Parameters

Required Parameters

Name	Type	Location	Description
symbol	string	path	Underlying equity ticker symbol (e.g. SPY, AAPL).

Optional Parameters

Name	Type	Location	Description
minDte	integer	query	Minimum DTE horizon filter (alias: dteMin, default 0).
maxDte	integer	query	Maximum days to expiration (alias: dteMax; default 60; max 730). In GEX, maxDte=0 filters for 0DTE contracts (same-day expiration) for backward compatibility; see also zeroDte=true.
zeroDte	boolean	query	Filter strictly for 0DTE (same-day expiration) contracts. In GEX, maxDte=0 also denotes 0DTE contracts for backwards compatibility. zeroDte=true with maxDte > 0 returns 400 invalid_parameter.
