Daily API RoundUp: Postmen API, Appstax, Marvel Comics, Clever SDKs

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.

Three APIs and several SDKs have been added to the ProgrammableWeb directory in categories such as Recognition, Content and Shipping. Here's a summary of the new additions and how they can assist developers.

APIs IBM Watson AlchemyVision API analyzes images by using NLP tech and Machine Learning algorithms to determine their content and context. Users can submit images as either URLs or files. The API will recognize, tag, and categorize the images as well as detect faces, identify people, and return confidence scores.

We've categorized this API under the Recognition category. See ProgrammableWeb's complete list of Recognition APIs.

IBM Watson AlchemyData News API enables users to query the world's news sources and blogs as they would a database. The API indexes 300K news and blog articles every day with natural language processing. This allows for highly targeted searches and trend analyses. Allows search on articles from the last 60 days. This API is listed under the Content category. See ProgrammableWeb's complete list of Content APIs.

Postmen consolidates all shipping APIs into one single API. The Postmen API offers a free shipping system to integrate with existing apps. It features rates, labels, and manifests APIs for both domestic and international shipping. The Postmen API is REST based, responds in the JSON format, and supports all shipping carriers. The Postmen API is listed under the Shipping category. See ProgrammableWeb's complete list of Shipping APIs.


The Marvel Comics API provides developer access to metadata describing Marvel's 70+ years of comics. The RESTful API delivers JSON formatted information about creators, characters, series, storylines, individual issues, and crossover events. The Marvel Comics PHP SDK by developer Chad Gray allows developers to integrate the Marvel Comics API into their PHP applications. This Library requires PHP 5.4+.

Appstax lets developers define their own data model. The Appstax API provides a backend that incorporates services such as hosting and signup code. The SDK provided by Appstax Technologies call the Appstax API to integrate with existing applications. They are: Appstax Java SDK , iOS SDK, Android SDK and JavaScript SDK.

Clever provides data processing, organizing, Integration, and security for student information. Administrators and teachers can upload student information to Clever once and share that information with other enabled systems and apps. The Clever Data API exposes Clever's information retrieval functionality. Clever provides a Ruby SDK, JavaScript SDK, Go SDK, PHP SDK and a Python SDK for integration.

Urban Airship's Push helps developers increase engagement with customers, and create recurring revenue streams. With the API, developers can deliver sports scores, breaking news, or user-generated content like game challenges directly to users' pockets, in real time. The Urban Airship Ruby SDK by Urban Airship allows to interact with the marketing features of the API, aiming to offer mobile engagement to users. Installation can be complete with gem. Usage demonstrates code to broadcast to all services and create a tag push.
