FlashAlpha provides an options analytics API designed for real-time and historical options data analysis across more than 6,000 equities, ETFs, and CME index futures (ES, NQ). The platform focuses on delivering analytics such as gamma exposure (GEX), delta exposure (DEX), vanna exposure (VEX), charm exposure (CHEX), and three-dimensional implied volatility surfaces. It supports per-tick computation and is backtestable to the minute since 2018, enabling users to replay analytics at any historical point within that period.

The API includes endpoints for a variety of advanced options metrics and calculators, such as gamma flip levels, call/put walls, 0DTE magnet, narrative GEX analysis with regime outlook, volatility risk premium (VRP), skew profiles, hedging scenarios, max-pain, and flow-signed GEX, which distinguishes dealer gamma exposure based on actual traded positions rather than open interest or decay heuristics. It offers specialized calculators for gamma exposure, Black-Scholes Greeks, implied volatility, and optimal position sizing using the Kelly criterion.

FlashAlpha is accessible via a REST API, with example usage provided for both curl and a Python SDK. The platform advertises rapid onboarding, with users able to go live in under a minute, and provides documentation and a playground for testing API calls. 5 million options structures per second.

The service is used by independent quantitative analysts and volatility traders. FlashAlpha offers a free tier and provides access to its full endpoint stack for both options and futures analytics. Users can explore data for any supported ticker and tailor the platform to their trading style and needs.
