Downloading Historical Data from the API

Yahoo Finance allowed users to download historical data via an API. The API was shut down in 2017. However, there are still unofficial APIs that do the same work. If you use one of these APIs, be aware that they can violate Yahoo’s Terms of Service.

Below is the sample code you could have used in the Yahoo Finance API and will still work in the unofficial APIs.

Arguments

Below are the arguments you will use to build the code needed to retrieve historical data from the API:

  • ticker: case insensitive ticker of a stock
  • start_date: date the data begins in format mm/dd/yyyy
  • end_date: date the data ends in format mm/dd/yyyy
  • index_as_date: {True, False}. The default will be True. The dates of the records will be set as the index. If false, the dates return in a separate column.
  • Interval: time period to sample data. “1d” = daily; “1wk” = weekly; “1mo” = monthly

How to Download Historical Data From Yahoo Finance API

Once you’ve established what your arguments will be, you can build your code. Below is an example code for retrieving weekly historical data from Amazon.

from yahoo_fin.stock_info import get_data()

amazon_weekly= get_data("amzn", start_date="12/04/2009", end_date="12/04/2019", index_as_date = True, interval="1wk")

amazon_weekly

You can edit the code to include your preferred arguments, and the API will retrieve your needed historical data. When ready, copy the code into the API and run it.

Be advised that because the APIs are not official, they may not return all of the data or may provide inaccurate data. Since the Yahoo Finance API is defunct, there is no way to improve this.
