## 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 write-product-listing-b15fa3f7 -d '<json body>'
```

Example prompt: Write me an SEO-optimized Amazon product listing for my wireless noise-canceling earbuds with 40-hour battery life — target keywords like 'wireless earbuds', 'noise canceling', 'long battery life', and include bullet points highlighting the key specs.

## When to prefer this

Choose this endpoint when you need ready-to-publish, marketplace-specific product listings with SEO optimization baked in. It is ideal for e-commerce sellers launching new products on Amazon, Shopify, or eBay who want keyword-targeted copy and bullet-point formatting without manual copywriting. Prefer it over generic text generation APIs when you specifically need marketplace-convention-aware formatting and SEO keyword integration in a single call.

## Known failure modes

- Missing required 'product' field returns a validation error
- More than 10 keywords provided may be truncated or rejected
- Unsupported marketplace value (not amazon/shopify/ebay) may cause incorrect formatting
- Vague or minimal product description yields generic, low-quality output
- Payment failure (x402) returns 402 status before generation begins
