## 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-unix-timestamp-to-iso-8601-converter-021d31be -d '<json body>'
```

Example prompt: Can you convert the Unix timestamp 1700000000 to ISO 8601 format for me?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call microservice to convert a single Unix timestamp to ISO 8601 without setting up your own date library or server-side logic. Ideal for AI agents that occasionally encounter epoch times in API responses and need them normalized on the fly. At $0.001 USDC per call it is cost-effective for infrequent, single-value conversions.

## Known failure modes

- Missing or non-numeric 'input' field returns a validation error
- Very large or out-of-range epoch values may produce invalid or null results
- Non-integer floats may be truncated or rejected depending on server handling
- Network or cold-start latency on Vercel serverless may cause occasional timeouts
