Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/svi/eth/usdWhen to prefer
Choose this endpoint when you need a complete, arbitrage-free implied volatility surface for ETH options across all expiries in a single call, especially when cryptographic attestation (Ed25519) of the data is required for on-chain or trustless applications. Prefer over raw per-exchange IV feeds when a smooth, model-consistent SVI surface is needed for options pricing, Greeks computation, or risk management.
Side effects
- Payment required (402) if x402 USDC payment not provided or invalid
- Stale or unavailable market data if underlying exchanges are unreachable
- Invalid or missing attestation signature if signing service is degraded
- Rate limit exceeded if too many requests per period
