Notes for Aptos API

1. When communicating with a Aptos RPC node, the Aptos client implements a JSON-RPC specification, a communication protocol allowing one to make remote calls and execute them as if they were made locally.
2. The Aptos API allows developers to communicate with the Aptos blockchain to build applications. The best way to use the Aptos API is to use a Web3 library such as web3.js if using JavaScript or web3.py using Python.
