Twelve sources today: Amazon, Google Shopping, ebay, Idealo, Kaufland, Otto, billiger.de, guenstiger.de, Walmart, Lidl, AliExpress, and Rakuten. Each one has its own page in the Source Library with the identifiers it accepts and the countries it covers. View Source Library.
Coverage spans North America, the UK, the DACH region, and the broader EU, with selected APAC marketplaces. Per-source regional availability is listed on each source page in the Source Library.
Yes. New sources are added based on customer demand and technical feasibility. Share the marketplace, region, and use case and the team will scope what is involved. Request a source.
kwery normalizes pricing, availability, seller, and listing identifiers across sources so the schema your application consumes stays consistent regardless of marketplace. Architecture and data model.
When a source updates its site, schema, or listing behavior, kwery absorbs the change centrally and keeps your integration stable. Your pipeline keeps receiving normalized results in the same schema, no code changes on your side. Brief gaps are surfaced as explicit health signals, never as stale data.
Yes. You specify which sources a job should cover, and results come back per source in the same response schema, so comparing an Amazon observation with an Idealo one needs no source-specific handling.
The core fields are identical everywhere: product, price, shipping, currency, condition, availability, seller, observed_at and confidence. Where a marketplace exposes something extra, it appears as a source-specific extension alongside the common fields rather than changing them. Architecture and data model.
Each marketplace-country combination is queried independently, so Amazon DE and Amazon US are separate sources rather than one blended result. Every record carries its own currency and locale, so you never have to infer which market an observation came from.
Yes. Each source has its own credit weight reflecting how expensive that marketplace is to resolve: most sources cost 1 credit per result, Amazon, Walmart and ebay cost 0.5, and Kaufland costs 3. The per-source rates are listed on the pricing page and in your dashboard, and every job reports what it consumed. View Pricing.
No. Access is granted per source-and-country pair, and each market is queried on its own. Amazon spans 22 marketplaces and Lidl 31 country markets, so covering several of them means several requests. The response schema stays identical across all of them.
No. Lidl is a first-party retailer, so its results carry Lidl's own price rather than a multi-seller offer list. Marketplaces such as Amazon, ebay and Kaufland return competing offers with seller identity attached, and comparison sites such as Idealo, billiger.de and guenstiger.de return merchant listings.
