Crypto GEX API
GEX data via API.
Crypto.
REST endpoints for real-time and historical gamma exposure, dealer positioning, options flow, and IV surfaces - for BTC, ETH, SOL, HYPE, and 100+ crypto assets. Equity GEX lives in the Terminal.
What the crypto GEX API exposes.
The crypto data set from the Terminal, available as REST endpoints - gamma exposure, dealer positioning, chain and surface, perps and funding.
Gamma Exposure
Strike-level GEX, ranked call and put walls, zero-gamma flip level, aggregate GEX, GEX percentile regime, and daily / weekly expiry gamma profiles.
Dealer Positioning
Dealer positioning estimates with regime and sign-change detection in real time.
Historical GEX
Historical time-series endpoints for every crypto asset. Backtest signals, study past regimes, and calibrate systematic strategies on real data.
Options Chain + IV Surface
Full options chain snapshots, implied volatility surfaces, skew and term structure, greek profiles, and max pain per expiry.
Perpetuals + Funding
Cross-venue perp price, OI, funding, liquidations, and CVD for crypto - for context around dealer hedging that spills into perp order books.
Cross-Asset Context
Perp funding, open interest, and market-wide crypto indicators so systematic strategies can condition GEX signals on the broader regime.
What people build with it.
The API is used for alerting bots, systematic strategies, dashboards, and research pipelines on crypto GEX. If you were looking for a crypto GEX bot or an options analytics feed - this is that endpoint.
Alerting bots
Page traders when BTC or ETH crosses zero-gamma, when a large call wall breaks, or when dealer positioning flips sign.
Systematic strategies
Condition entries and stops on the GEX regime, on wall proximity, or on the near-dated gamma sign going into the last hours before expiry.
Dashboards
Aggregate BTC, ETH, and 100+ crypto assets into a single cross-asset GEX view for desks that need dealer positioning at a glance.
Research pipelines
Pull historical GEX at scale to backtest signals, study regime transitions, and calibrate parameter grids for systematic funds.
Coverage.
The API covers crypto. Equity GEX is available in the BackQuant Terminal, not through the API.
Crypto (API)
BTC and ETH options across Deribit, Bybit, Binance, and OKX. SOL and HYPE options on Derive. 100+ crypto assets with perpetual futures data for cross-context. Friday 08:00 UTC daily / weekly / monthly / quarterly expiries.
Equities (Terminal only)
SPX, NDX, and single-name equity gamma exposure are available inside the BackQuant Terminal, not through the API. See the GEX tool for equities coverage.
Crypto GEX API - common questions.
What does the crypto GEX API return?
Strike-level gamma exposure, ranked call and put walls, the zero-gamma flip level, historical GEX time series, gamma percentile regime, dealer positioning, IV surfaces, options open interest, and max pain. Coverage spans BTC, ETH, SOL, HYPE, and 100+ additional crypto assets.
Does the API cover SPX or equity GEX?
No. The API is crypto only - BTC, ETH, SOL, HYPE, and 100+ assets. SPX, NDX, and single-name equity gamma exposure are available inside the BackQuant Terminal, not through the API.
Is there a free tier?
The Terminal subscription includes a 7-day free trial that you can use to evaluate whether the data set works for your use case. API access is a separate tier priced above the standard Terminal subscription - see the API access page for the current pricing.
Can I build a GEX bot or alerting service on the API?
Yes. The crypto GEX data is exposed through REST endpoints so you can pipe it into whatever alerting or execution stack you already run. If you want a ready-made GEX view rather than building one, the Terminal surfaces the same crypto data in a UI (and adds equities coverage).
How is the data delivered - REST, WebSocket, or both?
REST endpoints are the primary delivery mechanism, returning JSON. Historical endpoints support time-range queries. See the API access page for the full endpoint list, rate limits, and authentication details.
Which crypto venues are aggregated for GEX data?
BTC and ETH options data is aggregated across Deribit, Bybit, Binance, and OKX. SOL and HYPE options are covered on Derive. Perpetual futures data (for cross-asset context) is aggregated across Binance, Bybit, and Hyperliquid.
How often does the API data update?
Real-time endpoints update through the session as new options data arrives. Historical endpoints return time-series data at the granularity of the underlying panel. See the endpoint documentation for update cadence per endpoint.
Can I get short-dated expiry gamma data via the API?
Yes. Crypto daily and weekly expiry gamma profiles - for example BTC and ETH Friday 08:00 UTC expiries - are exposed as their own endpoints separate from the aggregate GEX, so you can pull only the near-dated component if that is what your strategy or alerting service needs.
What use cases does the crypto GEX API cover?
Common use cases include: (1) systematic strategies that condition on the zero-gamma flip or wall breaks; (2) alerting bots that page you when BTC or ETH crosses zero-gamma or a large wall breaks; (3) dashboards that need cross-asset crypto GEX views; (4) research pipelines running historical GEX analyses; (5) monitors that reference dealer positioning to size hedges.
How do I authenticate?
API keys issued from the API dashboard once you have an API access subscription. Authentication is via bearer token in the request header. Full authentication docs are on the API access page.
