get_session — Everything FirmTape measured for ONE finished SPX session: OHLC and VWAP, the zero-gamma flip and how often price crossed it, call/put walls, the hold band, net-gamma percentile, ATM IV at the open.
get_level_history — How the SPX dealer-positioning levels MOVED across recent finished sessions: the zero-gamma flip, call resistance and put support day by day, each session's change from the one before, and summary statistics for the window (flip range, net drift, mean daily movement, how often price closed above the flip).
get_levels — Only the dealer-positioning level set for one finished SPX session: zero-gamma flip, call resistance, put support, hold band — plus where the session closed relative to them.
get_gex_profile — The SPX dealer gamma LADDER for one minute of a finished session: gamma by strike around spot, the level set, and the heaviest strikes.
search — Search FirmTape for documents about SPX dealer positioning: the explainer pages, the dated research measurements, and the archive of finished trading sessions.
fetch — Retrieve the full text of one FirmTape document by the id `search` returned: `session:YYYY-MM-DD` for a finished trading session, `page:/path` for an explainer or research page.
options_strategy_test — Test an SPX 0DTE options strategy — a condor, strangle, straddle or any leg set — against every session in the FirmTape archive on real quotes and real settlement.
