# Numora Loan Amortization Calculator

> Numora Loan Amortization Calculator is a paid API for AI agents from numormo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-14).

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

## Facts

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-405897e5 -d '<json body>'
```

Example prompt: Calculate the full loan amortization schedule for a $250,000 mortgage at 6.5% annual interest rate over 360 months so I can see the monthly payment and principal vs interest breakdown.

## When to prefer this

Use this endpoint when you need a precise, server-side amortization calculation without implementing the math yourself. Prefer it over generic calculator tools when you need structured JSON output for downstream agent workflows, when you need a full per-period schedule rather than just the monthly payment, and when zero external data dependencies and deterministic results are required. Ideal for any AI agent handling financial planning, mortgage analysis, or loan comparison tasks.

## Known failure modes

- Missing required fields (rate, months, or principal) returns a validation error
- Negative or zero principal results in a computation error
- Zero or negative interest rate may produce unexpected results or an error
- Non-integer months value returns a schema validation error
- Extremely large principal or rate values may cause numerical overflow issues

## 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 description of what was computed, and a result object containing the full amortization schedule — including the fixed monthly payment amount, a per-period breakdown of principal and interest portions, and cumulative totals.
