Know who wins the
Amazon Buy Box
The Buy Box changes by the second — and so does your revenue. We monitor it hourly across every ASIN you care about, flag the moment you lose it, and tell you exactly who took it and at what price.
Lose the Buy Box, lose the sale.
Around 83% of Amazon purchases go through the Buy Box. A product that loses it — even for a few hours — stops selling. Algorithmic sellers, unauthorised resellers, and price swings mean this can happen overnight.
Checking it by hand across hundreds of ASINs isn't a plan. You need a system that watches constantly and tells you the moment something changes.

A pipeline built for
Buy Box velocity
1. You send ASINs
Drop in a list — 50 SKUs or 50,000. We support any Amazon marketplace: US, UK, IN, DE, CA, JP, and more.
2. We watch hourly
Our infrastructure polls the Buy Box at a cadence you control — hourly, 15-minute, or event-driven.
3. You get alerted
Slack, email, webhook — the instant an ASIN changes hands, you know about it, along with the new winner and price.
4. History builds up
Every change is logged. Answer questions like "who's been winning on this ASIN for the last 60 days?" — backed by real data.
5. Feeds into your stack
JSON/CSV, REST API, S3, Snowflake, BigQuery, your BI tool — delivered in the format you already use.
6. We handle the hard part
Anti-bot handling, retries, CAPTCHAs, proxy rotation — you get a clean feed, not a broken scraper to babysit.
