# Numora Loan Amortization Calculator

> Numora Loan Amortization 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).

Computes a full loan amortization schedule given principal, annual interest rate, and loan term in months

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-loan-amortization-calculator-c21b9434 -d '<json body>'
```

Example prompt: Can you calculate the full amortization schedule for a $250,000 home loan at a 6.5% annual interest rate over 360 months — I want to see how much goes to principal vs interest each month?

## When to prefer this

Choose this endpoint when you need a pure server-side, dependency-free amortization calculation without integrating a full financial library. Ideal for AI agents that need structured loan payment data on demand, with micropayment-per-call pricing that avoids subscription overhead. Prefer over spreadsheet tools or external financial APIs when you need clean JSON output in an automated pipeline.

## Known failure modes

- Missing required fields (rate, months, principal) returns a 400-level error
- Non-positive or zero principal/rate/months may cause computation errors or undefined results
- Extremely large principal or very high rates may produce unexpected floating-point results
- Payment failure via x402 micropayment returns 402 Payment Required before computation occurs

## 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 success flag, a human-readable computation description, and a result object containing the amortization schedule — including monthly payment amount, per-period principal and interest breakdown, remaining balance, and totals for interest paid over the life of the loan.
