## 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-keyword-density-analyzer-bb9c1c0e -d '<json body>'
```

Example prompt: What's the keyword density of the word 'automation' in this paragraph: 'Automation is reshaping every industry. Automation tools save time and money. Many businesses now rely on automation for daily tasks.'?

## When to prefer this

Choose this endpoint when you need a lightweight, pay-per-call keyword density calculation without setting up a local NLP pipeline. It is best suited for single-text, single-keyword frequency analysis in the context of SEO content review, spam detection, or content optimization workflows. It is not ideal for bulk multi-keyword analysis across large corpora.

## Known failure modes

- Missing 'text' or 'keyword' field in request body — likely returns an error or unexpected result
- Empty text string causing division-by-zero or null density
- Very large text inputs may time out or be truncated
- Keyword not found in text — may return zero density or ambiguous result
- Non-string input types causing parsing failures
