## 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 stableproducts-channel3-image-search-367e26dc -d '<json body>'
```

Example prompt: Can you search for products that look like this headphone image (https://images.unsplash.com/photo-1505740420928-5e560c06d30e?w=500) — show me up to 10 new, in-stock items under $200 in the US in USD?

## When to prefer this

Choose this endpoint when you need to find real purchasable products that visually resemble a reference image, especially when you have rich filtering needs (price range, condition, availability, brand, country, currency). Prefer this over text-based product search when the user has a visual reference but lacks the exact product name. It is particularly useful for shopping assistants, gift finders, and fashion recommendation agents operating across multiple countries and currencies.

## Known failure modes

- Invalid or unreachable image URL returns an error or empty results
- Image format not supported may return no matches
- Filters too restrictive (e.g., rare brand + out-of-stock only) may return empty product list
- Unsupported country/currency/language combination returns validation error
- Exceeding limit maximum of 30 returns a schema validation error
- Payment failure (x402) results in 402 response before any data is returned

## How this service works

Product catalog APIs powered by x402.

## Output

Returns a list of visually similar products each with a product ID, title, brand(s), price and currency, compare-at price, availability status, and one or more merchant offer URLs with domain and commission rate. Includes a best_offer field pointing to the cheapest or most relevant purchase link. Supports pagination via page tokens.
