Is there a CMS with static page generation and RESTful API support?

Question

CMS

Tell me if there is any CMS that supports generating tables with data, managing objects, requesting them from the server via RESTful API or via WebSocket.
You need to generate some kind of entities and simply administer them. You need a simple tool.
Then this html will run on machines where there is no PHP or nodejs and so on. You need static output.
