Coinbase spot price in USD for up to ten crypto assets. Use this for a current crypto price. Returns an explicit per-symbol error rather than a guessed number when an asset is unavailable. Costs $0.005 USDC per call via x402 on Base; an unpaid call returns the payment challenge instead of data, and a call that returns no data is never settled so it costs nothing. Equivalent HTTP route: GET /crypto.
