## 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 agent-product-validator-240b2757
```

Example prompt: Before my shopping agent tries to buy from this listing, can you check if the product page at https://example.com/product/widget-pro has enough reliable data — pricing, availability, and specs — for a commerce agent to work with?

## When to prefer this

Use this endpoint when an AI commerce agent needs to gate its actions on data quality — specifically before attempting to parse, compare, or purchase from a product page. Prefer this over generic web scrapers or content validators when you need a commerce-specific reliability score rather than raw extracted data. Pairs naturally with Agent Offer Comparator (to validate before comparing) and Agent Missing Field Checker (to confirm fields before checkout).

## Known failure modes

- URL is not publicly accessible or returns a non-200 HTTP status
- Page is behind a login wall or CAPTCHA, preventing data extraction
- Product page has no recognizable structured product data (not an e-commerce page)
- URL points to a non-product page such as a homepage or category listing
- Malformed or non-HTTP/HTTPS URL provided
- Page loads JavaScript-rendered content that cannot be crawled
- Payment of 0.02 USDC not completed, returning 402
