massive-options-data skillA
massive-options-data is agent-read markdown (skill) from starchild-ai-agent/official-skills: US options data: chain snapshots, contracts, trades, quotes, greeks, IV, OI. Use when pulling option chains or contract metrics for analysis (e.g. AAPL Jan calls, SPY chain, NVDA IV, weekly puts)..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# Massive Options Data
Data supply layer for US options market data. Wraps the Massive (Polygon)
options REST endpoints with a thin, predictable Python interface.
This skill does NOT generate strategies, signals, rankings, or trading
advice — it only exposes options data.
## Plan: Developer — REAL field availability
We are on **Massive Options Developer ($79/mo)**. Build your callers against
what's actually present in the API responses:
| Field | Developer returns? | Notes |
|---|---|---|
| `details.*` (ticker, strike, expiration, type) | ✅ | Always present. |
| `implied_volatility` | ✅ | Per contract, 15-min delayed. |
| `greeks` (delta, gamma, theta, vega) | ✅ | Per contract, 15-min delayed. |
| `open_interest` | ✅ | Per contract, previous session. |
| `day.{open,high,low,close,volume,vwap}` | ✅ | **Option prices** (previous session OHLC), 15-min delayed. |
| `underlying_asset.ticker` | ✅ | Always present. |
| `underlying_asset.price` | ✅ | **Current underlying price**, 15-min delayed. |
| `last_trade` (price, size, timestamp) | ✅ | **Last trade**, 15-min delayed. |
| `last_quote` (bid/ask) | ❌ | **Still not returned** on Developer. Cannot calculate real-time spread. |

Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
