# Interaction tools

Interact with your Bitcoin nodes using JSON-RPC API.

Use curl or Postman to invoke Bitcoin API methods.

Example below demonstrates how to get basic network information:

curl https://user-name:pass-word-pass-word-pass-word@nd-123-456-789.p2pify.com -d '{"method":"getblockchaininfo","params":[],"id":1}'

# Development tools

# Python

Work with Bitcoin from your Python application.

Install bitcoincli.
Configure the client to use host and port of the node RPC endpoint, the corresponding RPC username, and password:

from bitcoincli import Bitcoin

host = "nd-123-456-789.p2pify.com"
port = "80"
username = "user-name"
password = "pass-word-pass-word-pass-word"

bitcoin = Bitcoin(username, password, host, port)

Invoke any methods from the Bitcoin API specification:

info = bitcoin.getblockchaininfo()
print(info)

The example code above should output basic network information:
