## 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 x402node-shopping-search-be4e0b75 -d '<json body>'
```

Example prompt: Search for 'wireless noise-cancelling headphones under $200' and show me the top shopping results with links.

## When to prefer this

Choose this endpoint when you need shopping-specific search results (product links, titles, snippets) for a keyword without setting up an account or API key. Ideal for AI agents that need pay-per-call access to product discovery via USDC micropayments on Base. Prefer over general web search endpoints when the goal is specifically finding purchasable products.

## Known failure modes

- Payment not received or insufficient USDC — request rejected with 402 status
- Empty or missing 'keyword' field — may return empty results or error
- Keyword too vague — results may be irrelevant or low quality
- Network timeout — no results returned
- Product query returns no matching shopping results — empty results array
