I've downloaded it and it started syncing; however, I don't have a single idea on how to use it. I wanted to have a local Bitcoin blockchain explorer, and BTC RPC Explorer(https://github.com/janoside/btc-rpc-explorer/) lacked address indexing, which I need (to be able to find all input and output transactions of any X address). Does Fulcrum has something similiar? I am not sure where to browse the JSON API, the documentation doesn't mention the URL used.

Also I want to use it on Bitcoin BTC, while the documentation mentions Bitcoin Cash, which confuses me further (https://electrum-cash-protocol.readthedocs.io/en/latest/index.html).

Any ideas? Haven't been able to figure it out yet.
