Company name to ticker using Yahoo Finance API endpoint

ticker.py

def get_ticker(company_name):
    yfinance = "https://query2.finance.yahoo.com/v1/finance/search"
    user_agent = 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/108.0.0.0 Safari/537.36'
    params = {"q": company_name, "quotes_count": 1, "country": "United States"}

    res = requests.get(url=yfinance, params=params, headers={'User-Agent': user_agent})
    data = res.json()

    company_code = data['quotes'][0]['symbol']
    return company_code

@gpetrone84 works for me. get_ticker("Tesla") returns "TSLA". The trick is to make sure your company_name is generic enough. I tried "Tesla Corporation" and it didn't work.

Thank you for this!
I'm currently doing CS50 pset9 Finance. The distribution code only gives the ability to search by Symbol.
I wanted a way to search company name and retrieve the symbol. I tried Alpha Vantage and IEX API but AV would return different symbols and IEX used to work but as of 22 July 2023, started returning random gibberish names.
Using your code, I was able to do what I wanted and this was way cleaner and simpler. Even better, no api key needed for yfinance so I don't need to keep creating new accounts like I did with IEX.

@bruhbruhroblox Thank you very much!

Thanks @leftmove
