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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file 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. |

How to install
mdr add starchild-ai-agent/official-skills/massive-options-data@sha256:942f334662cd3e08The line at the top of this page pins the label v1.3.1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
