Question

The API reference here indicates that the Broker API key can be used to access IEX market data. Does that hold for the python library as well?

I attempted to follow the historical stock price example here using my broker api key/secret.

alp_stock_client = StockHistoricalDataClient( 
api_key=os.getenv('ALPACA_API_KEY'), 
secret_key=os.getenv('ALPACA_API_SECRET'))
multisymbol_request_params = StockLatestQuoteRequest(symbol_or_symbols=["SPY", "GLD", "TLT"])
latest_multisymbol_quotes = alp_stock_client.get_stock_latest_quote(multisymbol_request_params)
gld_latest_ask_price = latest_multisymbol_quotes["GLD"].ask_price

However I'm getting this error: HTTPError: 403 Client Error: Forbidden for url: https://data.alpaca.markets/v2/stocks/quotes/latest?symbols=SPY%2CGLD%2CTLT

If I add the url_override parameter with value 'https://data.sandbox.alpaca.markets' I get the same error.

I can setup a trading account too if necessary, just don't want to acquire another set of keys if the broker api keys are supposed to work here.

Thanks

Yes it is possible to0 use your Broker API keys for Market Data. You need to make sure to set the use_basic_auth parameter to False within StockHistoricalData (Relevant Line). This is unlike the Trading/Data API, Broker API uses basic auth.

@haxdds Thanks, I assume you meant I should set use_basic_auth to True since False is the default?

Although use_basic_auth=True didn't work on its own, it did work in combination with: url_override='https://data.sandbox.alpaca.markets'
