Options

OPEX calendar with per-expiry context

Curated calendar of upcoming options expirations with everything needed for OPEX-day workflows in one call:

  • Token + ISO date + DTE + classification (daily / weekly / monthly / quarterly) + is_anchor flag.
  • OI block: call_oi, put_oi, total_oi, pcr, notional_oi_usd (= total_oi × spot, since each crypto options contract is 1 unit of underlying).
  • IV block: atm_iv, skew_25d, put_25d_iv, call_25d_iv.
  • Gamma block: net_gex, call_resistance, put_support (computed per expiry from the strike × expiry heatmap), and max_pain ({strike, value} from the shared per-expiry cache used by /v2/gex/max-pain and /v2/options/expiry- summary).

next_anchor points at the closest monthly/quarterly. Filter with ?types=monthly,quarterly for the institutional-roll view or ?horizon= to bound the look-ahead window.
