Technical details
Endpoint
GEThttps://kronossignals.com/api/v1/cex-premium/btcWhen to prefer
Use this endpoint when you need a fast, point-in-time signal of US/institutional crypto demand by measuring the Coinbase price premium over global exchanges. Ideal for trading agents, market monitors, or macro dashboards that want a reliable demand-skew indicator without storing or querying historical data. Prefer over raw price feeds when you specifically need inter-exchange premium analysis rather than absolute price levels.
Side effects
- Asset not listed on Coinbase — endpoint only covers supported assets like BTC/ETH/SOL etc.
- Exchange data unavailable — one or more composite exchanges may be temporarily unreachable, affecting median calculation
- Payment failure — x402 micropayment of $0.02 USDC not completed or wallet lacks funds
- Rate limiting — too many calls in a short window may result in 429 responses
- Stale data — real-time feeds may have brief latency spikes during high volatility
