The Amazon offers API returns one row per seller offer on a listing, with the price, the shipping cost, the condition, an FBA flag and a true/false Buy Box column. It runs daily or on demand, and the rows reach your repricer or your own rules through the REST API or a CSV file.
On competitive ASINs, the Buy Box moves between sellers often. Seller reports show your own share, not which competitor won it, when or at what price.
Your repricer is fed by marketplace APIs built around your own listings. Detail on competing sellers is limited, and there is no history of who held the Buy Box.
Same SKU on Amazon, eBay, Walmart — each marketplace's pricing engine moves independently. Manual reconciliation is impossible at scale.
FBA inventory levels affect Buy Box win-rates. Without stock signal monitoring, you set prices on partial information.
Marketplaces flag restricted-brand violations weeks after they occur. Without seller-side monitoring, your account suspends without warning.

A repricer that chases the lowest number on the page will cut your margin against an offer that was never competing with you. This is the same ASIN read properly — B07ZL47PXP, where you sit at $45.99.
The ASIN page shows one price at the top and a stack of offers underneath. Four sellers are live: NorthTech at $43.49 FBA, you at $45.99 FBA, ValuePort at $41.20 FBM with six-day handling, and ReStock at $34.00 used. A single-price scrape returns $43.49 and loses the other three, including the one holding the Buy Box.
ValuePort is cheaper and irrelevant — six-day merchant fulfilment is not Buy Box eligible against Prime-speed offers, so it wins nothing. ReStock is used condition, a different product as far as the Buy Box is concerned. Repricing against either is a margin cut that buys no additional sales.
NorthTech at $43.49, FBA, new, in stock — that is the offer holding the Buy Box and the only number your rule should read. The row you receive carries the winner, their price, their fulfilment type and the timestamp, so the repricer decides on the same evidence you would have used by hand.
Sellers reprice against the lowest offer because it is the only field they have. Price is one input among several, and the others are readable from the listing — which is why a lower price frequently loses.
FBA and Prime-speed merchant fulfilment compete on one tier; slow merchant fulfilment competes on another. A cheaper offer with six-day handling is not in your race at all. Reading fulfilment type alongside price is what separates a real competitor from a number that only looks like one.
Used, renewed and open-box offers sit on a separate Buy Box from new. They regularly sit at the bottom of the offer stack and regularly get scraped as "the lowest price". A repricer fed that number cuts a new-condition price to chase a refurbished one.
An offer that has run out does not hold the Buy Box regardless of its price, and your own FBA stock position affects whether you can hold it. Stock signal read from the listing tells you when a competitor's price stopped mattering — often the cheapest explanation for a Buy Box you suddenly won or lost.
A single snapshot cannot tell you whether a competitor is testing a price for an afternoon or has repositioned permanently. Only the second is worth matching. Every run retained means a Buy Box loss can be traced to the offer and the hour it changed, rather than guessed at from a seller report a week later.
You supply the ASINs and the cadence. You receive the full offer stack per listing, with the Buy Box winner identified.

Delivered by REST API or CSV export. Offers from the same ASIN stay on separate rows, so you can see who you are actually losing the Buy Box to.
One row per offer per run, not one row per ASIN. This is B07ZL47PXP as it lands in your repricer.

Seller and price data from the listing itself, for the ASINs that matter.
One row per seller offer on an Amazon listing: seller name, price, shipping, condition and FBA flag.
Pull Buy Box and seller data through the REST API into your own pricing engine, or export CSV for your repricer rules.
A Buy Box tracker is a list of who holds the Buy Box on each of your ASINs, saved run by run. Here that is the Amazon offers API on a schedule. One call per listing costs €0.00015, so 200 ASINs checked daily are 6,000 calls a month, €0.90.
One row per seller offer: the seller name and ID, the item price, the shipping cost, the condition, whether Amazon fulfils it (FBA) and whether that offer holds the Buy Box. One call returns about 10 offers plus the total offer count for the listing.
Every run saves the offer rows in your Scrapewise account. They reach your repricer or your own pricing rules through the REST API or a CSV file. Scrapewise is the data feed: it changes no price itself.
Stop running marketplace pricing on marketplace API data alone. Scrapewise gives marketplace sellers independent Buy Box and seller data.
