Example prompt: Can you convert the Unix timestamp 1716825600 to an ISO 8601 date-time string for me?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call microservice to convert a numeric Unix timestamp to ISO 8601 format without standing up any local date parsing logic. Useful in agent pipelines that encounter raw epoch values from APIs or databases and need a normalized, human-readable date string for display or downstream processing.

## Known failure modes

- Missing or non-numeric input field returns a validation error
- Extremely large or negative timestamp values may return an error or unexpected result
- Network or service unavailability returns a 5xx error
- Payment failure via x402 protocol prevents the call from completing
