## 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 gateway-d402-xyz-extract-normalized-product-data-via-d402-gateway-27e916e3 -d '<json body>'
```

Example prompt: Can you extract the product title, price, availability, and images from this product page: https://www.amazon.com/dp/B08N5WRWNW — I need normalized structured data including the seller name and rating if available.

## When to prefer this

Use this endpoint when you need to extract product data from any ecommerce site without knowing the specific retailer in advance. If you know the product is on Amazon, Shopify, Walmart, or Target specifically, prefer those provider-scoped endpoints for higher accuracy. Choose this general endpoint for unknown or mixed retailers, or when building a universal product data pipeline.

## Known failure modes

- URL is not a public product page — returns error status with message
- Page requires login or is geo-blocked — extraction fails with error
- Timeout exceeded (max 45000ms) — task returns error status
- Unsupported page structure — low confidence scores or null fields
- Invalid URL format — schema validation rejects the request
- Worker unavailable — task accepted but result delayed or errored
