Get current average price for a symbol. Returns the weighted average price over the last 5 minutes.

This is a straightforward market data retrieval endpoint that reads public pricing information from Binance without modifying any state or triggering any transactions. No authentication appears necessary based on the server description stating public market data requires no API key.
