Colleagues
For years, I have been downloaded stock prices using something like:
require("jsonlite")
cmd <-
"https://query1.finance.yahoo.com/v7/finance/quote?fields=symbol,longName,regularMarketPrice,regularMarketTime,regularMarketChange&formatted=false&symbols=AAPL";
fromJSON(cmd)
Yesterday, this stopped working -- the message is:
Error in open.connection(con, "rb") :
cannot open the connection to
'https://query1.finance.yahoo.com/v7/finance/quote?fields=symbol,longName,regularMarketPrice,regularMarketTime,regularMarketChange&formatted=false&symbols=AAPL'
In addition: Warning message:
In open.connection(con, "rb") :
cannot open URL
'https://query1.finance.yahoo.com/v7/finance/quote?fields=symbol,longName,regularMarketPrice,regularMarketTime,regularMarketChange&formatted=false&symbols=AAPL':
HTTP status was '401 Unauthorized'
When I paste that code directly into a browser, I get:
{"finance":{"result":null,"error":{"code":"Unauthorized","description":"Invalid
Crumb"}}}
I need the most recent closing price and the today's real-time price. What
other options exist to download prices for multiple stocks?
