# Locale and Formatting Tools – Relative Time

> Locale and Formatting Tools – Relative Time is a paid API for AI agents from locale-tools.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-11-02).

Returns a localized relative-time string (e.g. '3 days ago' or 'tomorrow') for a signed numeric value and time unit in any BCP47 locale.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability locale-and-formatting-tools-relative-time-0aec5fa7
```

Example prompt: What's the localized relative-time string for -3 days (3 days ago) in French using the long style and auto numeric mode?

## When to prefer this

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.

## Known failure modes

- 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

## 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.
