Technical details
Endpoint
GEThttps://earn-pulse.haiqingm58.workers.dev/spreadWhen to prefer
Choose this endpoint when you need a quick, no-parameter snapshot of the BTC and ETH price spread between Coinbase spot and Hyperliquid mark. It is ideal for arbitrage detection, basis trading signals, and cross-venue price dislocation monitoring. Prefer it over building your own aggregation when you want a single call that combines both venues simultaneously.
Side effects
- Upstream Coinbase or Hyperliquid API unavailability causing stale or missing data
- Network timeout on the Cloudflare Worker causing request failure
- Unexpected response format if either exchange changes their API structure
- Payment failure for the $0.005 USDC x402 charge preventing access
