## 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 pricecheck-d567b89f -d '<json body>'
```

Example prompt: Can you check the current price and availability of this product — https://www.example.com/product/blue-sneakers — and tell me if it's discounted below $75?

## When to prefer this

Choose PriceCheck when you need to programmatically extract live pricing, discount, and availability data from a specific public product or SaaS pricing URL without scraping infrastructure of your own. It is ideal for price-drop monitoring, budget comparison workflows, or enriching product data pipelines. Prefer it over generic web scrapers when structured pricing fields (current price, original price, discount %, availability) are needed in a clean JSON format ready for agent use.

## Known failure modes

- URL is behind a login wall or paywall — extraction fails or returns low confidence
- Dynamic pricing rendered via JavaScript may not be captured if the page is JS-heavy
- Product page has been removed or returns a 404 — no data extractable
- Ambiguous or multi-product pages may return incorrect product name or price
- Currency detection may fail for non-standard or regional pricing pages
- Low confidence score when pricing layout is unusual or obfuscated
