​
What it returns

For a specific expiration, this endpoint returns:
  • GEX per strike — dealer gamma exposure at each strike price
  • Gamma profile curve — total gamma exposure modeled across all price levels (not just listed strikes)
  • Key markers — gamma flip, max gamma strike, major walls
  • Zones — price regions where dealer hedging is expected to accelerate (volatility triggers)
This is the most detailed GEX endpoint — it’s what powers the “GEX by Strike” chart on gammaflip.io.

TOTAL aggregates all expirations for the given coin. Useful for getting an “all-positioning” view; individual expiration views are more precise for timing-specific trades.

​
Errors

​
400 invalid_exchange
error
Exchange not recognized.
​
404 no_data
error
No data for this coin/exchange/expiration combination. Common cause: the expiration doesn’t exist on that exchange (use /expirations/ first).
