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-a571305b -d '<json body>'
```

Example prompt: Write me a 1200-word long-form article on the future of renewable energy in a conversational journalistic style, using Inkbox.

## When to prefer this

Choose this endpoint when you need AI-generated long-form written content (articles, essays, blog posts) on a specific topic and can specify style and length. Prefer this over short-form or summarization endpoints when the output needs to be a full-length piece. Ideal for content pipelines, blog automation, or marketing teams needing scalable article generation with pay-per-call pricing.

## Known failure modes

- Missing required 'topic' field returns validation error
- Unsupported style value may produce unexpected tone or format
- Very high word_count values may result in truncated or degraded output
- Payment failure via x402/USDC returns 402 Payment Required before content is generated
- Network or generation timeout for very long pieces
