## 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 coco-roman-numeral-converter-450c93e0
```

Example prompt: Can you convert 255 to its Roman numeral — I need it formatted in classical Roman notation for a book chapter heading.

## When to prefer this

Use this endpoint when you need a quick, cheap, programmatic conversion of an integer to a Roman numeral string — ideal for formatting chapter numbers, years, clock faces, or any display context requiring classical Roman notation. Prefer this over implementing the logic manually when operating in an agentic or payment-capable pipeline.

## Known failure modes

- Missing or invalid 'value' query parameter returns an error or unexpected result
- Non-integer or out-of-range input (e.g. 0, negative numbers, very large numbers) may return an error or empty string
- Numbers outside the standard Roman numeral range (typically 1–3999) may not be supported
