GitHub Pages: how to enforce custom Content-Type type for any file?

Question

We are currently using GitHub Pages as a simple API mock server. We put all mock files under docs/ and simply GET username.github.io/project/api/someAPI to retrieve data. However, by default, the Content-Type returned by GitHub Pages is application/octet-stream instead of application/json for files with no extensions, therefore our frontend code throws errors when parsing the result.

I want to know is there any way to change the returned Content-Type for files with no extension on GitHub Pages?

Same issue here, but with a MPEG-4 video coming back with either no content type (IE, Edge) or a text content type (Chrome). Video plays in Chrome, not in IE or Edge. — ACPrice

https://docs.github.com/en/pages/getting-started-with-github-pages/about-github-pages#mime-types-on-github-pages suggests this is impossible:

you can't specify custom MIME types on a per-file or per-repository basis

From experimentation, you can create subdir/index.json which will cause https://owner.github.io/repo/subdir/ to successfully (200) serve content with type application/json. But https://owner.github.io/repo/subdir will serve a 301 redirect, which an API client may not tolerate.

Taking a hint from https://jekyllrb.com/docs/configuration/options/ I tried creating _config.yml

include: .htaccess

and .htaccess

ForceType application/json

without success. I also found https://github.com/jekyll/jekyll/issues/5454 suggesting this is not possible.
