Duration API — oanor API marketplace

Duration API

Work with ISO-8601 durations — the PnYnMnDTnHnMnS strings (P3Y6M4DT12H30M5S, PT1H30M) used across calendars, scheduling, video metadata, billing periods and APIs. Parse a duration into its components and a total in seconds and milliseconds; format a number of seconds (or individual year/month/week/day/hour/minute/second fields) back into a canonical ISO-8601 string; humanise any duration into readable text ("1 hour and 30 minutes"); and measure the exact duration between two instants (ISO timestamps or unix epochs) as both an ISO-8601 string and a precise second count. Years and months use documented calendar averages and are clearly flagged as approximate. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 5 endpoints. Distinct from date/time parsing and relative-time ("3 hours ago") formatting.

 Relative Time & Locale Date API — oanor API marketplace

Relative Time & Locale Date API

Humanise timestamps and format dates for any locale and timezone using full ICU. The relative endpoint turns an instant into a localised relative phrase against now (or a given reference time) — "3 hours ago", "vor 3 Stunden", "in 2 days", "il y a 5 minutes" — automatically choosing the best unit from seconds to years. The format endpoint renders a localised date/time string (e.g. "mardi 2 juin 2026 à 15:30" or "2026年6月2日 22:30:00"), honouring the locale (BCP 47), a named IANA timezone, the chosen date and time styles (full/long/medium/short) and 12/24-hour preference, and returns a parts breakdown for custom displays. Pass dates as ISO 8601 or unix timestamps. Everything is computed locally with no network calls. Ideal for internationalised UIs, activity feeds, notifications, comments and dashboards. A relative-time and locale date formatter — distinct from current-time-in-a-timezone (time), the UTC parse/token toolkit (datetime) and number/currency formatting (numberformat). No upstream key, no cache.

 World Cities API — oanor API marketplace

World Cities API

Search a database of 33,000+ cities worldwide (population 15,000+) from GeoNames. Find cities by name, country and minimum population, look up a city by id, or find all cities near a coordinate (radius search). Each city includes coordinates, region, population, timezone and elevation — ideal for autocompletes, location pickers, store locators and geo dashboards.

api.oanor.com/cities-api

 Time Zones API — oanor API marketplace

Time Zones API

Every IANA time zone with its coordinates and country, enriched in real time with the current UTC offset, abbreviation, DST status and local time (computed from the system ICU time-zone database — always up to date, no key). Look up a zone by name, list all zones for a country, search zones by name, or find the nearest IANA zones to any latitude/longitude. 418 zones across 247 countries/territories. Ideal for scheduling, calendars, logistics, geo apps and any feature that needs to map a place or coordinate to the right time zone and current local time.
