Binance

This is an unofficial Ruby wrapper for the Binance exchange REST API.

Installation

Add this line to your application's Gemfile:

gem 'binance'

And then execute:

$ bundle

Or install it yourself as:

$ gem install binance

Features

Current

• Basic implementation of public, account, and withdraw REST API endpoints
• Easy to use authentication
• Methods return parsed JSON
• No need to generate timestamps
• No need to generate signatures

Planned

• Implementation of the User Data Stream API
• Implementation of the Websocket API
• Exception handling with responses
• High level abstraction

Getting Started

Require the gem:

require 'binance'

Create a new instance of the REST Client:

# If you only plan on touching public API endpoints, you can forgo any arguments
client = Binance::Client::REST.new
# Otherwise provide an api_key and secret_key as keyword arguments
client = Binance::Client::REST.new api_key: 'x', secret_key: 'y'

Create various requests:

# Ping the server
client.ping # => {}

# Get kline data
client.klines symbol: 'NEOETH', interval: '1m', limit: 1
# => [[1511682480000, "0.08230000", "0.08230000", "0.08230000", "0.08230000", "0.00000000", 
# 1511682539999, "0.00000000", 0, "0.00000000", "0.00000000", "2885926.46000000"]]

# Create an order
client.create_order symbol: 'XRPETH', side: 'BUY', type: 'LIMIT', 
  timeInForce: 'GTC', quantity: '100.00000000', price: '0.00055000'
# => {"symbol"=>"XRPETH", "orderId"=>918248, "clientOrderId"=>"kmUU0i6cMWzq1NElE6ZTdu", 
# "transactTime"=>1511685028420, "price"=>"0.00055000", "origQty"=>"100.00000000", 
# "executedQty"=>"100.00000000", "status"=>"FILLED", "timeInForce"=>"GTC", "type"=>"LIMIT", 
# "side"=>"BUY"}

# Get deposit address
client.deposit_address asset: 'NEO'
# => {"address"=>"AHXeTWYv8qZQhQ2WNrBza9LHyzdZtFnbaT", "success"=>true, "addressTag"=>"", "asset"=>"NEO"}

Required and optional parameters, as well as enum values, can currently be found on the Binance API Page. Parameters should always be passed to client methods as keyword arguments, with the same capitalization and spelling.
