Vol surface, any strike

Single-point or bulk interpolated quotes. Specify strike, moneyness, or delta — the API solves for the right point and returns vol, price, and Greeks.

Constant-maturity history

Daily time series at any fixed tenor and strike. Built for backtesting — one call returns the full date range. No more day-by-day loops.

σ

Realized vol + spot

Rolling realized vol (√365 annualized), daily spot prices per session, IV-RV gap analysis. Drop-in inputs for vol-risk-premium strategies.

3 sessions per day

Asia close (05:00 ET), London close (12:00 ET), US close (16:00 ET). Same surface across sessions, so you can see how skew evolves intra-day.

Ask Quanta

Quanta, our AI vol analyst, takes plain-English questions and returns tables and charts inline — vol skews, term structures, forwards, the works. No SDK needed for one-off lookups.

π

Python SDK + REST

pip install cryptovol. Typed responses, retry/backoff, plan-aware errors, optional pandas. Or curl directly if you prefer.
