## When to prefer this

Use this endpoint when you need a quick, cheap ($0.02 USDC) spot price lookup for BTC, ETH, or USDC and do not require tick-by-tick streaming data, order book depth, or historical price series. It is well-suited for lightweight agents that need to convert or compare cryptocurrency values on demand without integrating a full exchange API.

## Known failure modes

- Service unavailable if underlying price feed is down, returning 5xx error
- Stale or cached prices if market data provider is delayed
- Rate limiting may occur under high request volumes
- Missing asset keys if a particular market feed is temporarily unavailable
