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 pennyrail-time-conversion-f9d6e043 -d '<json body>'
```

Example prompt: Convert 1704067200 Unix epoch seconds to an ISO 8601 datetime string in UTC for me.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-use time conversion without setting up a full datetime library or service. Ideal for AI agents needing occasional timestamp normalization, format conversion, or unit transformation as part of a broader workflow, especially in environments where adding a dependency is impractical. At $0.001 per call it is cost-effective for low-volume or ad-hoc conversions.

## Known failure modes

- Invalid or unparseable input time value — returns error indicating unrecognized format
- Missing required 'input' object in request body — returns 400 validation error
- Unsupported conversion pair — returns error if the source/target format combination is not recognized
- Payment not included or insufficient — returns 402 Payment Required
- Ambiguous time string with no format hint — may return unexpected result or error
