## 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 omniapi-mortgage-calculator-7c4016fc -d '<json body>'
```

Example prompt: Can you calculate the monthly mortgage payment on a $450,000 home loan with a 6.75% interest rate over 30 years and a $90,000 down payment?

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call mortgage computation without setting up a dedicated financial API key. Ideal for agents handling one-off or infrequent mortgage calculations paid in USDC via x402, especially when already using OmniAPI for other finance or crypto endpoints in the same workflow.

## Known failure modes

- Missing required query parameter returns 400 error
- Invalid numeric values for loan amount or rate may return calculation error
- Extremely unusual loan terms (e.g. 0% rate or 0 term) may produce unexpected results
- Payment processing failure via x402 returns 402 before computation
- Malformed request body returns generic API error
