Is there any way (plugin / project / etc.) to provide a REST API for all tables in WordPress, including those tables that are created by additional plugins?

I had the idea to use a headless CMS like directus or strapi, but there is none that is schema-agnostic, so none will understand WordPress relations. I’m also not aware of any plugin that covers all tables or allows me to configure the REST API by my own.

I would end up implementing my own REST API, I know how to do that, but I would prefer to avoid that.

Is there any shortcut for me in that matter?
