Is Duck.ai something to add?

I am not sure, but Duck.ai seems to be free to use without paying. Maybe something to add?

Duck.ai is not a API provider, we cannot use it the official way. But during the search I find some reverted engine project that makes ducks into API serve, but that's another story, I think u can use the existing handlers to connect to the project.

Free API platforms also exist, check the wiki page I have some recommend providers there.
