Yes, there is an undocumented BATCH_STOCK_QUOTES that lets you pass in a comma seperated list of ticker symbols.
It seems like the endpoint BATCH_STOCK_QUOTES is not working anymore.
Example HTTP GET request (use your apikey instead of xxx):
https://www.alphavantage.co/query?function=BATCH_STOCK_QUOTES&apikey=xxx&symbols=MSFT,AAPL,FB
Response:
{
"Meta Data": {
"1. Information": "Batch Stock Market Quotes",
"2. Notes": "IEX Real-Time",
"3. Time Zone": "US/Eastern"
},
"Stock Quotes": [
{
"1. symbol": "MSFT",
"2. price": "119.1900",
"3. volume": "10711735",
"4. timestamp": "2019-04-09 14:39:53"
},
{
"1. symbol": "AAPL",
"2. price": "199.9100",
"3. volume": "27681098",
"4. timestamp": "2019-04-09 14:39:56"
},
{
"1. symbol": "FB",
"2. price": "177.1800",
"3. volume": "14088849",
"4. timestamp": "2019-04-09 14:39:50"
}
]
}
I found this looking at the source of this javascript api wrapper:
