# Duration Format & Parse

> Duration Format & Parse is a paid API for AI agents from units-convert.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Formats a number of seconds into a human-readable duration string or parses a duration text like '1d 3h 20m' back into numeric components (seconds, minutes, hours, days).

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 duration-format-parse-75b771cf
```

Example prompt: How long is 7565 seconds in a human-readable format like hours and minutes? Also give me the breakdown in days, hours, minutes, and seconds.

## When to prefer this

Use this endpoint when you need to convert a raw number of seconds into a display-friendly duration string, or when you need to parse a human-entered duration expression (like '1d 3h 20m') into numeric components. Prefer this over manual string formatting when you need consistent, multi-unit breakdowns (days/hours/minutes/seconds) and a ready-to-display human string without writing your own parsing logic.

## Known failure modes

- Missing both 'seconds' and 'text' query params — returns an error or empty result
- Invalid duration text format that cannot be parsed — may return null component values
- Negative seconds value — behavior undefined
- Non-numeric input for 'seconds' param — likely returns an error

## How this service works

Turn seconds into a readable duration (2 h 5 min) or parse one like '1d 3h 20m' back into seconds, minutes and hours.

## Output

Returns a structured object with the duration expressed as a human-readable string (e.g. '2 h 5 min'), a clock format, and numeric breakdowns for days, hours, minutes, and seconds. Also includes a summary field and source echo.
