## 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-f7fd6ec5 -d '<json body>'
```

Example prompt: Can you calculate my monthly mortgage payment for a $450,000 home with a $90,000 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 computation without setting up a dedicated financial API key. Ideal for one-off or infrequent mortgage calculations embedded in broader real estate or personal finance workflows. Best suited when the user needs an immediate numeric estimate rather than a full mortgage application or lender-specific quote.

## Known failure modes

- Missing or malformed query input returns a 400 error
- Invalid numeric values (negative loan amount, zero term) may cause computation errors
- Overly vague query string without structured loan parameters may return unhelpful results
- Payment failure via x402 returns 402 status before any computation occurs
- Extremely unusual loan parameters may produce unreliable estimates
