Output
A JSON object containing the queried coin symbol, a list of exchanges (Kraken, Coinbase, Gemini, Bitstamp, Bitfinex, Gate.io, KuCoin, MEXC) each with bid, ask, last price, 24h volume in both USD and base units, and premium vs median percentage.

Best execution price finder
“I want to buy some SOL — which exchange is currently offering the best ask price? Pull the live order book data across Kraken, Coinbase, Gemini, and the others.”
Real-time crypto market snapshot

Technical details
Endpoint
GEThttps://saylorinnovations.com/api/crypto/exchanges/spread?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a cross-exchange view of a cryptocurrency's current market price, including bid/ask spread, 24h volume, and arbitrage signals — all in one call. It covers 8 major exchanges simultaneously and normalizes USDT quotes to USD, making it superior to querying individual exchange APIs separately. Ideal for arbitrage detection, best-execution routing, and market monitoring dashboards.
Side effects
- Unknown or unsupported coin symbol returns an error or empty exchange list
- One or more exchanges may be temporarily unresponsive, reducing exchanges_responding count
- USDT conversion rate unavailable may cause null values on USDT-quoted pairs
- Network timeouts to upstream exchange APIs may return stale or null bid/ask data
- Payment failure (402) if USDC balance is insufficient or x402 header is missing
