DocuAPI is a multilingual API documentation theme for Hugo created and maintained by Bjørn Erik Pedersen, the lead maintainer and co-creator of Hugo itself. It’s built on top of the Slate API docs generator, which itself was inspired by Stripe’s and PayPal’s API docs. The JavaScript section of DocuAPI has been rewritten from Jquery to AlpineJS.​​​​​​. - Source: dev.to / about 2 years ago

I've used Slate to document APIs which similarly will produce a local website. You can host that privately or there's built in support to push to github pages if you're hosting it in a github repo. The documentation itself is all written in markdown and managed separate from your API code. Source: about 2 years ago
