Price, rank, Buy Box and review sentiment on every ASIN you care about — as data, every day.
Amazon publishes an enormous amount on every product page: price, Best Sellers Rank, Buy Box winner, seller count, review distribution, A+ content and variation structure. Individually these are a page; captured across a category every day, they are the closest thing to a live feed of what is actually selling.
Product research, repricing and brand protection are all the same data problem wearing different hats. A reseller wants to know which ASINs in a category have demand and thin competition. A brand wants to know who is on their listings and whether they are holding the Buy Box. A private-label seller wants review text at volume because that is where the next product's feature list is hiding.
Amazon is among the most defended sites on the open web: fingerprinting, CAPTCHA challenges, aggressive rate limits, geo and session personalisation, and page structures that differ by category and by which experiment bucket you land in. The build uses a properly driven browser engine with consistent fingerprints, residential exits matched to the target marketplace, deliberate pacing, and per-category parsers rather than one selector set that silently returns empty on half the catalogue.
Excel, CSV, JSON, a Google Sheet that refreshes on a schedule, a direct write into MySQL or Postgres, or a REST endpoint your own tools can query.
Yes — full review text, rating, date and verified-purchase status, across as many ASINs as you need. Running the text through sentiment and topic analysis afterwards is a common add-on, and is usually where the actual insight comes from rather than the raw text.
It is the data layer under one. BSR, price, offer count, review velocity and category position across a whole category is exactly what the paid research tools are selling you — the difference is you get the raw data, on your criteria, and you own it.
It does, and it is genuinely the hardest site in this list. What makes it work is a real browser engine with consistent fingerprinting, residential exits, honest pacing and per-category parsers. It is slower than a naive scraper, and unlike a naive scraper it is still returning data next month.
Any of them — US, UK, DE, FR, IT, ES, CA, JP and the rest. Multi-marketplace runs match on ASIN so the same product lines up across countries in one row, which is what makes cross-border price comparison possible.
A one-off category or ASIN-list extract typically runs $300 to $700. An ongoing daily monitor with Buy Box and BSR tracking is usually $600 to $1,200 plus a small monthly amount, reflecting the real infrastructure cost of staying unblocked.
