Technical details
Endpoint
GEThttps://workspace-x402-paywall.onrender.com/spread?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need real-time, multi-venue SOL price and spread data in a single call, especially for arbitrage detection, trading signal generation, or market monitoring. It is uniquely suited for agents that need both CEX and DEX venue coverage simultaneously with a notional-adjusted spread estimate, and that can pay micro-fees via x402 on Base or Solana without requiring an API key or subscription.
Side effects
- Missing or invalid notional parameter may return an error or default to a zero/null notional
- Payment not received (402 response) if x402 USDC payment on Base or Solana is not attached
- Venue data may be stale or incomplete if one or more exchanges are unreachable at query time
- Low venues_reporting count if exchanges are temporarily unavailable, reducing spread reliability
- Service may be unavailable if the Render deployment is cold-starting or down
