Express API for querying data from your Bitcoin node to build web applications.

Sends HTTP requests to Bitcoin Core node using various RPC commands.

A full tutorial for this API can be found here.

To use the API first make sure to install Node.js (here) and Bitcoin Core here (here).

Clone this repo and add a .env file at the root level of your project. Replace the bitcoinuser and bitcoinpassword values with those in your Bitcoin configuration file (in Bitcoin Core under Settings > Options > Open Configuration File ).

RPC_USER=bitcoinuser
RPC_PASSWORD=bitcoinpassword

If they haven't yet been set, add the following entries to your bitcoin.conf and change both files (restarting bitcoin core) :

rpcuser=bitcoinuser
rpcpassword=bitcoinpassword

Next run

npm install

then

npm run server

to start the server.
