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 read on the options market, they all live behind one key, one base URL (https://lab.flashalpha.com), and one auth header (X-Api-Key).
This post is the index. Each endpoint links to its own deep-dive guide.
pip install flashalpha
from flashalpha import FlashAlpha
fa = FlashAlpha("YOUR_KEY")
gex = fa.gex("SPY")

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 you will make.
| Exposure (settled) | Flow Analytics (live) | |
|---|---|---|
| Route prefix | /v1/exposure/* |
/v1/flow/* |
| Based on | Settled open interest snapshots | Settled OI plus an intraday flow simulator |
| Use when | You want the official, stable picture | You want the flow-adjusted picture before OI re-settles |
| Goes stale | After the intraday OI re-snapshot (~10:30 ET) | Updates continuously with flow |
The two are paired. Most exposure concepts (GEX, levels, pin risk, 0DTE) exist in both a settled and a live form. Pick settled for stability, flow for freshness. With that in hand, here is the full map.
1. Exposure & Greeks (settled positioning)
Per-strike Greeks, key levels, and term structure, computed from official open interest.
| Question | Endpoint | Tier |
|---|---|---|
| Where is dealer gamma by strike? | /v1/exposure/gex |
Basic+ |
| What is dealer directional bias? | /v1/exposure/dex |
Basic+ |
| How does hedging react to vol & time? |
/v1/exposure/vex, /chex
|
Basic+ |
| Where are the call/put walls & flip? | /v1/exposure/levels |
Growth+ |
| Where is the pinning strike? | /v1/maxpain |
Basic+ |
| One unified per-strike Greek sheet? | /v1/exposure/sheet |
Growth+ |
| Which expiry drives the regime? | /v1/exposure/term-structure |
Growth+ |
| What positioning changed overnight? | /v1/exposure/oi-diff |
Growth+ |
| Is a sector or my book short gamma? | /v1/exposure/basket |
Growth+ |
| Give me the read in plain English | /v1/exposure/narrative |
Growth+ |
2. Live Flow Analytics (flow-adjusted positioning)
The same concepts, recomputed intraday against the flow-driven OI simulator. Fresher than settled exposure during the session.
| Question | Endpoint | Tier |
|---|---|---|
| What's the headline flow shift & direction? | /v1/flow/summary |
Growth+ |
| Where are the live walls & flip? | /v1/flow/levels |
Growth+ |
| What's the live pin risk? | /v1/flow/pin-risk |
Growth+ |
| How has dealer risk shifted on flow? | /v1/flow/dealer-risk |
Alpha+ |
| Full live GEX/DEX surface & OI state? |
/v1/flow/gex, /dex, /oi, /live
|

3. The raw flow tape & cross-symbol scans
Trade-level flow and market-wide ranking. The "what is actually printing, and where" layer. Alpha plan.
| Question | Endpoint | Tier |
|---|---|---|
| Recent prints, blocks, cumulative net flow? | /v1/flow/options/{symbol}/... |
Alpha |
| Where's the unusual activity, ranked? |
/v1/flow/options/outliers, /leaderboard
|
Alpha |
| Scored unusual options activity? | /v1/flow/signals |
Alpha |
| Are dealers net long or short premium? | /v1/flow/options/{symbol}/dealer-premium |
Alpha |
| Equity (stock) flow tape & bars? | /v1/flow/stocks/{symbol}/... |
Alpha |
4. 0DTE (same-day expiry)
Same-day options drive a disproportionate share of intraday price action. These endpoints are scoped to today's expiry.
| Question | Endpoint | Tier |
|---|---|---|
| Live 0DTE regime snapshot? | /v1/flow/zero-dte/snapshot |
Growth+ |
| 0DTE regime over time (chartable)? | /v1/flow/zero-dte/series |
Growth+ |
| Is a gamma squeeze building right now? | /v1/flow/zero-dte/hedge-flow |
Growth+ |
| 0DTE analytics (settled)? | /v1/exposure/zero-dte |
Growth+ |
Newest additions
Four endpoints that round out the surface:
- 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 - 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.

FAQ
What's the difference between exposure and flow endpoints? /v1/exposure/* computes positioning from settled open interest, the stable picture that goes stale after the intraday OI re-snapshot. /v1/flow/* recomputes the same concepts intraday against a flow-driven simulator, so they stay current through the session.
Which endpoints do I need for dealer positioning? 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 book. For intraday freshness, add the Flow Analytics equivalents.
Is the whole surface on one plan? No. Settled Greeks and max pain start on Basic. Levels, the summary/sheet/basket/narrative, term structure, OI diff, Growth-tier Flow Analytics and 0DTE flow are on Growth. The full live flow analytics, the raw tape, signals, dealer premium and cross-symbol scans are on Alpha.
