## 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 automated-readability-index-calculator-2ba76e05 -d '<json body>'
```

Example prompt: Can you calculate the Automated Readability Index score for this paragraph: 'Artificial intelligence is transforming the way businesses operate, enabling automation of complex tasks and driving efficiencies across industries.'?

## When to prefer this

Choose this endpoint when you need a fast, cheap, single-call readability assessment using the established ARI formula. It is best suited for English-language content where you want a grade-level estimate without heavyweight NLP infrastructure. Prefer it over more complex readability suites when you only need the ARI metric specifically, and not Flesch-Kincaid, Gunning Fog, or SMOG simultaneously.

## Known failure modes

- Empty or missing text field returns an error or undefined result
- Extremely short text (one word or one character) may produce unreliable or nonsensical ARI scores
- Non-English text may yield inaccurate scores since ARI is calibrated for English
- Very long texts may hit payload limits or timeout
- Malformed JSON body returns a 400-level error

## Output

Returns a JSON object containing the computed readability result and a success status indicator. The ARI score is a numeric value corresponding to a US grade level (e.g., score of 8 ≈ 8th grade); higher scores indicate more complex text.
