I tried to get stock price data using Quandl API, which provides various financial data of the world by API. I would like to share with you how to use the Quandl API service and your personal impressions of the service. (Because I am stingy, I will introduce the features within the range that can be used for free.)
Quandl API Quandl official website: https://www.quandl.com/
$ pip install Quandl
Tokens can be obtained by registering an account with Quandl.
In the sample code, the stock price of Coca-Cola Company is acquired.
Of course, you can also get data on Japanese stocks.
For example, if you want to get the stock price of Toyota, you can get it by changing `'WIKI / KO'``` to `'TSE / 7203'```.
sample_quandl.py
import quandl
quandl.ApiConfig.api_key="MY_TOKEN"
data=quandl.get('WIKI/KO')
print(data)
I was able to acquire the stock price from 1962 to 2018. However, as a result of executing it in 2020, it seems that the latest stock price cannot be obtained because only the data up to 2018 can be obtained. (It seems that the latest data cannot be obtained if Japanese stocks are also free versions.)

It seems that the latest stock price data cannot be obtained if the Quandl API is the free version. I wanted to create a service that uses the latest stock price data, so I would like to find another API service that can get the latest version of the stock price.
