## 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 nexusapi-mortgage-calculator-4f2fcc82 -d '<json body>'
```

Example prompt: What would my monthly mortgage payment be on a $450,000 home with a 20% down payment, a 30-year fixed loan at 6.75% interest rate?

## When to prefer this

Use this endpoint when an agent needs a quick, pay-per-call mortgage calculation without setting up API keys or managing authentication. Suitable for on-demand financial planning queries where a user wants to estimate home loan costs without integrating a full mortgage platform.

## Known failure modes

- Missing required loan parameters returns a validation error
- Invalid numeric values (e.g. negative loan amount) may return a 400 error
- Extremely high or low interest rates outside normal range may produce unexpected results
- Generic input schema means poorly structured query strings may return empty or incorrect results
- Service downtime or payment failure returns 402 or 5xx errors
