• The bridge between API providers and developers

An API is more than an Application Programming Interface, it’s a contract.
We curate and provide technical, financial, legal, social and insiders infos about public APIs,
to restore trust between developers and API providers

Public Ratings

We gradually publish ratings of massively used public APIs, as we get more and more feedback. Leave your email to receive a notification for newly published ratings. Get in touch with us if you would like specific APIs to be rated, or for questions about our methodology.


Understand deeper API providers engagement, value, roadmap and restrictions, and build your apps for the long term

API Providers

Share insider advice, technical info, legal insights and business expectations with developers and 3rd-parties; they will better work with your APIs
