What you now have access to

Your Greeks pipeline is live.

01  Full coverage, ticking continuously

Independently computed Greeks across ~6,000 underlyings — equities, ETFs and index options, refreshed continuously during market hours.

02  Vendor-compatible URL patterns

Gateway speaks the wire format of nine common vendors. If you're already using Alpaca, AlphaVantage, Intrinio, LiveVol, MarketData.app, Orats, Polygon.io, ThetaData or Tradier — swap the host and your existing code works unchanged.

03  See it live — NVDA at-the-money

Once Gateway is running, paste this URL in any browser to see Greeks for NVDA's at-the-money chain rendered as an HTML table:

http://localhost:2112/l1/greeks?root=NVDA&center=atm&format=html
