How this service works
Returns the next open and next close time of a stock exchange or futures market after a given time.
Output
Returns the next open datetime and next close datetime for the requested market after the specified (or current) time, expressed as ISO 8601 timestamps with timezone offsets.
Example use cases
Pre-trade session timing for algorithmic trader
“I'm about to submit orders — when does XNAS next open and close? Use current time as the reference.”
Cross-timezone market open alert
“My team is in Tokyo and wants to know when the London Stock Exchange (XLON) will next open and close — can you look that up from right now?”
Holiday gap detection for CME equity futures
“It's 2025-11-27T15:00:00Z — when will the CME equity futures market (CME_EQUITY) next open and what time will it close after that?”
Technical details
Endpoint
GEThttps://market-hours-api.onrender.com/v1/next?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to know precisely when a specific exchange or futures market will next open or close — ideal for scheduling automated trades, alerts, or workflows around market sessions. Prefer this over a general 'is the market open now?' check when forward-looking timing is required.
Side effects
- Invalid or unsupported market code returns an error — only XNYS, XNAS, XLON, XETR, XSWX, XTKS, XHKG, XSHG, XASX, CME_EQUITY, EUREX_INDEX are accepted
- Malformed 'at' timestamp (not ISO 8601 with offset) may produce a parsing error
- If the market is on an extended holiday closure, the next open may be far in the future
- Payment failure (x402) if USDC balance is insufficient
