Bruck1701/coingecko_client

a Coingecko client gem for Ruby

CoingeckoClient

This is my first gem and the idea was to develop a super simple and lightweight client to connect with Coingecko API. Keep in mind that this is by no means the oficial gem from Coingecko, it is a pet project that I have interest in keeping it working! I published it with the methods that I need for another project, but I'll keep on adding more methods to interact with the rest of the API. Any comments, sugestions, Pull Requests, feel free to contact me.

Installation

Add this line to your application's Gemfile:

gem 'coingecko_client'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install coingecko_client

Usage

The available methods are:

• Check if API is up:

2.7.0 :026 > CoingeckoClient::Client.ping
 => {"gecko_says"=>"(V3) To the Moon!"}

• List coins

List all supported coins id, name and symbol (no pagination required)

2.7.0 :027 > list=CoingeckoClient::Client.coins_list
2.7.0 :028 > list.count
 => 7631
2.7.0 :029 > list.first
 => {"id"=>"01coin", "symbol"=>"zoc", "name"=>"01coin"}

• Supported_vs_currencies
  

Get list of supported_vs_currencies.

2.7.0 :002 > list = CoingeckoClient::Client.supported_vs_currencies
2.7.0 :003 > list.count
 => 55
2.7.0 :004 > list.first
 => "btc"

• Current price
  Get the current price of any cryptocurrencies in any other supported currencies that you need.

CoingeckoClient::Client.price(<coin>,<currency>)

For example:

2.7.0 :016 > CoingeckoClient::Client.price('bitcoin','usd')
 => 9246.4

• Historical market data To get the historical market data(price, market cap and trade volume) of a given coin, you would use:
  _{Coingecko's note about this API call: Minutely data will be used for duration within 1 day, Hourly data will be used for duration between 1 day and 90 days, Daily data will be used for duration above 90 days.}

CoingeckoClient::Client.coin_history(<coin>,<currency>,<number_of_days>)

For example:

CoingeckoClient::Client.coin_history('bitcoin','usd','7')
 => {"prices"=>[[1593511281310, 9161.947854845832], ..., [1594113061000, 9247.986673179646]], market_caps"=>[[1593511281310, 168752424140.90503], ..., [...,...]], , "total_volumes"=>[[...]]}

• Market data from coins:
  Use this to obtain all the coins market data (price, market cap, volume)

2.7.0 :019 > CoingeckoClient::Client.coins_market(currency: 'usd',ids_list:['maker'], price_change_percentage:'7d' )
=> [{"id"=>"maker", "symbol"=>"mkr", "name"=>"Maker", "image"=>"https://assets.coingecko.com/coins/images/1364/large/Mark_Maker.png?1585191826", "current_price"=>465.65, "market_cap"=>419598650, "market_cap_rank"=>30, "total_volume"=>11790566, "high_24h"=>487.76, "low_24h"=>464.65, "price_change_24h"=>-3.61639711, "price_change_percentage_24h"=>-0.77064, "market_cap_change_24h"=>-3408068.16243178, "market_cap_change_percentage_24h"=>-0.80568, "circulating_supply"=>902019.8121058022, "total_supply"=>1005576.0, "ath"=>1798.7, "ath_change_percentage"=>-74.14012, "ath_date"=>"2018-01-20T00:00:00.000Z", "atl"=>168.36, "atl_change_percentage"=>176.28269, "atl_date"=>"2020-03-16T20:52:36.527Z", "roi"=>nil, "last_updated"=>"2020-07-07T09:33:19.687Z", "price_change_percentage_7d_in_currency"=>2.802621306390991}]
