## 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 square-mile-to-square-foot-converter-ae5a5d64
```

Example prompt: Convert 0.75 square miles to square feet for me.

## When to prefer this

Use this endpoint when you need a quick, precise, programmatic conversion from square miles to square feet without setting up local math. It is ideal for agents handling real estate, land surveys, urban planning, or geographic data where area units need to be normalized. Prefer this over manual computation when auditability and consistent IEEE-754 precision matter.

## Known failure modes

- Missing required 'value' query parameter returns an error
- Value below 0 or above 1e100 is rejected by schema validation
- Non-numeric value for 'value' parameter causes a 400-class error
- Network or worker timeout may return 5xx if the Cloudflare Worker is unavailable
- Payment not provided or insufficient USDC balance results in 402 Payment Required

## 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 and unit ('from': 'square-mile'), the converted result in square feet ('converted'), the target unit ('to': 'square-foot'), the dimension type ('area'), and the precision standard used ('IEEE-754 double').
