Amazon Best Sellers Scraper & Rank Tracker

Track Amazon's Best Sellers and New Releases charts in 22 marketplaces, with all 100 ranks (also the ranks Amazon loads only as you scroll), and see what changed since your last run: products that climbed or fell and by how many places, new entries, re-entries, products that dropped out, days on chart, price changes, and our own Movers & Shakers computed from your runs. Products that are on both charts are flagged, and every chart gets a summary row (new entries, drop-outs, volatility, median price, brands entering and leaving). Add product details for the top products: Best Sellers Rank at every category level, brand, seller, stock, parent product and "bought in past month". Fast HTTP, from $1.50 per 1,000 products.

What you can do with it

• Find products before they peak: schedule a daily run with Changes only and get the new entries, the biggest climbers and the products that are both a New Release and a Best Seller.
• Watch your category: a summary row per chart tells you how much the top 100 moved, which brands came in or left, and where the median price went.
• Track your own products and rivals: every row says where a product was last time, how long it has been on the chart, and how its price moved.
• Build a rank history: name a history dataset and every run appends its ranks, ready to chart in Sheets or a BI tool, without a database of your own.
• Research many categories: read every department, and their subcategories to any depth, with a category limit.

Why this actor

• All 100 ranks, verified. Amazon puts only about 30 of each page's 50 products in the page itself and loads the rest as you scroll. Many scrapers return 60 of 100 or ranks without details. This actor loads the rest the way the page does and adds a coverage block to each chart summary listing any rank whose details Amazon did not serve (its rank and ASIN are still given).
• Movement, not just a list. Previous rank, places climbed, new, re-entry, dropped out, days on chart, price change and computed movers in every row; a changes-only mode where unchanged products cost $0.10 per 1,000.
• Our own Movers & Shakers. Amazon currently shows its Movers & Shakers, Most Wished For and Gift Ideas pages empty in most categories ("no movers and shakers available"). This actor still reads them when Amazon fills them (with Amazon's own percentage change), reports them as empty and never bills an empty chart, and flags the biggest climbers from your own runs (computedMover).
• Local prices. Pages are requested in the marketplace's own currency, and every row says which currency its price is in; prices in different currencies are never compared.
• Cross-chart signals. new-release-on-best-sellers, best-seller-is-new-release, new-entry-top-10 and computed-mover.
• 22 marketplaces, one language each. Pages are always requested in the marketplace's own language and currency, so a product never appears twice under two titles.
• Honest failures. A category a marketplace does not have (Amazon then shows its all-departments chart instead) is reported, not billed as data. Blocked pages are retried through datacenter and then residential proxies; Amazon's "continue shopping" interstitial is passed automatically.

Example inputs

Kitchen in the US, both charts, a daily watch for what moved:

{
  "categories": ["kitchen"],
  "charts": ["best-sellers", "new-releases"],
  "changesOnly": true,
  "monitorName": "kitchen-daily"
}

Every department in the UK and Germany, one level of subcategories, top 50:

{
  "allCategories": true,
  "subcategoryDepth": 1,
  "maxCategories": 300,
  "marketplaces": ["GB", "DE"],
  "maxItemsPerChart": 50
}

Output

A product row (a real row from 6 October 2026: the second run under the same tracking name, an hour after the first, when this product had not moved; movement is up, down, new or re-entry when it has):

{
  "recordType": "item",
  "marketplace": "US",
  "chart": "best-sellers",
  "category": "Kitchen & Dining",
  "categoryPath": ["Kitchen & Dining"],
  "rank": 31,
  "asin": "B0DCDZP98B",
  "title": "STANLEY Quencher ProTour Flipstraw Tumbler, 30 oz, Rose Quartz | Built-In Straw & Handle | …",
  "url": "https://www.amazon.com/dp/B0DCDZP98B",
  "price": 30,
  "currency": "USD",
  "rating": 4.7,
  "reviewCount": 21199,
  "previousRank": 31,
  "rankChange": 0,
  "movement": "same",
  "firstSeenOnChart": "2026-10-06T03:20:37.944Z",
  "daysOnChart": 0,
  "priceChangePercent": 0,
  "computedMover": false,
  "alsoOn": [],
  "signals": [],
  "details": {
    "bestSellersRanks": [
      { "rank": 31, "category": "Kitchen & Dining" },
      { "rank": 3, "category": "Insulated Tumblers" }
    ],
    "brand": "STANLEY",
    "soldBy": "Amazon.com",
    "shipsFrom": "Amazon.com",
    "inStock": true,
    "parentAsin": "B0FDG9B5Q8",
    "boughtPastMonth": "4K+ bought in past month"
  }
}

The first run under a tracking name is a baseline: movement fields are null and every product is returned. A dropped row names a product that left the chart (lastRank, lastSeen, firstSeenOnChart).

The chart summary from the same run (when the chart has moved, new entries, drop-outs and climbers are counted here; brandsEntering and brandsLeaving compare the brands of the detailed top products):

{
  "recordType": "chart-summary",
  "marketplace": "US",
  "chart": "best-sellers",
  "category": "Kitchen & Dining",
  "firstRun": false,
  "itemCount": 100,
  "coverage": { "ranksListed": 100, "withDetails": 100, "missingDetailRanks": [] },
  "newEntries": 0,
  "reEntries": 0,
  "dropped": 0,
  "climbed": 0,
  "fell": 0,
  "unchanged": 100,
  "volatilityPercent": 0,
  "topClimbers": [],
  "priceMedian": 17,
  "previousPriceMedian": 17,
  "priceMedianChangePercent": 0,
  "brandsEntering": [],
  "brandsLeaving": [],
  "amazonShowsEmpty": false
}

Every run writes RUN_SUMMARY to the key-value store: the outcome (COMPLETE, PARTIAL, NO_CHANGES, EMPTY or FAILED), charts read, charts Amazon shows empty, categories found, charges, warnings and failures.

Limits

• Only what Amazon shows every visitor. Sales figures are not public; "bought in past month" appears only on products where Amazon shows it, and Best Sellers Rank is Amazon's own.
• Amazon currently shows Movers & Shakers, Most Wished For and Gift Ideas empty in most categories. They are read whenever Amazon fills them; meanwhile the computed movers cover chart movement.
• A delivery postcode cannot be set without signing in to Amazon, so prices and stock are those Amazon shows to a visitor without one.
• Movement compares runs under the same tracking name; schedule them at a steady interval (daily is typical). Two runs with the same name at the same time share one memory.
• Large crawls (every department, deep subcategories) take time: Amazon answers bursts with CAPTCHAs, so requests are paced.
• Nothing found: when no chart could be read because none exists (a category or department name Amazon does not have, a chart it 404s), the run still succeeds, with one free recordType: "unreadable" row per item giving the reason; nothing is charged. A run near its time limit stops starting categories, delivers what it read and lists the rest the same way.

Changelog

• 0.1.x, reliability (2026-10-24): runs that find nothing (unknown categories or department names, missing charts) end SUCCEEDED with a free unreadable row per item saying why, instead of FAILED; a run stops starting categories before its time limit and ends with what it read, never TIMED-OUT. A run whose every chart Amazon refused still fails. Prices and events unchanged.
• 0.1.x (2026-10-23): priceMedian uses the shared median, to the cent (an even count's mean was rounded to 0.1).
• 0.1 (October 2026): Best Sellers, New Releases, Movers & Shakers, Most Wished For and Gift Ideas in 22 marketplaces; all 100 ranks; movement between runs, computed movers, cross-chart signals, chart summaries; changes-only mode; history dataset; product details.
