## 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-score-api-0cf08c89 -d '<json body>'
```

Example prompt: Can you check the readability score of this blog intro: 'Artificial intelligence is rapidly transforming the way solo entrepreneurs build and scale digital income streams, enabling previously inaccessible automation workflows to become a core part of their daily operations.'?

## When to prefer this

Choose this endpoint when you need a quick, low-cost readability computation on a text string within an automated workflow, particularly if you are already working within the x402 micropayment ecosystem. At $0.001 USDC per call it is affordable for bulk content auditing pipelines. Note that the response schema is minimal and not fully documented, so prefer more established readability APIs (e.g. Readable.io, dedicated NLP services) if you need detailed metric breakdowns, grade-level explanations, or multi-metric scoring.

## Known failure modes

- Empty or missing 'text' field returns an error or undefined result
- Extremely long text may cause timeout or unexpected behavior
- Non-string input types may fail validation
- Response schema is minimal and may not include detailed error messages
- Ambiguous score format due to limited response documentation
