kwery normalizes every marketplace into a consistent result shape, while preserving the fields that are specific to each one. This section documents what you get per source.

Amazon, Google Shopping, eBay, and Idealo are crawled natively. Kaufland, Otto, Billiger, and Guenstiger are also crawled directly. Walmart, Lidl, AliExpress, and Rakuten are covered through kwery's partner data feeds and normalized into the same result shape as every other source — you use them exactly the same way.
Rolling out. The four partner-feed sources — Walmart, Lidl, AliExpress, and Rakuten — are onboarding now and are not yet enabled by default on new accounts. Contact us to be enabled as they go live. The eight crawled sources are live today.
Access is granted per source.country pair — see Authentication.
Each source page lists the fields in the content object of a product result. Common, cross-source fields include:
| Field | Description |
|---|---|
name | Product title. |
url | Canonical product URL on the marketplace. |
currency | ISO currency of the prices. |
price_min / price_avg / price_max | Aggregates across the gathered offers. |
offers_count | Number of seller offers gathered. |
offers | Array of seller offers (see each source for fields). |
review_rating / review_count | Aggregate review signal, where available. |
Seller offers in offers[] typically include the seller/shop name, price, currency, shipping, and condition. Idealo carries the richest offer detail; see its page.
For some sources, seller/shop names are not always present on the first page load. kwery can resolve missing seller names for you — when this option is enabled on your account, the service performs the extra lookups needed to populate shop_name (and marketplace fields) on offers, and reports how many resolutions ran in the result counters. This is an account-level option; contact us to enable it for your plan.
Sources are enabled per account. Contact us if you need access to one that isn't yet active on your account — we'll confirm coverage and the available keys for your use case.
