alphagbm-vol-surface

name	alphagbm-vol-surface
description	3D volatility surface analysis mapping implied volatility across strikes (moneyness) and expirations. Shows whether options are cheap or expensive at every point on the surface. Returns surface grid data, ATM term structure, skew by expiry, and surface anomalies. Use when: checking if IV is expensive, analyzing term structure, finding mispriced options, understanding volatility dynamics. Triggers on: "vol surface AAPL", "is NVDA IV expensive", "volatility term structure SPY", "surface analysis TSLA", "IV surface META", "show me the vol surface".

AlphaGBM Volatility Surface

Prerequisites

• API Key: Set env ALPHAGBM_API_KEY (format agbm_xxxx...).
• Base URL: Default https://alphagbm.zeabur.app. Override with env ALPHAGBM_BASE_URL.

What This Skill Does

Builds a 3D volatility surface for any optionable ticker, mapping implied volatility across two dimensions -- strike price (moneyness) and time to expiration. Identifies where options are cheap, expensive, or anomalous relative to the surface.

Key Outputs

Output	What It Shows
Surface Grid	IV at each (strike, expiry) coordinate -- the full 3D map
ATM Term Structure	How at-the-money IV changes across expirations (front-month vs. back-month)
Skew by Expiry
