Is it possible to get LTP and Volume of all the symbols in an exchange?

Alpaca Market Data

I am testing an algorithm that compares all stocks with one another and picks the best one for trade. In the algorithm I compare all the stocks with each other. For this I need list of all the symbols, LTP and current volume. I am using NodeJS. Is it possible to do this, or what is the closest I can get to full fill this requirement ?

Im using python but I grab all stocks like:

stockUniverse = self.alpaca.list_assets(status=‘active’,asset_class=None)
for stock in stockUniverse:
if stock.exchange==‘NASDAQ’ and stock.tradable==True:
self.allStocks.append(stock.symbol)

then I check volume in a loop like:
for stocks in self.allStocks:
stocks = self.alpaca.get_bars(stocks, TimeFrame.Day,
start=pd.Timestamp(‘now’).date()-timedelta(days=3),
end=pd.Timestamp(‘now’).date(),
limit=3,
adjustment=‘raw’
).df
if stocks.iloc[0][‘volume’]>100000:
self.allStocks_use.append(stocks)
