Amazon data, ready to use
Behind every third-party offer on Amazon stands a seller with a public profile page: a storefront name, a legal business name and address, a feedback rating and a catalogue of products. everydata.io exposes this data through three GET endpoints that work together. The seller lookup returns the profile for a sellerId, the seller-products endpoint pages through everything that seller lists, and the offer listing returns all sellers competing on a single ASIN – including who currently holds the buy box. Together they let you map the seller landscape of any marketplace from the outside.
GET /amz/amazon-lookup-seller returns sellerName, aboutSeller (the self-description), storefrontUrl, the feedback rating as rating, percentageRating and countRating, and sellerDetails – a key/value map of the profile page's detailed seller information exactly as Amazon labels it, such as "Business Name:" or the registered address. feedbackSummary holds the 30-day / 90-day / 12-month / lifetime table and feedback the most recent individual feedback entries with rating, text and rater.
GET /amz/amazon-seller-products returns the seller's listings as a search-style page: searchProductDetails with asin, productDescription, price, productRating, countReview, salesVolume and dpUrl, plus resultCount, numberOfProducts, currentPage, nextPage and lastPage for paging. GET /amz/amazon-lookup-prices closes the loop per product: every offer for an ASIN with sellerName, sellerId, price, shippingPrice, condition, fulfilledBy, prime and the seller's own rating.
- Seller profile: storefront name, about text, business name and registered details from the seller page
- Feedback rating, positive percentage, rating count and the 30/90/365-day feedback summary
- Recent feedback comments with star rating, text and rater
- Complete seller catalogue with paging – up to 4,000 listings on large storefronts
- Offer listing per ASIN with seller ID, price, shipping, condition, fulfilment and Prime flag
- Condition filter for offers: new, usedLikeNew, usedVeryGood, usedGood, usedAcceptable
- All marketplaces by domainCode; seller IDs are marketplace-specific
What teams build with this
Seller due diligence and brand protection
Resolve every seller found on your brand's ASINs to a business name and address, flag unknown resellers and document unauthorised offers with timestamped evidence.
Buy-box and competitor monitoring
Poll the offer listing for your key ASINs, record which sellerId holds the lowest landed price and how your own offer compares in price, shipping and fulfilment.
Lead generation for seller services
Agencies and software vendors page through a seller's catalogue to size the account – number of listings, rating levels, review counts – before reaching out.
Marketplace research
Map how many sellers compete in a category, how concentrated the buy box is and which fulfilment model (FBA vs merchant) dominates, marketplace by marketplace.
Example request and response
Start with a sellerId, the string after me= or seller= in a storefront URL (A2L77EE7U53NWQ is Amazon Resale on amazon.com). Both seller endpoints require sellerId and domainCode; seller-products adds page. To discover sellers you do not know yet, call /amz/amazon-lookup-prices for an ASIN – each offer carries the sellerId you can then feed into the profile lookup.

},
"feedbackSummary": {},
"feedback": [],
"sellerId": "A2L77EE7U53NWQ",
"domainCode": "com"
}Amazon's own storefronts (Amazon Resale, Amazon Warehouse) show no feedback section, which is why rating and countRating are 0 in the example; an independent seller returns values such as rating 4.8, percentageRating 96 and countRating 12,540 together with a populated feedbackSummary. Keys in sellerDetails follow the marketplace language – on amazon.de expect "Geschäftsname:" rather than "Business Name:".
For the catalogue, GET /amz/amazon-seller-products?sellerId=A2L77EE7U53NWQ&domainCode=com&page=1 returns 16 products per page with lastPage in the hundreds for big sellers; follow nextPage until it disappears. Prices in the catalogue view can be 0 when Amazon shows "See options" for a tile – look up the ASIN individually when you need the exact number.
The offer listing (GET /amz/amazon-lookup-prices?asin=B07ZPKN6YR&domainCode=com&condition=new) responds with currencyCode, currencyAbbreviation, currentPage, lastPage and an offers array. PRODUCT_NOT_FOUND_RESPONSE with "No offers found" is a normal answer for ASINs without a marketplace offer – for instance when Amazon is the only seller – not an error.

Each profile lookup, each catalogue page and each offer-listing page is one request. Profiling 200 sellers with their first catalogue page and checking offers on 1,000 ASINs daily comes to roughly 34,000 requests a month, which fits the Production plan (50,000 requests, €80). Overage is €3 per 1,000 requests on that plan; upstream failures are never billed.
