The Featured Offer seller on every ASIN, the marketplace resellers behind the price, and the retailers that carry you, read on schedule. Sellers below MAP surface automatically, with the listing as evidence.
Unauthorized seller monitoring software identifies third-party sellers offering your products without authorization, then adds the price, stock and Buy Box status behind each offer. On Amazon the sellers worth finding are rarely counterfeiters. They are grey-market resellers and product diverted from your own distribution, listing genuine goods below MAP and winning the Featured Offer from your authorized retailers.
Lightfeed is the monitoring half of brand protection: who held the Featured Offer on each ASIN, whether they are on your authorized list, at what price, with the listing as evidence. Takedowns, test buys and notices stay with your team, Brand Registry and counsel.
It handles counterfeits, hijacked listings and content. A reseller who bought through a distributor and lists below MAP is not infringing anything Amazon will act on. They win the Featured Offer, and your authorized retailers lose the sale and call you.
Circana and NielsenIQ tell you the category moved units on Amazon. They cannot tell you that a storefront created last month sold them 18% below MAP, or that it was the Featured Offer for nine days.
Storefront names change, offers appear for a weekend, repricers push every seller down behind the one who broke first. Checking ASINs by hand catches the ones that stay.
A product list with identifiers and MAP, plus the sellers and retailers that are allowed to carry you. CSV or API.
Featured Offer price and seller, Amazon or marketplace seller, coupon, stock, on Amazon.ca and Amazon.com. Daily is typical; hourly during launches and promotions.
Walmart, Target, Best Buy, mass, pharmacy and beauty banners, store by store where they publish it, so the Amazon price sits next to the shelf price your retail partners are defending.
Seller, price, gap to MAP, first seen, duration, the listing as proof. A marketplace-sellers-only view, and an export your brand protection team or distributor can act on.
| View | What it answers |
|---|---|
| Sellers by ASIN | Who held the Featured Offer on each run, Amazon or marketplace, authorized or not, at what price, and how long they held it. |
| MAP compliance | Every read below MAP by seller and retailer, with the tolerance you set, the gap, first seen and duration, and the listing as evidence. Marketplace-sellers-only filter for the distributor conversation. |
| Retail shelf next to Amazon | Price, promotion and stock at the retailers that carry you, store by store where published, so you can show a retail partner exactly what they were competing against and when. |
| What changed | New seller, seller lost the Featured Offer, price down, coupon added, out of stock, since the last run. |
| Competitor brands | The same reads for the competitor ASINs and SKUs you name, so a MAP break on your line is seen against what the category did that week. |
| Delivery | The web app, CSV exports, a JSON API, and an MCP server for Claude or your own agents. Enterprise adds Snowflake, BigQuery and Power BI delivery. |
A demo on public catalogs. Amazon was one of the twelve stores; the point is that the same product file produced the marketplace read and the retail shelf read together.
Every listing across Amazon, Sephora, Ulta, Macy's, Target, CVS, Walmart and Walgreens, 283 matched like for like.
“Listing B is a promotional bundle that includes a serum sample alongside the 1.7 oz cream.” Bundles, multipacks and refills never show up as false MAP violations.
Out of 897 decisions. The reviewer saw the images and the evidence, decided once, and the decisions hold for every future run.
Syndicated panels such as Circana and NielsenIQ, Amazon-only monitors, and enforcement suites such as TrackStreet and Wayvia (PriceSpider) each cover part of the problem.
| Syndicated panels | Amazon-only MAP tools | Enforcement suites | Lightfeed | |
|---|---|---|---|---|
| Seller named per ASIN | No | Yes | Yes | Yes, on every read, with authorized status |
| Retailers beyond Amazon | Sales only | No | Yes, .com prices | Yes, store by store where published |
| Competitor brands | Sales and share | Rarely | Usually your SKUs only | Whole categories next to yours |
| Evidence | Aggregated | Screenshots | Screenshots, case files | The listing, price, seller and timestamp on every read |
| Enforcement letters | No | Some | Yes, often managed | No. You keep the letters; we give you the evidence and the export |
| Price | Six figures a year | Per ASIN group, from about $100 a month | Custom, often $1,000+ a month | $699 a month for 100,000 products |
