Zaif API library

zaif

REST API Client for Zaif Exchange

Zaif Exchange用のREST APIクライアント

Features

• A single client to call any type of API (public, trading, futures, leveraged). 任意の種類のAPI（公開、取引、先物、レバレッジド）を呼び出す単一のクライアント。

• Convenient methods for making API calls using keyword arguments - packs JSON for you! キーワード引数を使用してAPIコールを作成するための便利なメソッド - JSONをパック！

• Near 100% test coverage. 100％近いテストカバレッジ。

• Tab-completable methods and attributes when using IPython. IPython を使用した場合のタブで完成可能なメソッドと属性。

Installation (インストール)

zaif is available on PYPI. Install with pip:

$ pip install zaif

or with easy_install:

$ easy_install zaif

The library is currently tested against Python versions 2.7 and 3.4+.

API Reference (APIリファレンス)

The official documentation can be found on the Zaif API reference page. 公式のドキュメントは Zaif APIのリファレンスページ にあります。

Prerequisites (前提条件)

The first thing you need to do is to Sign Up with Zaif.

Next, you need to obtain an API Key and an API Secret. If you’re writing code for your own Zaif account, you can create API keys on Zaif API Settings page. You can create multiple API keys with different permissions for your applications.

NOTE: Make sure to enable appropriate permissions for the API key.

Getting started (始める)

Create a Client object for interacting with the API: APIと対話するための Client オブジェクトを作成します：

from zaif.client import Client

api_key = 'your api key'
api_secret = 'your api secret'

client = Client(api_key,api_secret)

Error handling (エラー処理)

All errors occurring during interaction with the API will be raised as exceptions. These exceptions will be subclasses of zaif.errors.ZaifError.

• When the error involves the API server, the error raised will be a subclass of zaif.errors.APIServerError. エラーがAPIサーバに関係する場合、発生したエラーは zaif.errors.APIServerError のサブクラスになります。

• When the error is associated with the response received form the API server, zaif.errors.APIResponseError will be raised. エラーがAPIサーバーから受信したレスポンスに関連付けられている場合、zaif.errors.APIResponseError が発生します。

For full details of error responses, please refer to the relevant API documentation.

Error	HTTP Status code
NotFoundError	404
InternalServerError	500
ServiceUnavailableError	503
GatewayTimeoutError	504

Usage (使い方)

I’ve done my best to make the code clean, commented, and understandable; however it may not be exhaustive. For more details, please refer to the Zaif API official documentation.

• Use args for URI paths

Testing / Contributing (テスト/寄稿)

Any contribution is welcome! The process is simple:

• Fork this repo

• Make your changes

• Run the tests (for multiple versions: preferred)

• Submit a pull request.

Testing for your current python version (現在のPythonバージョン)

Tests are run via nosetest. To run the tests, clone the repository and then:

# Install the required dependencies
$ pip install -r requirements.txt
$ pip install -r test-requirements.txt

# Run the tests
$ make tests

If you’d also like to generate an HTML coverage report (useful for figuring out which lines of code are actually being tested), make sure the requirements are installed and then run:

$ make coverage

Testing for multiple python versions (複数のPythonバージョン)

I am using tox to run the test suite against multiple versions of Python. Tox requires the appropriate Python interpreters to run the tests in different environments. I would recommend using pyenv for this.

However, the process is a little unintuitive because tox does not seem to work with multiple versions of python (installed via pyenv) when inside a pyenv virtual environment. So, first deactivate your pyenv virtual environment:

$ (zaifapi-venv) pyenv deactivate

and then install tox with pip or easy_install:

$ pip install tox # or
$ easy_install tox

Install python versions which you want to test:

$ pyenv install 2.7.14
$ pyenv install 3.5.0
$ pyenv install 3.6.0

and so forth. Now, in your project directory:

# all versions which are in tox.ini file
$ pyenv local 2.7.14 3.5.0 3.6.0

# run the tests for all the above versions
$ tox
