## 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 sitecheck-shop-social-costco-canada-product-tracker-bb6a8840
```

Example prompt: Can you look up the current price, stock status, and rating for these Costco Canada products: 100107807 and 100234567?

## When to prefer this

Use this endpoint when you need structured product data (price, availability, rating, shipping) from Costco Canada (costco.ca) and have one or more specific product IDs. It is not a search tool — you must already know the product ID(s). Do not use for Costco US (costco.com), keyword search, or bulk scraping beyond 5 products per call.

## Known failure modes

- Product ID not found on costco.ca — found field returns false with no product details
- More than 5 IDs submitted — likely rejected or truncated
- costco.com (US) IDs will not resolve — only costco.ca (Canada) is supported
- Schema.org data missing or changed on a product page — partial or empty fields returned
- Network timeout or upstream costco.ca unavailability — HTTP error returned
- Invalid ID format (non-numeric or malformed URL) — may return error or empty result

## How this service works

Pay-per-call e-commerce, product, price and social media data tools for AI agents, from public sources. Payment: x402, USDC on Base, Solana, Arc, Polygon, Arbitrum, Monad, World Chain, Optimism, Avalanche, Celo or Stellar, or RLUSD/XRP on the XRP Ledger. No signup, no API key; a failed call is not charged.

## Output
