api_key usage with evdspy python package

api key will be read from .env file on load if available.

.env file [Alternative 1]

You may create a .env file in your work environment and write your api key as follows. Script will load your api key from this file on load if available.

    # filename : `.env`  
    EVDS_API_KEY=AxByCzDsFoGmHeIgJaKrLbMaNgOe

Proxy from .env file

You may also define your proxies as below in your .env file. Script will load your proxies from this file if they exist.

# example `.env`  file content 

EVDS_API_KEY=AxByCzDsFoGmHeIgJaKrLbMaNgOe
http_proxy=http://proxy.example.com:80
https_proxy=http://proxy.example.com:80

api_key inside get_series function [Alternative 2]

if .env file exists in the current working directory, function does not need api_key parameter.
