## 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 agenttools-area-unit-converter-c3e8a474
```

Example prompt: Convert 5.75 acres to square meters for me.

## When to prefer this

Use this endpoint when an agent needs a reliable, on-demand area unit conversion between any combination of standard area units (metric and imperial) without implementing conversion math locally. Ideal for real estate, agriculture, construction, or geospatial workflows where area values need to be presented in different units.

## Known failure modes

- Missing required query params (value, from, to) returns a 400 error
- Unsupported unit codes outside the allowed enum (km2, ha, acre, m2, ft2, mi2, cm2) return an error
- Non-numeric value input causes a validation error
- Payment failure via x402 protocol blocks the request

## How this service works

Convert area units: square millimeters, centimeters, meters and kilometers, hectares, acres, square feet and square miles. Use this when an agent needs to square meters, feet, acres, hectares.

## Output

Returns the numeric result of the area conversion from the specified source unit to the target unit, along with metadata about the conversion (input value, from/to units, and converted result).
