## 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 inkbox-ai-content-studio-longform-content-generator-e13b9b65 -d '<json body>'
```

Example prompt: Write me a 1200-word long-form article about the future of renewable energy in a journalistic style.

## When to prefer this

Choose this endpoint when you need to generate substantial, multi-paragraph written content on a specific topic with control over style and approximate length. Ideal for blog posts, articles, explainers, and editorial content. Prefer this over short-form endpoints when the user needs 500+ words of cohesive prose.

## Known failure modes

- Missing required 'topic' field returns a 400 validation error
- Payment not included or insufficient USDC balance triggers a 402 Payment Required response
- Extremely long word counts may result in truncated or incomplete output
- Vague or ambiguous topic input may produce generic or off-target content
- Service unavailability on the Netlify-hosted endpoint returns a 503 error
