## How to call it through Zero

```sh
zero fetch --capability product-description-council-8547bfec -d '<json body>'
```

Example prompt: Use the Product Description Council to write 3 product listing variants for my wireless noise-cancelling headphones targeting Amazon — keywords are 'noise cancelling', '40-hour battery', 'foldable' — specs are Bluetooth 5.3, 40h battery, 250g, USB-C charging, and here's a competitor listing to beat: https://www.amazon.com/dp/B09XYZ.

## When to prefer this

Choose this endpoint when you need high-quality product listing copy that benefits from multi-model diversity — e.g. when a single model's output feels flat or generic, when you want marketplace-specific optimization, or when you need to incorporate competitor intelligence and target keywords into a humanized final description. It's especially strong for Amazon, Etsy, Shopify, and eBay listings where conversion copy matters.

## Known failure modes

- Missing or too-vague brief resulting in generic output
- Competitor URL inaccessible or blocked, causing that context to be ignored
- Exceeding num_outputs maximum of 10 returns a validation error
- Payment failure or insufficient USDC balance preventing the call
- Overly long context object may be truncated by underlying model context limits

## How this service works

Product Description Council: 3 frontier models write product listings independently. Grok-4 picks the best elements. Claude Sonnet humanizes. $7.00/call. Pass context like: product, marketplace, keywords, specs, competitor_url, etc.

## Output

Returns one or more synthesized product descriptions where multiple frontier models each drafted independent versions, Grok-4 selected the best elements from each, and Claude Sonnet humanized the final output — yielding polished, marketplace-ready listing copy.
