## 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-42f68fe1 -d '<json body>'
```

Example prompt: Write a professional, medium-length product listing for my wireless noise-cancelling headphones called 'AuraBeats Pro' — key features include 40-hour battery life, active noise cancellation, and foldable design.

## When to prefer this

Choose this endpoint when you need to quickly generate structured product listing copy from a product name and feature list, especially when tone and length customization matters. It is ideal for e-commerce agents building or populating product catalogs at scale without a dedicated copywriting workflow. Prefer it over generic LLM completions when you want a pay-per-call model without managing API keys for a full AI provider.

## Known failure modes

- Missing required 'product' field returns a validation error
- Vague or very short product descriptions may produce generic or low-quality output
- Payment failure via x402/USDC results in 402 Payment Required before content is returned
- Ambiguous tone or length values may be ignored or defaulted
- Rate limits or server overload may cause timeouts on the Vercel deployment
