    22 Markets · Buy Box & Seller Data

    What You Get

    Every Marketplace. Every Signal. No Seller Account

    Coverage

    Every Amazon marketplace

    Amazon.com, .de, .co.uk, .co.jp and 18 more sit behind the same request shape. Marketplace, currency and language resolved server-side.

    Depth

    Buy Box, not just price

    Buy Box owner, FBA vs FBM, complete offer list, seller count, BSR and category rank, the fields your repricer actually branches on.

    Access

    No SP-API required

    kwery reads the public product page, so you don't need a seller account or SP-API credentials to track competitor ASINs.

    How It Works

    Every ASIN, resolved to one Buy Box truth

    Send an ASIN, GTIN, EAN or UPC. kwery resolves it in the target marketplace, fetches the live product page, and returns the current Buy Box state plus the full offer stack, proxies, sessions and anti-bot fully abstracted.

    1. Send an ASIN or GTIN

      Address ASINs directly or resolve GTIN, EAN and UPC to the correct ASIN per marketplace, no pre-matching table on your side.

    2. Resolve and fetch live

      kwery handles proxy rotation, session affinity and CAPTCHA solving for you; you never see 503s or bot challenges in your responses.

    3. Buy Box + offer stack

      Every response returns the current Buy Box owner, seller type, full offer stack and demand signals, one shape across all 22 marketplaces.

    Browse all FAQs

    kwery is an Amazon price tracking API for retail and repricing teams. Submit a list of ASINs or GTINs and get Buy Box ownership, seller count, stock status, and pricing back, resolved live across 22 Amazon marketplaces. Use it to feed a repricer, trigger alerts, or land data in your warehouse. One schema, resolved live. No dashboard to maintain.

    All 22 supported Amazon marketplaces: US, CA, MX, BR, UK, DE, AT, CH, ES, FR, IT, JP, IN, AE, AU, NL, SE, PL, BE, SG, TR and IE. The endpoint shape is identical across them; only the `country` parameter changes.

    Yes. kwery resolves GTIN, EAN, UPC and MPN codes to the matching ASIN in the target marketplace. You don't need to maintain a code-to-ASIN mapping table on your side.

    No. kwery reads the public product page a shopper sees, which is precisely what SP-API doesn't give you access to for competitor listings. You get competitor visibility without registering as a seller.

    Every response includes a `buybox` object with `price`, `seller_name` and `seller_id`, alongside `seller_type` (FBA / FBM / standalone-shop). The `offers` array carries every eligible third-party offer so you can score the runner-up. For what actually determines who wins it, see Amazon Buy Box, explained.

    Proxy pools, session rotation, browser fingerprinting and CAPTCHA solving are all handled server-side. If a fetch fails to return a valid page, the request doesn't count against your quota.

    Every result is resolved live from the marketplace at the moment of your request. You control exactly how fresh you need it with the `max_age` parameter, set it to 0 for a guaranteed live fetch every time.

    Yes. Subscribe an ASIN to monitoring and kwery will POST a signed payload to your callback URL when Buy Box, price or availability changes, so you only spend compute on real moves.

    Live only, every result reflects the current price and Buy Box state at the moment of your request. kwery doesn't store or return historical price trends; pair it with your own storage if you need to build a price-history view over time.
