How this service works
Relative time text such as '3 days ago' or 'tomorrow' for a signed value and unit in any locale.
Output
Returns a JSON object containing the formatted relative-time string (e.g. 'hace 3 días'), the resolved locale, direction (past/future), decomposed parts with types and values, ICU/CLDR/Unicode version info, and optional degradation or disclaimer flags.
Example use cases
Multilingual social feed timestamps
“I need to show post timestamps as relative text in a user's language — can you format -2 hours in Japanese using the short style?”
Localized 'days until' event countdown
“Our event is in 14 days — give me the relative-time text for +14 days in German with the long style and always-numeric mode.”
Narrow relative-time labels in compact UI
“I'm building a compact UI and need a narrow relative-time label for -1 week in Spanish — can you get that for me?”
Technical details
Endpoint
GEThttps://locale-tools.x402tookit.com/relative-time?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need standards-compliant, ICU/CLDR-backed relative-time formatting across diverse locales — especially for multilingual apps, internationalised UIs, or any scenario where locale-sensitive output (auto 'yesterday' vs '1 day ago', RTL languages, narrow vs long styles) matters and rolling your own Intl.RelativeTimeFormat is impractical.
Side effects
- Missing required 'value' or 'unit' parameters returns a 400-level error
- Invalid or unrecognized BCP47 locale tag may fall back to a default locale with a degraded flag set
- Unsupported unit strings (not one of second/minute/hour/day/week/month/quarter/year) cause validation errors
- Value exceeding absolute magnitude of 1e9 is rejected
- Payment not included or insufficient USDC triggers a 402 Payment Required response
