World Time API.
Worldwide access to timezone information, current time, IP to timezone conversion, geolocation data (IP to geo) and more.
# endpoints
- GET /timezone — list all timezones (537)
- GET /timezone/{tz} — time for a timezone
- GET /ip — time for the calling IP
- GET /ip/{ip} — time for any IP
- GET /geo — geolocation for the calling IP
- GET /geo/{ip} — geolocation for any IP
# why this exists
worldtimeapi.org was the go-to for years — until it got too slow to rely on, and eventually shut down. The replacements made you choose: fast and closed, or open and unmaintained. Never both.
This is neither. Source-available, p99 under 40ms, drop-in compatible with worldtimeapi.org's endpoints.
# pricing
- $0 — 20,000 req/mo. More than enough for hobby projects.
- $5+ — paid tiers up to 1M+ req/mo. For developers and teams looking to scale.
# what people say
“Switched off worldtimeapi.org by changing one URL. None of my services needed a code change. Wish I'd done it sooner.”
— Ravi K., full-stack dev
“I run a lot of scheduled scrapers across a bunch of time zones. This handles all the timezone math for me without ever being the thing that breaks.”
— Mason T., web automation
“Flaky NTP meant our devices disagreed about the time. Now they all ask one place and get one answer.”
— Kira A., smart-home
