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-b54885cc -d '<json body>'
```

Example prompt: Calculate the full amortization schedule for a $250,000 mortgage at a 6.5% annual interest rate over 360 months — I want to see the monthly payment and how much goes to principal vs interest.

## When to prefer this

Choose this endpoint when you need a pure mathematical computation of a loan amortization schedule with no external data dependencies — ideal for AI agents performing financial planning calculations, mortgage analysis, or consumer loan breakdowns where only the principal, rate, and term are known and no third-party data lookup is required.

## Known failure modes

- Missing required fields (rate, months, principal) returns a 400-level error
- Negative or zero principal or rate may return a computation error
- Non-integer months value is rejected by schema validation
- Rate provided as percentage vs decimal may produce unexpected results if not normalized
- Service unavailability or payment failure returns a 402 or 5xx error

## 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 result object containing the computed amortization data (monthly payment amount, per-period principal and interest breakdown, total interest paid, total cost), along with a human-readable computation description string and a success boolean.
