This is an OpenAPI spec for the Lemmy API. It is used to generate the API docs, and can also used to generate client libraries. I am not affiliated with Lemmy, and it is not guaranteed that this spec is up to date.
You will need typeconv to generate the API spec. You can install it with npm install -g typeconv.
To generate the API spec, update the lemmy-js-client submodule and run node generate.js. This will generate the spec in openapi.json.
I have not fully tested the generated spec, so there may be some issues. If you find any, please open an issue or PR.
