## 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-rakuten-ichiba-japan-product-search-3af9e027
```

Example prompt: Search Rakuten Ichiba Japan for 'matcha powder', sort by best review average, and give me the top 5 results with price in JPY, shop name, review score, and whether they ship overseas.

## When to prefer this

Choose this endpoint when you specifically need product data from Japan's Rakuten Ichiba marketplace — including JPY pricing, Rakuten points rate, Japanese shop names, and Rakuten-specific review metrics. Prefer it over generic product search APIs when the user wants Japanese domestic retail results, Rakuten-specific seller data, or is comparing products available on Rakuten. Not suitable for stock history, order placement, or non-Rakuten Japanese retailers.

## Known failure modes

- Missing required 'q' parameter returns a validation error
- Query keyword exceeds 60 characters causes an API rejection
- Sort value not in the allowed enum (standard, +itemPrice, -itemPrice, -reviewCount, -reviewAverage, -updateTimestamp) may cause an error or be ignored
- Limit value outside 1-30 range may be clamped or rejected
- No matching products returns an empty items array with count 0
- Rakuten API rate limits or downtime may cause upstream errors
- Non-HTTPS or malformed worker URL returns network error
