, device & OS in real-time. The userstack REST API accurately detects browser, device and operating system information by parsing user agent strings, allowing developers to optimize application performance for individual users. API results are provided within milliseconds in either JSON or XML format. This API is listed under the Parsing category. See ProgrammableWeb's complete list of Parsing APIs.

Tapleader is an application installment analytics tool. The Tapleader API allows developers to monitor the performance of app install sources and determine the performance of each marketing channel from a unified interface. The API can only be integrated into apps using an Android SDK, and is listed under the Analytics category. See ProgrammableWeb's complete list of Analytics APIs.

Metropolitan Atlanta Rapid Transit Authority (MARTA) is the public transport system of Atlanta, GA. The MARTA Bus Realtime RESTful API provides bus schedule data from the MARTA system. The MARTA Rail Realtime RESTful API returns a Feed with train arrivals in real time in the Atlanta area. Both APIs have been listed in our Transportation category. See ProgrammableWeb's complete list of Transportation APIs.

Convictional provides software for B2B wholesalers. The Convictional Commerce API returns JSON data to make transactions online. Methods include actions, orders, products, partners, prices, logs, and changes. The API is listed under the eCommerce category. See ProgrammableWeb's complete list of eCommerce APIs.

Bing Maps Elevations API allows users to get elevation values for a set of locations, a polyline path or area on the Earth. It provides a set of elevations and the associated zoom level is returned in the responses that request elevation values that supports JSON or XML format for the response. Developers can locate the elevation of users with this API, which is listed in the Mapping category.

Synoptic Data is a Public Benefit Corporation (PBC) that provides low (or no) cost earth data to support research, education, and exploratory usage. The Synoptic Data Mesonet API provides weather data from 75,000 public and private observing stations including units with positions, air temperature, elevation, and volts; elevation with sensor variables, longitude, latitude, time zone, and observations; and summary with data query time, metadata, data parsing time, number of objects, and functions. The API is listed under the Weather category. See ProgrammableWeb's complete list of Weather APIs.
