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 agent402-tools-duration-parser-humanizer-62857d92 -d '<json body>'
```

Example prompt: How many seconds is '1d4h30m'? Parse that duration string for me and give me the total seconds.

## When to prefer this

Use this endpoint when you need to convert human-readable duration strings (e.g. '1d4h', '90s', '2h30m') to seconds for scheduling or computation, or when you need to display a raw seconds count as a readable label. Prefer this over manual parsing logic when the duration format may vary.

## Known failure modes

- Invalid or unrecognized duration string format — returns error indicating unparseable input
- Missing 'value' field in request body — returns validation error
- Negative seconds value may produce unexpected output or error
- Ambiguous or empty input string returns parsing error

## How this service works

Parse a duration like "2h30m" / "1d4h" / "90s" to seconds, or humanize a number of seconds.

## Output

Returns either the total number of seconds corresponding to the parsed duration string, or a human-readable duration string (e.g. '2 hours, 30 minutes') when given a raw seconds value as input.
