## 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-product-listing-generator-fefde87a -d '<json body>'
```

Example prompt: Write a product listing for my new wireless noise-cancelling headphones — key features are 30-hour battery life, foldable design, and USB-C charging — use a professional tone and keep it medium length.

## When to prefer this

Choose this endpoint when you need to generate ecommerce or marketplace product listing copy at scale, especially when you want control over tone and length and are paying per-call via USDC. It is well-suited for agents automating product catalog content creation without maintaining a dedicated LLM prompt pipeline.

## Known failure modes

- Missing required 'product' field returns a validation error
- Overly vague product details may produce generic or low-quality output
- Network timeout or Vercel cold-start latency on first call
- Payment failure (insufficient USDC balance) blocks the request
- Unsupported or unusual tone strings may be interpreted loosely or ignored
