I have a list of stock tickers and for each ticker I need today's close price and yesterday's close price.
I could use (have used) Yahoo Historical Data API by sending
GET requests of the following form:
But I have to make a separate data request for each ticker. For large lists of tickers this approach is very network intensive, very slow, and very prone to communication errors.
Is there a data source API which I could send a list of tickers (in any format) and receive a list of today's close price & yesterday's close price for each ticker sent?
(A single 1D array in the request and a single 2D array in the response.)
This question was intended as an API referral, not an example code request.
