HTTP API

The HTTP API serves as the mode of communication between nodes and dApps. It can be used to query important information from the blockchain.

HTTP API can be used while testing smart contract logic to find out the blockchain status and other relevant information.

It encapsulates three interfaces that are a part of the HTTP API, and can be regarded as being API in themselves:

1. Restful

2. RPC

3. Websocket

The ports that the above APIs use are as follows:

API	Port
Restful	20334
Websocket	20335
RPC	20336

The following sections describe each of the APIs and the respective methods in detail.
