## 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 compound-interest-calculator-9ea804d8
```

Example prompt: Can you calculate compound interest on a $10,000 principal at a 5% annual rate over 10 years, compounded monthly?

## When to prefer this

Use this endpoint when you need a fast, deterministic, server-side compound interest calculation and want a structured JSON response. Prefer it over building local math when you need reliable, consistent results with exact figures for principal, rate, duration, and compounding frequency.

## Known failure modes

- Missing required query parameter (principal, rate, years, or compoundsPerYear) returns an error
- Non-numeric or negative values for parameters may return a validation error
- Zero compoundsPerYear would cause a division-by-zero error
- Payment failure (x402 protocol) if USDC balance is insufficient

## How this service works

## Output

A deterministic JSON object containing the final amount (principal plus all accumulated interest) and the total interest earned over the specified period, given the exact input parameters.
