    12 Marketplaces · Live Buy Box & Price Data

    Data Flow

    From a Market Move to Your Next Price Update

    Catch your competitors price moves, and let your own pricing logic decide what to do about it.

    Submit a list of GTINs or ASINs and kwery resolves each one live across Amazon, Google Shopping, eBay, Idealo and more, competitor price, Buy Box ownership, stock status, and seller data, in one schema regardless of marketplace. Structured results land wherever you need them: straight into your repricing engine, an alerting system, or your warehouse, refreshed on your schedule. No dashboard to maintain, and nothing to parse, just the data your pricing logic runs on.

    01 / Platform Builders

    Repricing platforms & tools

    Building a repricing product for other retailers? kwery is the data layer underneath your engine, competitor price, Buy Box, and stock, resolved live across every marketplace you support, so your product can focus on strategy and UX instead of scraping infrastructure.

    02 / In-House Teams

    Retailers running their own pricing logic

    Already have rules, a model, or a pricing team making the calls? kwery feeds your existing logic with the live signal it needs, no need to adopt a black-box repricer or hand your strategy over to a third party.

    Why Trust the Data

    Fast Enough to Act On. Trustworthy Enough to Automate.

    Two things worth knowing before any engine reprices off a number it didn't verify itself.

    Speed

    Real-Time Delivery. Instant Reaction.

    Each SKU streams to your webhook the moment it resolves, not after the batch finishes. The data lands, and you can reprice on it immediately.

    Freshness

    Freshness on Your Terms

    Set max_age to define how old a result can be before we re-fetch it, or use 0 to force a fresh crawl on every request.

    Recovery

    Never Miss a Result

    If your endpoint is briefly unavailable, deliveries retry automatically for roughly 45 minutes, then queue for replay, a short outage on your side never means a lost price change.

    Data Quality

    Confidence & Outliers

    Use result-level confidence and offer-level outlier flags to decide what your pricing logic can automate.

    ≥ 0.8

    High confidence

    Ingest and reprice directly

    0.5 – 0.8

    Usable with caveats

    Ingest; spot-check before acting on high-value SKUs

    < 0.5

    Low confidence

    Hold for review before repricing off it

    How It Works

    One Endpoint Behind Your Repricing Engine

    kwery wraps every marketplace behind one REST interface. You send a request, we handle proxy rotation, anti-bot, parsing, and validation. What comes back is clean, validated JSON, ready for your pricing logic, not another dashboard to babysit.

    1. Send a request

      GTINs or ASINs across Amazon, Google Shopping, eBay, Idealo, Walmart and more.

    2. Fetch & validate

      Buy Box owner, seller count, stock status and price, resolved live. Billed per successful request.

    3. Deliver

      Structured JSON straight into your repricing engine or warehouse.

    Coverage

    One API. Every Marketplace You Reprice Against

    One normalized signal across the marketplaces your repricing engine watches, live competitor prices, Buy Box ownership, seller data, and stock status, delivered in the same request shape every time.

    Repricing Signals

    How Repricing Signals Differ by Marketplace

    “Repricing” means something different depending on the source, some marketplaces merge competing offers into one shared listing with a single winner, others rank independent listings, and one benchmark source has no competing sellers at all. What you react to changes accordingly. Amazon is not listed below because its Buy Box mechanic has its own dedicated page.

    eBay's fixed-price competition works differently from Amazon's, multiple sellers can list the same item at Buy It Now prices, and eBay's Best Match ranking weighs price, seller performance, and listing quality together rather than exposing one merged winner slot. Completed-sale data adds a real-clearing-price signal that most other sources do not expose.

    Idealo ranks merchant offers by total landed price, item price plus shipping, not list price alone. Two merchants at the same headline price can rank differently because of delivery cost, so a repricing engine reacting only to listed price can misread its actual rank position.

    Walmart's Featured Offer weighs price heavily, while fulfillment method also matters significantly. Walmart Fulfillment Services and seller-fulfilled offers can perform differently at the same price point, so Walmart repricing needs to account for fulfillment rather than reuse Amazon logic unchanged.

    Otto's Buybox is influenced by price, shipping cost, delivery time, and seller trust. Otto itself can also appear as a competing offer alongside third-party sellers on the same listing, so the relevant repricing signal extends beyond the lowest observed price.

    Kaufland merges identical listings into a shared Buy Box across Germany, Poland, Czechia, Slovakia, and Austria. A repricing engine needs to read competition independently in each market rather than assume that one price position transfers unchanged across all five.

    billiger.de is a price-comparison aggregator rather than a shared-listing marketplace. Each merchant keeps a separate offer, ranked primarily by price, while the cost-per-click model shapes how aggressively merchants compete for visible positions.

    guenstiger.de does not offer paid placement: merchant ranking is decided by price, so the lowest-priced shop ranks first. Repricing against this source therefore has a cleaner price-position signal than marketplaces where fulfillment, seller standing, or advertising also influence placement.

    Lidl is not an open marketplace and has no competing sellers to react to. Here, repricing means using Lidl's direct retail price as an external discount benchmark for your own pricing decisions, not responding to a Buy Box or marketplace ranking position.

    AliExpress does not merge competing offers into one shared Buy Box. Each seller keeps a separate listing, and shoppers compare similar items across those parallel listings. Repricing here means staying competitive against that listing set rather than trying to win one shared slot.

    Rakuten Ichiba operates as a digital shopping mall where every seller has an independently branded storefront. Repricing means comparing against other storefronts selling similar products, while accounting for points-adjusted value rather than competing for a Buy-Box-style position.

    Google Shopping compares merchant offers side by side across regional markets rather than assigning one marketplace Buy Box. Staying competitive means reading the price shoppers see alongside Shopping Ads bidding and feed quality, since visibility is not determined by price alone.

    No, kwery delivers the data (competitor price, Buy Box, stock); your own repricing logic or tool decides and executes the price change. Think of it as the data layer underneath your repricing strategy, not a replacement for it.

    Yes, kwery is tool-agnostic. Point your existing repricer's data ingestion at our API, or feed it into a custom rules engine or model. There's no requirement to use any particular repricing tool.

    Every Amazon response includes a buybox object with price, seller_name and seller_id, compare buybox.seller_id against your own seller ID to detect a loss programmatically, or subscribe to change detection so we push a signed webhook the moment it changes.

    Yes, every response includes stock and availability alongside price, wherever the source itself exposes them, so your logic can raise price when a competitor is out of stock, not just react to price moves.

    Set max_age as low as needed, down to 0 for a guaranteed live fetch on every request, or subscribe to change-detection webhooks so you're notified (and only billed) when something actually moves, rather than polling.

    Yes, every response includes seller identity and observed price, so your own policy system can evaluate those fields in a separate monitoring workflow rather than your repricing logic.
