## 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-ca7868a4 -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) programmatic conversion from a nominal interest rate to its effective annual rate, especially in financial agent workflows where compounding period normalization is needed for comparison or reporting. Prefer this over manual formula application when integrating into automated pipelines.

## Known failure modes

- Missing or invalid nominal_rate field — returns error or unexpected result
- periods_per_year set to zero causing division-by-zero error
- Non-numeric inputs for rate or periods causing parsing failure
- Negative nominal rate may produce mathematically undefined or unexpected results
- API returns generic {result, status} response with limited error detail making debugging difficult
