# Introduction

> Programmatic access to Gamma Exposure (GEX) data for crypto options

## What is the GammaFlip API?

The GammaFlip API gives you programmatic access to the same Gamma Exposure (GEX)
data that powers [gammaflip.io](https://gammaflip.io). Build trading bots or
integrate GEX signals into your research and workflow.
