PyGenphi

Standard Datasource of DeFi research

create a new Python project using PyGenphi

mkdir PyGenphiDemo
cd PyGenphiDemo

git init

pipenv install --dev
# activate venv
pipenv shell
# install PyGenphi
pipenv install PyGenphi==0.10.0

Note: run command pipenv install PyGenphi==0.10.0 within existing PyGenphiDemo directory with lower version of PyGenphi will auto upgrade PyGenphi to v0.10.0

IMPORTANT NOTE FOR IPython(Jupter/anaconda3) users:

You may get an error report like:

~/opt/anaconda3/lib/python3.7/asyncio/base_events.py in run_forever(self)
    519         self._check_closed()
    520         if self.is_running():
--> 521             raise RuntimeError('This event loop is already running')
    522         if events._get_running_loop() is not None:
    523             raise RuntimeError(

RuntimeError: This event loop is already running

To fix this error, you may need install library nest_asyncio with command:

pipenv install nest_asyncio

Then use it before PyGenphi lib:

import nest_asyncio
from PyGenphi import *

nest_asyncio.apply()

dataservice APIs

Note: constructor of class Client now support optional parameters scheme host port api_key, Client() will connect to URL with prefix http://127.0.0.1:80/, and Client(scheme='https', host='192.168.1.1', port=8081, api_key='<your_api_key>') will connect to URL with prefix https://192.168.1.1:8081/ with HTTP header APIKey for authentication

IMPORTANT NOTE: for PyGenphi 0.8.0+, value of all amount related field no long parsed from type str to Decimal by PyGenphi, please do this with Decimal(<amount>) if needed(import library decimal with code from decimal import *).
