## When to prefer this

Choose this endpoint when you need real-time Coinbase bid/ask prices specifically for BTC, SOL, or SHIB quoted in USDC and want a lightweight, pay-per-call micropayment model ($0.001 USDC). Prefer alternatives if you need prices for other assets, fiat currency quotes, historical data, or OHLCV candlestick data.

## Known failure modes

- Invalid or unsupported pair parameter (e.g. ETH-USDC) returns an error — only BTC-USDC, SOL-USDC, SHIB-USDC are supported
- Missing 'pair' query parameter causes a bad request response
- Payment failure (x402) if USDC micropayment of $0.001 is not completed
- Coinbase upstream unavailability may cause stale or missing price data
- Network timeout if the host (werner.ddns.net) is unreachable (DDNS-hosted service)
