As of version 0.10.0, Bitcoin Core provides
an unauthenticated HTTP REST interface. The interface runs on the
same port as the JSON-RPC interface, by default port 8332 for mainnet and
port 18332 for testnet. It must be enabled by either starting Bitcoin
Core with the -rest option or by specifying rest=1 in the
configuration file. Make sure that the RPC interface is also activated.
Set server=1 in bitcoin.conf or supply the -server argument when
starting Bitcoin Core. Starting Bitcoin Core with bitcoind automatically
enables the RPC interface.
The interface is not intended for public access and is only accessible from localhost by default.
{{WARNING}} A web browser can access a HTTP REST interface running on localhost, possibly allowing third parties to use cross-site scripting attacks to download your transaction and block data, reducing your privacy. If you have privacy concerns, you should not run a browser on the same computer as a REST-enabled Bicoin Core node.
The interface uses standard HTTP status codes and returns a plain-text description of errors for debugging.
