# Proxy RPC call to the underlying node

`POST /cryptos/{cryptoCode}/node/rpc`

Allows you to make RPC calls to the underlying cryptocurrency node (e.g., Bitcoin Core) via NBXplorer. This endpoint acts as a proxy, forwarding your RPC requests to the node and returning the node's responses.

By default, only a handful of RPC methods are authorized. You can use [configuration](https://github.com/btcpayserver/NBXplorer/blob/master/docs/API.md#configuration) `--btcexposerpc` or `NBXPLORER_BTCEXPOSERPC=1` to allow all methods.

Go to [The JSON-RPC specification page](https://www.jsonrpc.org/specification) and the [Bitcoin Core RPC page](https://developer.bitcoin.org/reference/rpc) for more information.
