## 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 kihustle-effective-interest-rate-calculator-17835bfb -d '<json body>'
```

Example prompt: What's the effective annual interest rate if the nominal rate is 6% compounded 12 times per year?

## When to prefer this

Use this endpoint when you need a quick, cheap ($0.002 USDC) serverless computation of effective annual interest rate from a nominal rate and compounding frequency, without building the formula locally. Suitable for financial comparison workflows, personal finance agents, and educational tools where a lightweight hosted computation is preferred over client-side math.

## Known failure modes

- Missing or non-numeric nominal_rate returns validation error
- Missing or non-integer periods_per_year returns validation error
- periods_per_year of zero or negative causes division-by-zero or invalid computation
- Extremely large periods_per_year values may return floating-point precision edge cases
- Service downtime returns non-200 HTTP response requiring x402 payment retry logic
