Daily API RoundUp: MAAS, Addison Lee, Waitlist, Friendbuy, Celitech

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 Transportation, Museums, and Location. Highlights include an API that provides estimates about C02 emissions and an API for adding users to a waiting list. Here's a rundown of the latest additions.


Museum of Applied Arts and Sciences (MAAS) is Australia's contemporary museum for excellence and innovation in applied arts and sciences. The database contains thousands of images and documents from the museum's science and collections that are stored in the Powerhouse Museum, Sydney Observatory and Museums Discovery Centre.

Celitech is a cellular data Platform. The Celitech Bee APITrack this API enables developers to add cellular data eSIM to their offerings. The eSIM API provides wireless data services that can be shared digitally (e.g. using activation or QR codes) and programmed by size, start/finish dates, speed, and location to support a wide variety of use cases. This API is listed in the Wireless category.

Carbon Interface APITrack this API provides estimates about C02 emissions from activities. Users provide details about the activity and the API uses the most accurate estimation methodologies to compute the amount of C02 emitted from doing the activity. Emissions data can be returned for electricity, airplane flights, product manufacturing, shipping, and other specific activities. The Carbon Interface API is listed in the Climate category.

Waitlist APITrack this API enables developers to add users and their email addresses onto a waiting list. It will provide a user with information about where they are in line ("You're 3 in a line of 10"). The service includes a "jump ahead in line" feature for users that provide referrals, and stats for viewing Waitlist attendees. Add Waitlist to your website or application with 5 lines of code. The API is listed in the Engagement category.
