## When to prefer this

Choose this endpoint when you need a real-time, point-in-time snapshot of the best bid and ask for INJ-USD specifically, rather than full order book depth, historical candles, or ticker data. It is ideal for quick pre-trade checks, spread calculations, or arbitrage comparisons where only the top-of-book prices matter.

## Known failure modes

- Invalid product ID returns an error — only valid Coinbase USD product IDs are accepted
- Market closed or low-liquidity periods may return empty or stale order book levels
- Network or upstream Coinbase API errors may result in timeouts or 5xx responses
- Payment failure (insufficient USDC) will block the request at the x402 payment layer
