Installation

Installation is simple, as it should be:

pip install bitex-kraken

Qickstart

After installing, requesting data is easy:

>>>from bitex import BitexSession
>>>session = BitexSession()
# bitex.BitexSession provides a set of methods to execute the most common queries
>>>r = session.ticker("kraken", "XBTUSD")
# The response objects returned are bitex.BitexResponses, which behave like regular requests.Response objects.
>>>r
<KrakenResponse [200]>
>>>r.json()
{
    "error":[],
    "result": {
        "XXBTZUSD":{
            "a":["3809.10000","1","1.000"],
            "b":["3809.00000","1","1.000"],

Development

If you’re looking to work on or with bitex-framework, you’ll want the development environment setup. We’ve supplied a few make targets to make your life easier:

# Install bitex and its development requirements
make development

We also supply targets to run code formatters, linters and tests:

# Run code formatters
make pretty

# Verify code style
make style-check

# Run tests via tox
tox -e testenv

If you’d like to contribute to the project, please have a look at CONTRIBUTING.rst on some general pointers about how development takes place, what the expected steps of you are and what requirements we have to merge a PR.
