Live data as of 2026-08-31
Amazon Best Sellers Top Rated rank_change on Trends MCP is get_top_trends with type Amazon Best Sellers Top Rated, sort rank_change, and a window such as 7d. From the August 31, 2026 pull the board stamped as_of 2026-08-31T04:01:36 UTC. Window 7d used baseline 2026-08-24T04:01:39 UTC and returned count 4. Huggies Little Snugglers Newborn Diapers sat at rank 95, prev_rank 121, rank_change 26. Windows 1d and 3d returned count 0 with a weekly-update note and baseline_ts null. Window 30d, which is also the omitted-window default, returned count 2. Passing category Toys Games on this type returned HTTP 400. Free tier access is 100 requests per month.
From the Trends MCP scan of August 31, 2026, Amazon Best Sellers Top Rated sort rank_change stamped 2026-08-31T04:01:36 UTC and filled 4 climber rows on window 7d, 10 on window 14d, and 2 on window 30d, so a default sort rank pull at limit 25 never lists these mover fields for the titles sitting past rank 25.
Top Rated 7d climbers (all 4, same as_of, baseline 2026-08-24T04:01:39 UTC):
| Current rank | Title (short) | prev_rank | rank_change |
|---|---|---|---|
| 95 | Huggies Little Snugglers Newborn Diapers | 121 | 26 |
| 10 | blink plus plan with monthly auto-renewal | 11 | 1 |
| 33 | Etekcity Food Kitchen Scale | 34 | 1 |
| 49 | Owala FreeSip Stainless Steel Water Bottle 24 oz Denim | 50 | 1 |
Default sort rank filled 25 rows at offset 0, 25 at offset 25, 25 at offset 50, 25 at offset 75, 25 at offset 100, 25 at offset 125, 25 at offset 175, then count 0 at offset 200, closing at rank 200. Rank 1 was Amazon Basics 48-Pack AA Alkaline High-Performance Batteries. Rank 2 was Amazon Basics AAA Long-Lasting Alkaline Batteries, 36-Count. Rank 3 was Verity. Rank 4 was Crocs Unisex-Adult Classic Clog. None of those four current-rank leaders appear on the 7d climber list.
Huggies Little Snugglers sat at rank 95, the twentieth title on the offset 75 page. BONAOK Wireless Bluetooth Karaoke Microphone, the 30d leader, sat at rank 140 on the offset 125 page. Earth Rated Dog Wipes, the 14d leader, sat at rank 176 on the offset 175 page. Default limit 25 stops at Dickies Men's Dri-tech Original Moisture Control Crew Socks and never prints ranks 95, 140, or 176. The current-rank catalog is documented on the Amazon Best Sellers API.
limit 50 on the same 7d call still returned count 4. Offset 25 then returned count 0 with the note that no items on the current board climbed versus the 7d baseline; everything held or fell. Raising limit does not invent extra climbers after the list is exhausted. 14d and 30d repeated that pattern: limit 50 still 10 and 2, offset 25 still held-or-fell.
Three of the four Top Rated 7d climbers are the better slot of a title that occupies two consecutive current ranks, so rank_change 1 on this stamp often means a duplicate listing rather than a new product entering the board.
On default sort rank, blink plus plan with monthly auto-renewal sat at rank 10 and rank 11. Etekcity Food Kitchen Scale sat at 33 and 34. Owala FreeSip 24 oz Denim sat at 49 and 50. STANLEY Quencher H2.0 Tumbler 30 oz Rose Quartz sat at 27 and 28. Theo of Golden sat at 35 and 36. TERRO Liquid Ant Killer Bait Stations 12-Pack sat at 39 and 40. Dungeon Crawler Carl sat at 87 and 88. Alpha Grillers Instant Read Meat Thermometer sat at 116 and 117.
The 7d payload then reported blink at rank 10 from prev_rank 11, Etekcity at 33 from 34, and Owala Denim at 49 from 50. Window 14d went further: Alpha Grillers appeared three times in the same climber array, at rank 116 from 118 (rank_change 2), rank 116 from 117 (rank_change 1), and rank 117 from 118 (rank_change 1). Rank 116 is listed twice inside one rank_change response. Deduplicate on keyword before treating the array as unique products.
Huggies Little Snugglers is the exception on 7d. It sat once, at rank 95, and climbed from 121. That is the only double-digit Top Rated 7d move on this stamp.
A short rank_change window on Amazon Best Sellers Top Rated can fail before it compares ranks, because 1d and 3d on this stamp set baseline_ts to null and returned count 0 with a weekly-update note, while 7d, 14d, and 30d set a baseline and returned climbers.
| Window | baseline_ts | Count | Note |
|---|---|---|---|
| 1d | null | 0 | no baseline within 1 days of 2026-08-30; feed updates roughly weekly; retry 30d |
| 3d | null | 0 | no baseline within 1 days of 2026-08-28; same weekly retry 30d |
| 7d | 2026-08-24T04:01:39 | 4 | filled; limit 50 still 4 |
| 14d | 2026-08-17T04:01:33 | 10 | Earth Rated Dog Wipes +4 at rank 176 |
| 30d (and omitted window) | 2026-08-03T04:01:36 | 2 | BONAOK karaoke microphone +38 at rank 140 |
The 1d note is not the held-or-fell sentence used at 7d offset 25. It is a missing-baseline body: no snapshot within 1 days of 2026-08-30 for type Amazon Best Sellers Top Rated, the feed updates roughly weekly, retry window 30d. The 3d body reused the "within 1 days" wording, this time against 2026-08-28. Empty is a real JSON body. The retry string names 30d, yet 7d already returned 4 rows. Call 7d before spending a 30d page if the question is last week's climbers.
