}About the vixcentral.com API
The VIXCentral API provides 3 endpoints for accessing VIX futures term structure data and volatility market indicators. The get_current_vix_curve endpoint returns live contract month prices alongside VIX, VIX9D, VIX3M, and VIX6M index values. Historical endpoints let you retrieve the full futures curve for any single trading day back to 2007 or pull a time series across a date range up to 31 calendar days at a time.
Current VIX Futures Curve
The get_current_vix_curve endpoint returns a curve array where each object contains a month label, last price, and settle price for each active VIX futures contract. An indicators object accompanies the curve with four index values: VIX, VIX9D, VIX3M, and VIX6M. The response also includes a date field showing the UTC timestamp of retrieval, which lets you confirm data freshness. This endpoint takes no input parameters.
Historical Single-Day and Range Lookups
The get_historical_vix_curve endpoint accepts a single date parameter in YYYY-MM-DD format and returns the vix_index closing value alongside a futures_curve array of objects with month_index (1-based contract position) and price. Historical coverage starts from 2007, and only trading days with recorded data are returned. If you need multiple days, get_historical_range accepts start_date and end_date parameters and returns a data array where each entry contains a date, a vix value, and a futures array of contract prices. The range is capped at 31 calendar days per request; the truncated boolean in the response signals when that limit was exceeded.
Response Shape Notes
Current and historical endpoints use slightly different contract representations. The current curve uses named month strings (e.g. "Aug25") while historical endpoints use integer month_index values. The range endpoint returns futures prices as a plain array of numbers ordered by contract month, without named month labels. These structural differences are worth accounting for when merging data across endpoints in your pipeline.

Does VIXCentral have an official developer API?+
What does `get_historical_range` return when the date range includes weekends or holidays?+
data array. The start_date and end_date fields in the response reflect the requested boundary dates regardless of whether those specific dates had trading activity.What happens if I request a range longer than 31 days in `get_historical_range`?+
truncated field to true in the response. To cover a longer period, issue sequential requests with non-overlapping start_date and end_date values.Does the API return options data, open interest, or volume for VIX futures contracts?+
Is intraday or tick-level VIX futures data available?+
date field in get_current_vix_curve records the UTC retrieval timestamp, but the price data itself reflects the most recent published curve rather than a tick stream. You can fork this API on Parse and revise it to add intraday polling logic if needed.
