## 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-eeb226f1 -d '<json body>'
```

Example prompt: Convert '3:45 PM EST' on January 15, 2025 to UTC in ISO 8601 format.

## When to prefer this

Use this endpoint when you need a lightweight, pay-per-use time conversion service without setting up a dedicated time library or SDK, especially within agentic workflows that already use x402 micro-payment infrastructure. Ideal for one-off conversions in automated pipelines.

## Known failure modes

- Missing or malformed input time value returns a 400-level error
- Unsupported time format or timezone identifier results in a conversion error
- Payment failure or insufficient USDC balance causes a 402 Payment Required response
- Ambiguous time string without sufficient context may return an incorrect or unexpected conversion
