Python Example:
pythonCopyEditimport requests
api_key = 'YOUR_API_KEY'
symbol = 'AAPL'
url = f'https://www.alphavantage.co/query?function=TIME_SERIES_DAILY&symbol={symbol}&apikey={api_key}'
response = requests.get(url)
data = response.json()
print(data)
Step 4: Choose the Right Function for Your Needs
