How this service works

Example use cases
Options trader rolling VIX positions
“I need to roll my VIX futures before expiry — can you give me the next 3 VIX expiration dates from today so I know when to act?”
Volatility strategy scheduling
“I'm planning a volatility trading strategy for the next quarter. What are the next 12 VIX options expiration dates starting from 2025-07-01?”
Risk manager checking upcoming VIX settle
“Can you tell me when the next VIX expiration is this month? I need the exact holiday-adjusted Wednesday date.”

Endpoint
GEThttps://market-calendar-api.onrender.com/v1/vix-expiry?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need precise, holiday-adjusted VIX expiration dates rather than naively computing the third Wednesday of the month. Ideal for derivatives trading workflows, volatility strategy planning, and risk management systems that must account for US market holidays.
Side effects
- Invalid date format returns a 400 error
