I'd suggest List[Dict] to be enough in this case since. We can safely assume the returned JSON will always be a list of objects, the rest is on the caller. > > How are type hints enforced? Do we need to turn that on somehow? They're not. Python will always remain a dynamically typed language. The whole point of type hinting is for static analysis via 'mypy' and for various IDEs that can actually make use of those as well during completion which is nice. (I'm wondering whether the jedi vim plugin is capable of reading those too) Erik
