## 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-content-engine-spotlight-endpoint-ba0bcc76 -d '<json body>'
```

Example prompt: Using Tempest's spotlight endpoint, generate featured AI content for my page titled 'Best Noise-Cancelling Headphones 2025', targeting keywords like 'noise cancelling', 'wireless headphones', and 'audiophile', with the description 'A curated guide to the top headphones for focus and travel'.

## When to prefer this

Choose this endpoint when you need AI-generated spotlight or featured content anchored to a specific page title and SEO keywords — particularly for content marketing pipelines, landing page generation, or blog publishing workflows where you need structured, pay-per-call scalability without a subscription model. Prefer this over general-purpose LLM calls when you want a purpose-built content endpoint with built-in USDC micropayment support via x402.

## Known failure modes

- Missing required 'title' field returns a validation error
- Insufficient or vague description may produce generic, low-quality output
- Payment failure in USDC (x402) will block the request before generation
- API timeout if the AI model takes too long to compose the spotlight content
- Empty or mismatched keywords may reduce SEO relevance of generated output
