## 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 hectares-to-square-millimeters-converter-5e3d811a
```

Example prompt: How many square millimeters are in 3.5 hectares?

## When to prefer this

Use this endpoint when you need a quick, programmatic conversion from hectares to square millimeters without implementing the math locally, especially in automated agent workflows that already handle x402 micropayments. Ideal for precise scientific or engineering calculations requiring millimeter-scale area results from hectare-scale inputs.

## Known failure modes

- Missing 'value' query parameter returns an error or bad request response
- Non-numeric or malformed value causes a conversion failure or error response
- Payment not provided or failed causes a 402 Payment Required response
- Extremely large or small numeric values may cause overflow or precision issues

## How this service works

Convert hectares to square millimeters (area). Pass ?value=N.

## Output

Returns the numeric equivalent of the input hectare value expressed in square millimeters, allowing precise area unit conversion between the two scales.
