## 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-automated-readability-index-calculator-03cb23ff -d '<json body>'
```

Example prompt: Can you calculate the Automated Readability Index score for this paragraph: 'Artificial intelligence is transforming industries by automating complex tasks, improving efficiency, and enabling new forms of human-machine collaboration.'?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.002 per call) automated readability computation without setting up your own text analysis library. It is best suited for quick, single-text ARI scoring where you want a simple numeric readability estimate. Prefer this over general NLP APIs when you specifically need the ARI metric rather than Flesch-Kincaid, Gunning Fog, or other readability formulas.

## Known failure modes

- Empty or missing text field returns an error or null result
- Extremely short text (fewer than a few words or sentences) may produce unreliable or nonsensical ARI scores
- Very long texts may hit request size limits
- Non-English text may produce inaccurate readability scores since ARI is designed for English
- Malformed JSON request body returns a 400-level error
- Service unavailability returns a 5xx error