Window 30d returned fewer climbers than window 7d (2 versus 4) and fewer than 14d (2 versus 10). A longer lookback is not a larger mover list on this stamp. The 30d leader, BONAOK Wireless Bluetooth Karaoke Microphone at rank 140 from 178, rank_change 38, does not appear on 7d or 14d. The 14d leader, Earth Rated Dog Wipes at rank 176 from 180, rank_change 4, does not appear on 7d. Each window is its own comparison, not a superset.
Toys Games 1d on type Amazon Best Sellers by Category returned the same weekly note, with the type string swapped, against the same "within 1 days of 2026-08-30" target. Details for department boards live on Amazon Best Sellers by Category rank_change.
get_top_trends with type Amazon Best Sellers Top Rated, sort rank_change, and window 7d returns climber objects with rank, keyword, prev_rank, and rank_change. REST mode get_top_trends bills that call as one request per page. Those objects have no category_path field. Passing category on this type is rejected.

A 7d call that also sent category Toys Games returned HTTP 400 invalid_request. The message listed five types that accept category: Amazon Best Sellers by Category, Google Trends by Category, Substack by Category, TikTok Trending Hashtags by Category, and Top Websites. Amazon Best Sellers Top Rated is not on that list. Offset and limit still apply; page math lives on get_top_trends offset and limit.
sort rank_change with window 7d is valid on official Amazon department boards from the same account, and on this August 31, 2026 stamp those boards shared as_of 2026-08-31T04:01:36 UTC and baseline 2026-08-24T04:01:39 UTC while filling denser climber lists than Top Rated.
Toys Games 7d returned 8 climbers, each with category_path Toys Games. Infinno Wrist Rattles and Foot Finder Socks Set sat at rank 19 from 24, rank_change 5. Bezente Assorted Latex Rainbow Balloons 100 Pack sat at rank 5 from 9, rank_change 4. Crayola Globbles Fidget Toy sat at rank 22 from 25, rank_change 3. Bright Starts Oball Easy Grasp Classic Ball sat at rank 12 from 14, rank_change 2. The largest Toys Games 7d climb (+5) is smaller than Top Rated's Huggies +26, but every Toys Games mover sat inside ranks 5 through 22, inside one limit 25 page.
Electronics 7d returned 17 climbers. CHCORE Surge Protector Power Strip sat at rank 13 from 52, rank_change 39. Amazon Fire TV Stick 4K Select sat at rank 8 from 43, rank_change 35. Amazon Fire TV Stick 4K Plus sat at rank 4 from 20, rank_change 16. Amazon Fire TV Stick HD sat at rank 6 from 14, rank_change 8. Amazon Echo Dot sat at rank 15 from 23, rank_change 8. Apple AirTag (2nd Generation) sat at rank 2 from 3, rank_change 1. Several Electronics climbers sit past default limit 25, same pattern as Top Rated Huggies, but the largest Electronics moves are still inside the first page.
Top Rated rank_change on this stamp is a sparse, often duplicate-slot sort on a 200-row mixed catalog. It is not a substitute for a department call. For filtered 1-N current ranks, see the Amazon Best Sellers by Category API.
A Best Sellers climber row is a title plus ranks. Search demand needs a second get_growth call, and source amazon on this pull used 49 monthly points with recent_date 2026-07-31, so preset 7D returned error collapsed_range.
Huggies on amazon sat at index 75.8 with volume 1,299,341 on 2026-07-31, down 3.19% over 30 days from 78.3 (volume 1,342,392), up 6.91% over 3 months from 70.9 (volume 1,215,148), down 16.89% over 12 months from 91.2 (volume 1,562,875). google search for Huggies sat at 72.0 on 2026-08-22, up 2.86% over 7 days from 70.0, down 2.7% over 30 days from 74.0, across 261 weekly points. The Top Rated 7d +26 climb and the monthly amazon -3.19% search move are different clocks.
Owala on amazon sat at 78.8 with volume 11,067,682, up 26.69% over 30 days from 62.2 (volume 8,729,602), up 51.54% over 3 months from 52.0 (volume 7,307,060). google search sat at 87.0 on 2026-08-29, flat over 7 days from 87.0, up 14.47% over 30 days from 76.0, up 50.0% over 3 months from 58.0. The Denim 24 oz listing can occupy ranks 49 and 50, report a +1 climb, and still sit next to a rising monthly search series.
Crocs on amazon sat at 52.6 with volume 9,187,782, down 27.95% over 30 days from 73.0 (volume 12,765,263). google search sat at 87.0 on 2026-08-22, down 2.25% over 7 days from 89.0, flat over 30 days from 87.0. Verity on amazon sat at 28.1 with volume 124,450, up 10.63% over 30 days from 25.4. google search sat at 63.0 on 2026-08-29, down 4.55% over 7 days from 66.0, up 3.28% over 30 days from 61.0, up 350.0% over 3 months from 14.0. Rank 3 on Top Rated can be a book with a three-month google search spike and zero 7d rank_change.
blink on amazon sat at 37.7 with volume 2,686,045, down 36.96% over 30 days from 59.8. google search sat at 26.0 on 2026-08-29, flat over 7 days, down 3.7% over 30 days from 27.0. karaoke microphone on amazon sat at 8.8 with volume 66,929, up 25.71% over 30 days from 7.0, up 18.92% over 3 months from 7.4. Earth Rated on amazon sat at 69.2 with volume 85,914, down 4.95% over 30 days from 72.8. The 30d BONAOK +38 climb sits next to a small monthly amazon series. The 14d Earth Rated +4 climb sits next to a falling monthly index.
