# Numora Mortgage Payment Calculator

> Numora Mortgage Payment Calculator is a paid API for AI agents from numormor.netlify.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

Calculates monthly mortgage payments and related financial figures given a loan principal, annual interest rate, and loan term in months

## Facts

- Endpoint: POST https://numormor.netlify.app/api/financial/mortgage
- Price: $0.1/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 numora-mortgage-payment-calculator-cd7b952b -d '<json body>'
```

Example prompt: Can you calculate the monthly mortgage payment on a $450,000 home loan at a 6.75% annual interest rate over 360 months (30 years)?

## When to prefer this

Use this endpoint when you need a pure deterministic mortgage payment calculation with no external data dependencies — ideal for agents that need fast, cheap, reproducible financial math without calling a full banking API or financial data service. Best suited for straightforward amortization math rather than complex scenarios requiring live rate quotes or credit checks.

## Known failure modes

- Missing required fields (rate, months, principal) returns validation error
- Non-positive principal or rate may cause computation error
- Zero or negative months will produce invalid result
- Payment failure via x402 micropayment returns 402 status before computation

## How this service works

100 pure math computation endpoints for AI agents. Statistics, financial math, linear algebra, equation solving, calculus, number theory, sequence generation, and unit conversions. Zero external dependencies. x402 micropayments on Base.

## Output

Returns a JSON object with a success flag, a human-readable computation description, and a result object containing the computed mortgage figures such as monthly payment amount derived from the principal, rate, and loan term.
