## 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-readability-grade-api-9f68c9b0 -d '<json body>'
```

Example prompt: Can you check the readability grade of this paragraph: 'Artificial intelligence is transforming how we work, enabling solo entrepreneurs to automate repetitive tasks and focus on high-value activities that grow their income.'?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002 per call) programmatic readability grade for a piece of text, especially in content pipelines, publishing workflows, or quality gates where you want to ensure writing complexity is appropriate for your target audience. It is well-suited for single text snippets rather than bulk document analysis.

## Known failure modes

- Empty or missing 'text' field returns an error or undefined result
- Extremely short text may produce unreliable or meaningless readability scores
- Non-Latin or mixed-language text may not be supported and could return unexpected results
- Request timeout for very long text inputs
- Payment failure (402) if USDC balance is insufficient
