Daily API RoundUp: Lufthansa, ARToolKit, LimeSpot, CoolClimate

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.

Six new APIs have been added to the ProgrammableWeb directory today in Climate, Auto, and Recommendations categories, among others. Here’s a summary of what is new.


The CoolClimate API is an offering from the UC Berkeley API Management Portal. The API allows developers to create projects that calculate carbon footprints, a measurement that assists with the management of climate impact. The API is available as a limited preview, and users can access a set of parameters from an Excel document.

This API is categorized under Climate. See ProgrammableWeb’s complete list of Climate APIs.

ARToolKit provides developers with a software Library for creating augmented reality (AR) applications. The open source library offers opportunities to overlay virtual imagery onto the real world. It offers an API to help developers integrate camera, image, video, and detector features into an application. We’ve primarily categorized the API under the Augmented Reality category. See ProgrammableWeb’s complete list of Augmented Reality APIs.

Deutsche Lufthansa AG is a large international airline based in Germany. Use the Lufthansa Open API to build air travel apps. The API offers access to several data sets including: country, city, and airport codes; flight schedules and status; nearest airports and lists of aircrafts. We’ve categorized the this API under the Air Travel category. See ProgrammableWeb’s complete list of Air Travel APIs.

RegNet offers automotive solutions for simplifying vehicle regulations’ processes. The company is based in Japan and focuses on automation, collection of data, database design, product localization, and English/Japanese translation. The RegNet API can be requested with JSON or XML formats and displays responses as JSON, XML, CSV, Python, Ruby, or PHP. The RegNet API is listed under the Auto category. See ProgrammableWeb’s complete list of Auto APIs.

LimeSpot personalization engine delivers customized content based on user behavior and demographics. The LimeSpot Personalizer API generates behavior-based recommendations such as: top picks, related, trending, recent views, or popular picks. Add user demographics, interests, or data about your application’s content to increase the engine’s results. We’ve listed the LimeSpot Personalizer API under the Recommendations category. See ProgrammableWeb’s complete list of Recommendations APIs.

KeyCAPTCHA provides website authorization via solving simple puzzles. For example, a user would place the missing jigsaw puzzle piece of an apple into the image of the apple. The Common CAPTCHA API is useful to developers who prefer to integrate visuals instead of Captcha words. Common CAPTCHA API works with a private API Key and JavaScript code.

This API is listed under the Captcha category. See ProgrammableWeb’s complete list of Captcha APIs.


Use CloudBoost to add data-storage, search, graphs, and realtime to your apps. The CloudBoost API provides database services for building apps. CloudBoost provides this SDK for JavaScript developers interested in working with the CloudBoost API.
