Why is the API giving me a 403 Forbidden? (lemmy.ml)

I'm toying about with writing a client in Rust.

Example code online uses the API endpoint https://lemmy.ml/api/v3/post/list, and when I go to this link in a browser, it doe indeed load data. However, when I try to load it from a program, it gives me a 403 Forbidden. Does anyone know why this could be?

This one got me too.

lemmy.ml specifically is running requests through a user agent checker - and if it's empty, which reqwest is by default, you will get a 403.

You can see an example here of using ClientBuilder to set a user agent string: https://github.com/CMahaff/lasim/blob/main/src/lemmy/api.rs

So set any string (should be your project name) and then it should work.
