Library for retrieving ticker data from popular crypto-currency-related Exchanges

cryptick

A Clojure library designed to retrieve ticker data from several popular crypto-currency exchanges:

• btc-e
• bter
• okcoin
• bitstamp
• havelock

Cryptick is intended to retrieve ticker data, fast, from various exchanges. No authentication or API credentials are required.

http-kit is used for fast asynchronous requests. Standard (ticker ...) returns a promise. Use @(ticker ...) to block for the result.

When the response is received, additional processing of the JSON is performed. This will ensure that all numeric fields are returned as numbers, rather than strings.

Usage

In Project

[cryptick "0.1.0"]

(:require [cryptick.core :refer [ticker])
@(ticker :btce "btc_eur") ; (ticker exchange pair)

Valid exchanges:

• :btce
• :bter
• :okcoin
• :bitstamp
• :havelock

Valid currency pairs:

Please check with each site as to valid currency pairs.

In the havelock's case, use the market symbol for the pair argument.

Since bitstamp only does btc_usd, the pair is hardcoded, but you still need to specify it.
