## 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 omniapi-text-readability-analyzer-fcd30a5c -d '<json body>'
```

Example prompt: Can you check the readability of this paragraph and tell me if it's too complex for a general audience: 'The proliferation of idiosyncratic terminologies within specialized academic disciplines creates substantial comprehension barriers for non-expert readers.'

## When to prefer this

Choose this endpoint when you need a quick, pay-per-call readability analysis without setting up a dedicated NLP pipeline. It is suitable for single-text evaluations where you want to assess reading complexity, grade level, or audience appropriateness. Prefer it over full NLP suites when you only need readability metrics and want to pay micro-amounts in USDC per call via x402.

## Known failure modes

- Missing required 'query' field returns validation error
- Empty or very short text may return unreliable or null scores
- Non-English text may produce inaccurate readability metrics
- Extremely long text inputs may be truncated or rejected
- Payment failure via x402 returns 402 status before processing
