An API key from the service settings is required

Real-time SPX (0DTE) options dealer market-structure as a machine-readable feed for agents. Over MCP (Streamable HTTP) or a REST v1 mirror on one key: current dealer positioning - call/put walls, gamma flip, net GEX and gamma-profile depth, scored pressure points, a forecast band, strike activity, VIX term structure with IV/skew, realized-vol stats - plus a dealer-regime label (CHOP / TREND / BREAKOUT) recomputed roughly every 10 seconds during market hours. Historical replay dates, per-day timelines, compressed regime segment tapes, and event webhooks (regime transitions, wall changes, zero-gamma flip) are included. Informational/educational data for your own analysis - not financial advice, and not the Defiance ZDTE ETF or a fund.
