## 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 openweb-ninja-realtime-costco-product-search-acc1dda7
```

Example prompt: Search Costco right now for 'Kirkland Signature olive oil' and show me the current prices and product details.

## When to prefer this

Use this endpoint when you need real-time, up-to-date Costco product data without scraping yourself — ideal for price comparison tools, deal finders, procurement agents, or any workflow that needs live Costco catalog data. Prefer this over general SERP APIs when you specifically need structured Costco product results rather than web search snippets. No API key setup required; just pay $0.003 USDC per call via x402.

## Known failure modes

- Empty results if the search term matches no Costco products
- Payment failure if USDC balance or x402 wallet is insufficient
- Rate-limited or blocked response if Costco's site is temporarily inaccessible
- Stale or partial data if Costco's website structure changes
- Malformed query returns 400-level error
