Product
Two ways to deploy Volptima's volatility fitter.
Both products deliver the CVI (Convex Volatility Interpolation) fitter, a non-parametric, arbitrage-free volatility surface fitting engine based on convex optimization. CVI has no restriction on the number of parameters and works out of the box across underlyings and market regimes with sensible defaults.
Beyond CVI, the library also provides a fast American option pricer (supporting discrete cash dividends) with smooth greeks.
SaaS
Cloud API access via a Python SDK. Fitting runs on Volptima infrastructure.
- Python SDK with typed objects
- Cloud API
- Cognito authentication + API key
- Built-in Plotly dashboard
- No deployment or maintenance
Best for evaluation, light usage or latency-tolerant workflows
Local Binaries
The Rust engine runs in your infrastructure, with bindings available in all main languages.
- Everything in SaaS, plus:
- In-process Rust fitter (no network)
- Python, C/C++, ... bindings
- Simple JSON-in / JSON-out interface
- License file for offline use
- Linux (x86_64) and Windows (x86_64)
Best for production systems and high-throughput fitting
