## 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-hapax-legomenon-counter-2357ca72 -d '<json body>'
```

Example prompt: Can you count how many hapax legomena — words that appear exactly once — are in this text: 'The quick brown fox jumps over the lazy dog and the dog barked back at the fox'?

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.002 per call) computation of hapax legomena — words appearing exactly once — in a text blob. It is suitable for lightweight corpus analysis, authorship profiling, or vocabulary diversity metrics where a single API call per text is sufficient. Prefer alternatives if you need full word-frequency distributions, part-of-speech tagging, or more sophisticated NLP pipelines.

## Known failure modes

- Missing or empty 'text' field in the request body — may return an error or zero count
- Extremely long text inputs may time out or be rejected
- Non-string values for the 'text' field may cause processing errors
- Ambiguous response schema means the exact format of hapax count vs list is unclear
- Network or payment authentication failures may prevent the endpoint from being reached
