The PGP key is E2C73BC53B9118A0. I can't find it on any keyserver, yet.

That key isn't the one linked to the Protonmail account either. [0] (You'll get a payload of all linked public keys with that link).

This is a nice way to verify Protonmail addresses. Is this API publicly documented?

That particular part is detailed on the knowledge base [0], so... Yes? For just this bit.

But I don't think the full API is documented. There are some attempts to reverse engineer an API from the WebClient [1], but they tend to be... Brittle.
