How this service works
Gloom is a free, open-source finance terminal for desktop and TUI with charts, news, filings, portfolios, alerts, and plugins.
Output
Returns a JSON array of futures contract objects, each containing: the as-of date, a human-readable label (e.g. 'VIX 2026-10'), the contract price, price change, ticker symbol, daily volume, currency, quote unit (e.g. volatility points), expiration date, and open interest. The array covers all available expirations for the requested root, forming the complete futures term structure curve.
Example use cases
VIX term structure analysis
“Show me the entire VIX futures curve today — all expirations with their prices, volume, and open interest so I can see whether the market is in contango or backwardation.”
Crude oil forward curve monitoring
“Get me the full futures curve for crude oil (CL) — I need every contract month listed with current prices and open interest to spot where the market is most liquid.”
Automated volatility spread tracking
“Fetch the latest futures curve for VX and tell me the price spread between the front-month and the second-month contract so I can track the roll cost.”
Technical details
Endpoint
GEThttps://api.gloom.sh/v1/futures/curves/%7Broot%7D?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need the full term structure (all contract expirations) for a futures root symbol in a single call — especially for volatility products like VIX (VX) or other CME/CBOE-listed futures. Prefer this over single-contract endpoints when analyzing contango/backwardation, roll cost, or curve shape. It is well-suited for open-source finance terminal users and AI agents that need structured, machine-readable futures market data with open interest and volume across all maturities.
Side effects

- Market closed or data unavailable for a session may return stale or missing data
