Frequently Asked Questions
Everything you need to know before using the API.
Q
What does the AI narrative include?
A plain-English read of the gamma regime, day-over-day GEX change, key levels in context, notable OI flow, vanna/charm interpretation and an outlook, with the structured numbers backing each line.
Q
What's the difference between GEX, DEX and VEX?
GEX is gamma exposure (how hedging dampens or amplifies moves), DEX is delta exposure, VEX is vanna exposure (delta's sensitivity to vol). Together they explain dealer hedging more completely than GEX alone.
Q
Which plan do I need for the narrative?
GEX (single expiry) and key levels are Free; the AI narrative, exposure summary and full-chain GEX are Growth.
Q
Which names are supported?
Any US equity or ETF with listed options; index symbols require Basic or higher.
Growth

Single-name positioning as a read, not a chart: full-chain GEX and DEX with walls per expiry, the one-call exposure summary and the AI narrative.
- Full-chain GEX and DEX with walls per expiry, 6,000+ single names
- Exposure summary - regime, flip and hedging pressure in one call
- AI narrative - the positioning story, not just the chart
- 15-second freshness - swing entries on current positioning
When Alpha instead: vanna and charm surfaces for the second-order flows, the raw tape for attribution, and minute replay of how similar positioning resolved historically.
