## 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-nano-unix-timestamp-to-iso-8601-date-converter-681a205b -d '<json body>'
```

Example prompt: Convert the Unix timestamp 1716422400 to an ISO 8601 date string for me.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-call microservice to convert Unix timestamps to ISO 8601 dates without setting up a local utility or library. Ideal for agent workflows that need on-demand time format conversion as part of a data pipeline.

## Known failure modes

- Missing required 'input' field returns a validation error
- Non-numeric input causes a type error
- Extremely large or negative numbers may produce out-of-range date errors
- Payment failure (402) if USDC balance is insufficient
