Hey @nstrmx thanks for the PR.

Can you take a look at the failing checks. Do you think it's a PR issue, or something else?

[nstrmx]

Fixed it (hopefully).

[JessicaTegner]

Interestingly @nstrmx it seems that the single test failing, is actually because of a 403 rate limit.
What would you say we could do about that? Asking because Idon't know that much about GHs api, when used in this way.

If we add support for the GITHUB_TOKEN as an environment variable to be used in requests, will that solve this?

[JessicaTegner]

yes, that would be acceptable. But I feel like that if that key isn't set, we should fall back to the old behaviour.
Due to the nature of pypandoc, where it's used a lot in CI/CD workflows, I do think that if it's not set, we should fall back to old behaviour so stuff doesn't break

[nstrmx]

Should work now.

[JessicaTegner]

Great work. Lastly, since we now should have 2 download behaviors, we should probably make a test casefor each behavior
