{"API Stack"}

Support This Project

The API Stack

these are the APIs I am tracking on that I have been profiling deeper, which includes the crafting of OpenAPI Specs that describe the surface area of the API. All the definitions are available in the /data folder for this projects Github repository.

All definitions are a work in progress, and I will be working to get them as complete as possible, so that they can be used in documentation, tooling, and other things along the API life cycle in which API definitions are being put to use. I am always working towards a complete as possible of an API definition as makes sense for each company / platform.

If there is a particular API you like to see completed, let me know. If there is an API which you know of a better copy of the OpenAPI Spec is available, let me know as well. You can fork all this work over at the Github repository for the project, and leave any comments on the Github issues for the project. Make sure you head over, and support APIs.guru as well, they are doing the same great work!
