ALPHAGBM_API_KEY (format agbm_xxxx...).https://alphagbm.zeabur.app. Override with env ALPHAGBM_BASE_URL.Provides a comprehensive Greeks dashboard for any single option contract or multi-leg position. Calculates first-order and second-order sensitivities, and generates scenario heatmaps showing how Greeks change as price and IV move.
| Greek | Order | What It Measures |
|---|---|---|
| Delta | 1st | Price sensitivity -- how much does the option move per $1 in the underlying? |
| Gamma | 1st | Delta sensitivity -- how fast does delta change? (acceleration) |
| Theta | 1st | Time decay -- how much value does the option lose per day? |
| Vega | 1st | IV sensitivity -- how much does the option move per 1% change in IV? |
| Rho | 1st | Interest rate sensitivity -- how much does the option move per 1% rate change? |
| Charm | 2nd | Delta decay -- how does delta change as time passes? (delta-theta cross) |
| Vanna | 2nd | Delta-vol cross -- how does delta change as IV moves? |
| Volga | 2nd | Vega convexity -- how does vega change as IV moves? |
For multi-leg positions, the skill aggregates Greeks across all legs and shows:

# AlphaGBM Greeks
## 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
Provides a comprehensive **Greeks dashboard** for any single option contract or multi-leg position. Calculates first-order and second-order sensitivities, and generates scenario heatmaps showing how Greeks change as price and IV move.
### Greeks Covered
| Greek | Order | What It Measures |
|-------|-------|-----------------|
| **Delta** | 1st | Price sensitivity -- how much does the option move per $1 in the underlying? |
| **Gamma** | 1st | Delta sensitivity -- how fast does delta change? (acceleration) |
| **Theta** | 1st | Time decay -- how much value does the option lose per day? |
| **Vega** | 1st | IV sensitivity -- how much does the option move per 1% change in IV? |
| **Rho** | 1st | Interest rate sensitivity -- how much does the option move per 1% rate change? |
| **Charm** | 2nd | Delta decay -- how does delta change as time passes? (delta-theta cross) |
| **Vanna** | 2nd | Delta-vol cross -- how does delta change as IV moves? |
| **Volga** | 2nd | Vega convexity -- how does vega change as IV moves? |
### Position-Level Analysis
For multi-leg positions, the skill aggregates Greeks across all legs and shows:
- **Net Greeks**: Total delta, gamma, theta, vega for the combined position
- **Greeks per unit of capital**: Normalized by margin requirement or net debit
- **Risk concentration**: Which leg contributes most to each Greek
## API Endpoints
