    Let us start to be acquainted with how to use Yahoo Finance API.\u00a0<\/span><\/p>\n

      \n
    1. The first point to be discussed is the OAuth protocol for authorization and authentication. Yahoo Finance Public API supports two primary profiles – server-side application and client-side application.
      \n1.1\u00a0<\/span>The initial step is to receive the Yahoo network credentials<\/span>
      \n1.2 Next is to obtain the authorization Yahoo Finance API URL<\/span>
      \n1.3 The third is to provide the authorization to access the data<\/span>
      \n1.4 And finally need to get the access token and refresh token of the Yahoo Finance API key
      \n<\/span><\/li>\n
    2. The second important point is using Yahoo Finance API for Analytics and reporting.
      \n2.1 The sample request for       receiving data<\/a> on the sessions
      \n2.2\u00a0<\/span>The sample request for       obtaining data<\/a> about an event\u00a0<\/span>
      \n<\/span><\/i>2.3\u00a0 <\/span>The <\/span>sample<\/span> for       adding<\/a> Yahoo Finance API parameters to an event\u00a0<\/span>
      \n2.4 The sample request for obtaining       real time data<\/a>
      \n2.5 The sample request for obtaining       revenue analytics data<\/a>
      \n<\/span><\/li>\n
    3. Thirdly, let’s discuss how to use Yahoo Finance Restful API – Monetization Reporting API. You need to interact with the API through HTTPS Get requests. You need to acquire a Yahoo Finance Rest API token.
      \n<\/span>3.1 If you want to query the monetization data, then you need to select the appropriate Yahoo Finance Data API requests from       here<\/a><\/span>
      \n3.2 To aggregate the metrics, you need to use time grain and dimension<\/span>
      \n3.3 If you want to provide a date\/time range then use the dateTime<\/span>
      \n3.4 If you want to filter out the dimension values then use Filters<\/span>
      \n3.5 If you want to sort out the columns in metrics then the code is as       below<\/a>\u00a0<\/span><\/li>\n
    4. If you want to leverage the Yahoo Finance API limits or rate limits, then you can restrict to a few 100 requests per day. If you want to increase the limit, then you need to go for an additional Yahoo Finance API license by subscribing to Market data plans or a proxy plan where you can increase the rate limit to 10,000 API calls in a day.<\/span><\/li>\n
    5. Next is to understand how to install the Yahoo_Fin library,
      \n<\/span>5.1 the command is <\/span>pip install yahoo_fin<\/span>
      \n5.2 The command for installing requests_html is pip install requests_html<\/span>
      \n5.3 The library has two modules stock_info and options<\/span><\/li>\n
    6. The method for retrieving the finance fundamental data like the Price to Earnings
      \n<\/span>An illustration of the results returned is below::<\/span>quote_table = si.get_quote_table(“aapl”, dict_result=False)
      \n<\/span>quote_table
      \n<\/span>{‘1y Target Est’: 314.55,
      \n<\/span>’52 Week Range’: ‘174.52 – 327.85’,
      \n<\/span>‘Ask’: ‘323.97 x 1300’,

      \n<\/span>‘Quote Price’: 321.8500061035156,
      \n<\/span>‘Volume’: 20185053.0}
      \n<\/span>Get the P\/E ratio by:
      \n<\/span>quote_table[“PE Ratio (TTM)”]
      \n<\/span>25.29<\/span><\/li>\n
    7. If you want to receive the dividends that you are expecting from a stock, then use the get_quote_table() function as part of Yahoo Finance Stock API <\/span>quote_table = si.get_quote_table(“aapl”)quote_table[“Forward Dividend & Yield”] ‘3.28 (1.02%)’<\/span><\/li>\n
    8. If you want to download the trading data like <\/span>historical open, high, low, close, and volume data sampled at regular intervals then use the get_data() method
      \n<\/span>si.get_data(\u201caapl\u201d)<\/li>\n
    9. Among the Yahoo Finance API codes, the one to get the market cap is <\/span>si.get_quote_table(“aapl”)[“Market Cap”] <\/span>‘1.39T’<\/li>\n
    10. The 52 week average volume can be retrieved from the following code
      \n<\/span>si.get_quote_table(“aapl”)[“Avg. Volume”]
      \nsi.get_quote_table(“aapl”)[“Volume”]
      \n49012080.0
      \n7274811.0<\/li>\n
    11. To download the data from the income statement, you need to use get_income_statement() <\/span>income_statement = si.get_income_statement(“aapl”)<\/li>\n
    12. To download the data from the balance sheet, you need to use get_balance_sheet()
      \n<\/span>balance_sheet = si.get_balance_sheet(“aapl”)<\/span><\/li>\n
    13. To download the data from the cash flow statement, you need to use get_cash_flow() <\/span>cash_flow_statement = si.get_cash_flow(“aapl”)<\/span><\/li>\n
    14. To download the options data, you need to use the code <\/span>import yahoo_fin.options as ops<\/span><\/li>\n<\/ol>\n
