Alpha Vantage randomly says Invalid API Call

问题 I have code in python that periodically fetches data for a particular ticker. import pandas as pd import time def intraday(ticker, interval, key): """ Returns interday data """ url = f'https://www.alphavantage.co/query?function=TIME_SERIES_INTRADAY&symbol={ticker}&interval={interval}&apikey={key}&datatype=csv' df = pd.read_csv(url) df = df.reset_index() while True: print(intraday('AAPL', '1min', key) time.sleep(60) The problem that I face, is that this code works well most of the time.

问题 I’ve got an Alpha Vantage API key and am having issues with parsing the data. I’m unsure how to approach parsing the data as there are JSON and CSV options. The CSV seems to be a download, I’m not trying to manually download a new file every time I want to update the stock price.

Unfortunately, Yahoo has stopped this service so I have to fix it. 回答1: You can use Alpha Vantage the
