## 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 47620-unit-converter-api-57d6ba93
```

Example prompt: Convert 10 miles to kilometers for me.

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call unit conversion without integrating a heavy SDK. It is especially useful when dealing with historical Russian units (verst, pood, arshin, zolotnik, sazhen, funt, vershok) not found in most converters, or when you need conversion plus category labeling in a single structured JSON response.

## Known failure modes

- Unsupported unit code returns an error or null result
- Missing required query parameters (value, from, to) cause a bad request response
- Mismatched unit categories (e.g. converting miles to kilograms) return an error
- Non-numeric value parameter causes a parse error
- Payment failure (x402) if USDC not provided

## How this service works

Convert any value between units: length (m/km/mi/ft/in/yd/nmi, plus Russian verst/sazhen/arshin/vershok), mass (g/kg/lb/oz/tonne, plus Russian pood/funt/zolotnik), area (m2/ft2/km2/acre/hectare) and temperature (C/F/K). Pass ?value=<n>&from=<unit>&to=<unit>. Returns the converted value and the unit category.

## Output

A JSON object containing the converted numeric value and a string identifying the unit category (e.g. 'length', 'mass', 'area', 'temperature'), along with an 'ok' boolean status flag.
