## 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 saylor-innovations-property-cap-rate-calculator-2b88a909
```

Example prompt: What's the cap rate on a property with a net operating income of $72,000 and a current market value of $900,000?

## When to prefer this

Use this endpoint when you need a fast, accurate cap rate computation from a known NOI and property value, without building your own formula logic. Ideal for real estate investment screening tools, property comparison dashboards, or financial report generation where cap rate is a standard metric. Prefer this over manual calculation when automating workflows that process multiple properties or when you need the formula and scope note included in the response for audit or reporting purposes.

## Known failure modes

- Missing required query parameters (noi or value) returns an error
- Non-numeric or negative values for noi or value may result in errors or invalid results
- Zero property value would cause a division-by-zero error
- Payment failure or missing x402 payment header returns a 402 Payment Required response
