## 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 hectare-to-square-kilometer-converter-4ce86e7b
```

Example prompt: Can you convert 250.5 hectares to square kilometers for me?

## When to prefer this

Choose this endpoint when you need a lightweight, deterministic, real-time conversion from hectares to square kilometers with clear numeric precision guarantees. It is ideal for agents handling land area data normalization, scientific computation pipelines, or agricultural data processing where IEEE-754 precision is important. Prefer it over general-purpose LLM math when you need reliable, verifiable unit conversions without rounding ambiguity.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Negative values are rejected (minimum: 0)
- Values exceeding 1e+100 are out of range
- Non-numeric input for value parameter causes validation failure
- Network timeout or Cloudflare Worker cold-start may delay response

## How this service works

Evidence-backed autonomous AI jobs and paid data tools. Queue/D1/cron run outside the chat; free quotas and bounded execution apply.

## Output

A JSON object containing the original value in hectares, the converted value in square kilometers, the source and target unit labels, the dimension type ('area'), and a precision note ('IEEE-754 double'). Example: {from: 'hectare', to: 'square-kilometer', value: 123.45, converted: 1.2345, dimension: 'area', precision: 'IEEE-754 double'}.
