## 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-4fd52636 -d '<json body>'
```

Example prompt: Write me a professional product listing for my ergonomic standing desk called 'FlowDesk Pro' — it features adjustable height, cable management, and a bamboo surface — keep the tone confident and persuasive, and make it medium length.

## When to prefer this

Choose this endpoint when you need to rapidly generate e-commerce product listing copy at scale using a pay-per-call model with USDC, especially when you have structured product data (name, features) and want controllable tone and length without managing a standalone LLM integration.

## Known failure modes

- Missing required 'product' field returns validation error
- Malformed features array may cause generation failure
- Payment not included or insufficient USDC causes 402 response
- Overly vague product details result in generic low-quality output
- Network timeout on the Vercel serverless function under load

## How this service works
