## 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 sitecheck-headline-generator-5ed8ddc2 -d '<json body>'
```

Example prompt: Generate 5 news-style headlines for this article about the city's new bike lane opening downtown — here's the text: 'The city unveiled a new protected bike lane on Main Street today, spanning 2 miles and connecting the downtown core to the waterfront park.'

## When to prefer this

Choose this endpoint when you need multiple distinct headline variations for a single piece of content or topic, especially when you want style-specific output (news, SEO, social, or email). It is ideal for content teams running A/B tests, marketers drafting campaign copy, or agents automating content pipelines where character counts matter. Prefer it over generic LLM completions when you need structured, consistently formatted headline output with character-length metadata per headline.

## Known failure modes

- Text exceeds 10,000 character limit — request rejected
- Count outside 1-10 range — validation error returned
- Neither text nor topic provided — missing required field error
- Invalid style enum value — error or fallback to default 'news' style
- Payment not received or insufficient USDC — 402 Payment Required response

## How this service works

Up to 10 headlines for a text or topic in one style: news, seo (under 60 characters, enforced in code), social or email subject. Each headline comes with its character count. Model output: check claims before publishing. Input text max 10,000 characters.

## Output

Returns a JSON object containing the requested style label, the number of headlines dropped (if any), a timestamp, and an array of headline objects each with the headline text and its character count.
