VENDOR NEUTRAL APIs

Mo Alkady, Hart

17,000+ APIs available today

Developers today face incomplete API documentation, random documentation and even lacking

Building a vendor-neutral, portable and open specification for providing technical metadata for REST

APIs.

Imagine being able to understand any API by

just reading the documentation.

Seeing custom APIs as competitive edge

Lack of investment in open source

Seeing APIs as a secondary need to their software

We can’t make everyone happy

APIs are getting more and more complex
