This is a website, created out of frustration with uncomplete and outdated Bitcoin Core RPC documentation online.
</p>
<p>
It was inspired by <a href="http://chainquery.com/bitcoin-api">ChainQuery</a>, which seems to be abandoned. These docs are even simplier, so they can be regenerated by anyone.
</p>
<p>
Made by <a href="https://twitter.com/karel_3d">@karel_3d</a>; license of the docs is MIT (see <a href="https://github.com/bitcoin/bitcoin/">bitcoin repo</a>), license of the scripts and webpage is also MIT ((C) 2018 Karel Bilek) (<a href="https://github.com/bitcoin-rpc/bitcoin-rpc.github.io">github repo</a>)
</p>
<p>
Bitcoin version: 0.16.0.
</p>
<p>
Note that the RPC is from a regtest node (for completeness), so it includes some additional calls that a regular node doesn't have.
