## 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 tempest-ai-article-generator-aef1b02e -d '<json body>'
```

Example prompt: Write a 1200-word article about the future of renewable energy in a professional tone, targeting keywords like 'solar power', 'clean energy', and 'sustainability'.

## When to prefer this

Choose this endpoint when you need to programmatically generate full-length, SEO-oriented articles at scale without a human writer — especially when you want keyword targeting baked in and need pay-per-call pricing rather than a monthly subscription. It's a strong fit for content pipelines, blog automation, and marketing copy generation.

## Known failure modes

- Missing required 'topic' field returns a 400 validation error
- Payment not included or invalid USDC amount causes a 402 payment required response
- Topic too vague or empty string may produce low-quality or off-topic output
- Extremely large word counts may time out or result in truncated content
- Unsupported style values may be ignored or cause unexpected formatting

## How this service works

## Output

Returns a JSON object with a success boolean and a data object containing the generated article content — typically the full article text structured as an AI-composed response matching the requested topic, style, keyword targets, and word count.
