This is a website, created out of frustration with uncomplete and outdated Bitcoin Core RPC documentation online.

It was inspired by ChainQuery, which seems to be abandoned. These docs are even simplier, so they can be regenerated by anyone.

Bitcoin version: 0.16.0.

Note that the RPC is from a regtest node (for completeness), so it includes some additional calls that a regular node doesn't have.
