x402
SiteCheck Timezone Lookup & Conversion is a paid API for AI agents from api.sitecheck-api.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-15).
Returns current local time, UTC offset, and DST status for an IANA timezone, with optional conversion between two timezones

How this service works
The current time in an IANA time zone (its UTC offset and whether DST applies) and, with time and to, the conversion of a local time from one zone to another. Computed in the Worker with the runtime's time zone data; no outside call.
Output
Returns a JSON object with the current local time, UTC offset, DST boolean, and a checkedAt timestamp for the requested IANA zone. If a conversion is requested (providing a source time and target zone), also returns the converted local time and UTC timestamp for both the source and destination timezones.
Example use cases
Schedule international meeting time
“I need to schedule a meeting at 3:00 PM in America/Chicago on April 10 2026 — what time would that be for someone in Asia/Singapore?”
Check current local time in a city
“What is the current local time and UTC offset in Australia/Sydney? Is it currently observing daylight saving time?”
Convert event time for global announcement
“Our product launch is set for 2026-06-15T09:00 in Europe/London — convert that to America/Los_Angeles so I can tell the West Coast team what time to tune in.”
Technical details
Endpoint
GEThttps://api.sitecheck-api.workers.dev/api/timezone?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need authoritative IANA-based timezone resolution — including current local time, UTC offset, DST status, and optionally converting a specific local datetime between two IANA zones. Prefer this over generic time APIs when accuracy of DST transitions and IANA zone naming is important, or when you need the full conversion round-trip (source zone → UTC → target zone) in a single call.
Side effects
- Invalid or unknown IANA timezone string returns an error — must be a valid IANA zone like 'Europe/Istanbul', not an abbreviation like 'EST'
- Missing required 'zone' query parameter returns a validation error
- Malformed 'time' parameter (not in ISO-like format) may cause conversion to fail
- Conversion requires both 'time' and 'to' parameters; providing only one may yield a partial or error response
