## When to prefer this

Use this endpoint when you need a single, real-time spot price for a specific Binance-listed trading pair with minimal latency. Prefer this over order book or 24h stats endpoints when you only need the current price, not depth or historical context. Ideal for quick price checks, portfolio valuations, or threshold-based triggers in agent workflows.

## Known failure modes
