Alpha Vantage API not returning Nasdaq quotes

Question

The Alpha Vantage API doesn't deliver quotes for the NASDAQ Index (anymore?). All other indizes that I'm interested in seem to work like a charm.

For example calling the following URL (API Key masked) will deliver the quote for the S&P (symbol ^GSPC):

https://www.alphavantage.co/query?symbol=%5EGSPC&apikey=123456789&outputsize=compact&datatype=csv&function=GLOBAL_QUOTE

I already came across this post, that describes the exact thing. The solution using the symbol ^IXIC doesn't seem to work however (neither IXIC). All I get is {}.

Are some indizes like NASDAQ just not supported or is there any other symbol I have to take.

Answer 1

It's the other way around, they support stock tickers, and if they happen to have indexes, that's a bonus.

To quote the site:

Alpha Vantage APIs are grouped into four categories: (1) Stock Time Series Data, (2) Physical and Digital/Crypto Currencies (e.g., Bitcoin), (3) Technical Indicators, and (4) Sector Performances. 

It doesn't mention indexes.
