## 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-coleman-liau-index-calculator-549c036f -d '<json body>'
```

Example prompt: Can you calculate the Coleman-Liau readability index for this paragraph: 'Artificial intelligence is transforming how businesses operate, enabling automation of complex tasks that once required significant human effort and expertise.'

## When to prefer this

Use this endpoint when you need a character-count-based readability metric (Coleman-Liau) rather than syllable-based metrics like Flesch-Kincaid. It is particularly useful for digital text where syllable counting is unreliable, and when you need a quick grade-level estimate for content optimization or educational targeting.

## Known failure modes

- Empty or missing text input returns an error
- Text too short to compute meaningful statistics may return unreliable scores
- Non-UTF8 or malformed text encoding may cause processing failure
- Network timeout on large text payloads
- Payment failure via x402 protocol blocks the request
