Technical details
Endpoint
GEThttps://api.myceliasignal.com/oracle/svi/btc/usdWhen to prefer
Use this endpoint when you need a mathematically rigorous, arbitrage-free implied volatility surface for Bitcoin options, specifically parameterized using the Gatheral 2004 SVI model with smooth smile interpolation. Prefer this over raw per-strike IV endpoints when you need consistent, interpolatable surface data suitable for derivatives pricing models. The Ed25519 signed attestation makes it suitable for on-chain or trust-minimized applications requiring verifiable vol data.
