Frequently Asked Questions
What is the BackQuant GEX API?
The BackQuant GEX API provides real-time gamma exposure data for BTC, ETH, and SOL. Retrieve dealer gamma positioning, 0DTE GEX levels, call wall and put wall strikes, the high-volume level (HVL), zero gamma levels, max pain, and ranked strike-level gamma — all via simple REST endpoints with JSON responses.
What gamma exposure data is available?
The GEX endpoints cover strike-level gamma profiles (all-expiry and 0DTE), ranked gamma levels, call wall, put wall, HVL, zero gamma flip level, max pain, and historical GEX data. Options data is aggregated across Deribit, Bybit, OKX, and Binance and updated every 30 seconds.
What other data does the API cover?
Beyond gamma exposure, the API provides 55+ endpoints across options analytics (IV surfaces, term structure, skew, expected move, VRP), perpetual futures (funding rates, open interest, CVD, long/short ratio), liquidation heatmaps, 17 macro indicators (treasury yields, CPI, VIX, credit spreads, net liquidity, FCI), ETF flows (Bitcoin ETF, Ethereum ETF, Grayscale), and equities breadth data.
Which assets are supported?
BTC, ETH, and SOL across all endpoint categories. Options and GEX data is aggregated from Deribit, Bybit, OKX, and Binance. Perpetual futures data covers all major exchanges.
How do I authenticate?
Every request uses an X-API-Key header. You get 2 API keys per account for zero-downtime rotation. Generate and manage keys from your account dashboard.
What are the rate limits?
API Monthly plans include 60 requests per minute. API Yearly plans include 120 requests per minute (2x). Every response includes rate limit headers showing your remaining quota and reset time. Need higher limits? Contact us for a custom plan.
Does the API plan include terminal access?
Yes. Every API plan includes full access to the BackQuant Terminal, TradingView indicators, interactive API documentation, and a usage dashboard.
Can I use the API for commercial purposes?
Standard API plans are for personal, non-commercial use. For commercial use, redistribution, white label solutions, or serving multiple end users, contact us about an Enterprise agreement.
