Most of the ones I know of are paid course / consultants. The UK govt has on demand seminars.

Accessibility: Learn the best practises to build all-inclusive websites.
Here are a free resources:
In the digital content space, here are some interesting tools:
# 1
Accesibe
This is a company that provides accessibility consultation, suggesting ways to make the file/presentation/website accessible.
They also have an extremely interesting widget that allows for customisation as per PwD profile (See white human figure icon on blue; bottom right of the page). Tools like these could. be built by the government.
# 2
Venngage
Accessible Colour Palette generator. If one looks at tny text to background colour contrast ratio, - anything above 4.5.1 is a WCAG 'A' & ~ 10.0.0 is a AAA. Of course for the site to be AAA, navigation, screen reader compatibility,.. matter too.
# 3
accessibleweb
Colour contrast checker
Anything that simplifies adoption, should be made modularised, like the API you spoke about. Either a company / the government provides it for others to use thereby lowering costs of bringing in accessibility.
