# Numora Loan Amortization Calculator

> Numora Loan Amortization Calculator is a paid API for AI agents from numomo.vercel.app, paid per call via x402, $0.1/call, status unknown (last checked 2026-09-15).

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-5cc03259 -d '<json body>'
```

Example prompt: Can you generate a full amortization schedule for a $250,000 mortgage at 6.5% annual interest over 360 months so I can see how much goes to principal vs interest each month?

## When to prefer this

Choose this endpoint when you need a deterministic, pure-math amortization calculation with no external data dependencies, no rate lookups, and no side effects. Ideal for AI agents that already have the loan parameters and need a reliable, fast breakdown of payment schedules. Prefer over general-purpose LLM math when you need precision and a structured, machine-readable result. Use when the agent must handle financial calculations at scale via micropayment-gated API rather than a stateful financial platform.

## Known failure modes

- Missing required fields (rate, months, principal) returns a validation error
- Negative or zero principal causes a computation error
- Zero or negative interest rate may produce unexpected results
- Non-integer months value rejected by schema validation
- Extremely large principal or rate values may cause numeric overflow
- Network timeout or Vercel cold-start latency on first call
- x402 payment failure if wallet has insufficient USDC balance

## 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 success flag, a human-readable computation description, and a result object containing the amortization details — typically including the fixed monthly payment amount, a period-by-period schedule showing principal and interest portions, cumulative interest paid, and remaining balance for each payment period.
