The Options Flow & Dealer Positioning API: A Complete Map of Every Endpoint
FlashAlpha exposes the full options flow and dealer-positioning surface as one REST API, settled exposure (GEX, DEX, VEX, CHEX, levels, max pain), live flow-adjusted analytics, the raw trade tape, cross-symbol scans, 0DTE, and a plain-English narrative. This is the map: every endpoint, the question it answers, its tier, and a link to the deep dive.
If you are looking for an options flow API, a dealer positioning API, a GEX/DEX/VEX/CHEX exposure suite, an unusual options activity feed, a 0DTE analytics endpoint, or a plain-English options market read, they are all here, under one key, one base URL (https://lab.flashalpha.com), and one auth header (X-Api-Key). This page is the index; each endpoint links to its own deep-dive guide and reference docs.
First, the One Distinction That Matters: Settled vs Live
Everything in the dealer-positioning surface falls into one of two families, and picking the right one is the single most important decision:
Exposure (settled)
Flow Analytics (live)
Route prefix
/v1/exposure/*
/v1/flow/*
Based on
Settled open interest snapshots
Settled OI + intraday flow simulator
Use when
You want the official, stable positioning picture
You want the intraday, flow-adjusted picture before OI re-settles
Five endpoints that round out the surface, each previously under-documented and now with a full guide:
Portfolio & Sector GEX Basket, aggregate GEX/DEX/VEX/CHEX across up to 50 symbols in one call. The question no single-ticker tool answers: is the whole basket short gamma?
Net Dealer Premium, one signed number for whether dealers are net long or short premium right now, off the full VWAP-weighted tape.
Real-Time Gamma Squeeze Detection, the per-bar dealer hedge delta-dollars on today's 0DTE chain that turns "squeeze" from a vibe into a measurement.
Plain-English GEX Narrative, the exposure read as grounded sentences, built for LLM agents and automated alerts.
Day-Over-Day OI Changes, per-contract open-interest deltas that show where positioning was added or unwound overnight, the read volume can't give you.

The whole dealer-positioning surface under one API key
Settled exposure, live flow, the raw tape, 0DTE, and plain-English narrative. One base URL, one header.
/v1/exposure/* endpoints compute dealer positioning from settled open interest, the official, stable picture that goes stale after the intraday OI re-snapshot. /v1/flow/* endpoints recompute the same concepts intraday against a flow-driven OI simulator, so they stay current through the session. Most concepts (GEX, levels, pin risk, 0DTE) exist in both forms; pick settled for stability, flow for freshness.
Start with /v1/exposure/gex and /v1/exposure/levels for the gamma map and key strikes, add /v1/exposure/narrative for a plain-English read, and use /v1/exposure/basket to aggregate across a sector or book. For intraday freshness, add the Flow Analytics equivalents (/v1/flow/summary, /levels, /dealer-risk). For the trade tape behind it all, the Alpha-tier raw flow endpoints and /dealer-premium.
The settled Greeks (GEX/DEX/VEX/CHEX) and max pain start on Basic. Levels, the exposure summary/sheet/basket/narrative, term structure, OI diff, the Growth-tier Flow Analytics, and 0DTE flow are on Growth. The full live flow analytics, the raw flow tape, flow signals, dealer premium, and cross-symbol scans are on Alpha. See the tiers table above and the tier pricing guide.
The options flow and dealer-positioning surface is broad, but it resolves to one decision and a handful of questions: settled or live, and then which question, walls, regime, pin, premium, unusual activity, squeeze, or the plain-English read. This map is the index to all of it. Bookmark it, pick the layer your strategy needs, and drill into the guide for that endpoint. Everything runs under one key, one base URL, and one header, so you can move across the surface without re-plumbing your integration.
