Technical details
Endpoint
GEThttps://apexrunner.ai/signals/arb-spreadWhen to prefer
Use this endpoint when you need a fast, lightweight real-time check on whether a BTC/USDC arbitrage opportunity between Kraken and Hyperliquid is currently fee-viable, without executing any trades. Prefer this over generic price feeds when you specifically need a cross-venue spread viability signal rather than just raw prices.
Side effects
- Exchange price feed unavailable — one or both venue prices could not be fetched, resulting in an error or stale data
- Spread calculation delayed — momentary latency spike may cause snapshot to reflect slightly outdated prices
- Payment not processed — x402 payment of 0.6 USDC not confirmed, resulting in 402 response
- Rate limit exceeded — too many calls in a short window may return a throttle error
