How this service works
Amazon offers & sellers API (US) by ASIN: the buy-box winner plus third-party sellers, each with seller name, price, regular price, discount, condition (new/used), ships-from and seller rating. Amazon offers and sellers for buy-box tracking and price comparison. No offers returns empty results.
Output
A list of seller offers for the given ASIN, each including the seller name, current price, regular (list) price, discount amount or percentage, product condition (new/used), ships-from location, and seller rating. The buy-box winner is identified. If no offers exist, an empty result set is returned.
Example use cases
Buy-box winner monitoring for repricing
“Check who's currently winning the buy box for ASIN B08N5WRWNW and tell me their price, seller name, and rating so I can decide whether to adjust my listing.”
Lowest price sourcing for shoppers
“Find me all the sellers offering ASIN B0HCXW6CDR right now — I want the cheapest available price across new and used conditions and where each seller ships from.”
Competitive seller landscape analysis
“Pull every third-party seller on Amazon for ASIN B07XJ8C8F5, including their prices, discounts off the regular price, and seller ratings, so I can map out the competitive landscape.”
Technical details
Endpoint
POSThttps://products.openverbs.com/v1/amazon-sellersWhen to prefer
Use this endpoint when you need real-time seller-level pricing data for a specific Amazon ASIN — especially for buy-box tracking, competitive repricing, price arbitrage, or presenting shoppers with the cheapest available offer. Prefer this over a product detail endpoint when seller identity, condition, rating, and per-seller pricing matter more than general product metadata.
Side effects
- Invalid ASIN format (not 10 alphanumeric uppercase characters) returns a validation error
- ASIN exists on Amazon but has no active offers — returns empty results
- ASIN not found on Amazon US marketplace returns empty or error
- Transient Amazon data unavailability may result in stale or missing offer data
- Payment failure (insufficient USDC balance) blocks the request via x402
