[Amazon Best Sellers] Top-50 ranking for a category with 24h rank deltas.
Use when: user says "X category bestsellers" / "who's #1 in X" / "any new entrants climbing" / "benchmark top sellers"; setting baseline products during niche scouting; tracking category leadership in competitor radars.
Don't use: for new arrivals (use list_new_releases); for full category listings beyond top 50 (use list_category_products); when you only have a keyword (use search_categories first).
Returns: data.json[0].data.{ reftag, recsList } — recsList is a JSON-string array (parse twice); each row { id, metadataMap.{ render.zg.rank, currentSalesRank, percentageChange, twentyFourHourOldSalesRank } }.
Pair with: ↑ categorySlug from user or scene inference (e.g. 'electronics' / 'home-garden' / 'beauty'); ↓ feed id (ASIN) into get_amazon_product for single-product deep-dive.
Cost: ~1 point/call, ~5s.
Tips: categorySlug is the hyphenated English slug in amazon.com/Best-Sellers URL paths.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| categorySlug | string | yes | Amazon Best Sellers category slug (lowercase, hyphenated). Examples: 'electronics', 'home-garden', 'beauty', 'toys-and-games'. Find these in the URL path on amazon.com/Best-Sellers. |
| site | string | no | Amazon marketplace. Defaults to amz_us. |
| zipcode | string | no | ZIP code that must match the site country (amz_us → US zip, amz_jp → JP zip, ...). Optional; backend picks a random one from the per-country pool when omitted. Cross-country zips (e.g. amz_us + JP zip) are rejected by the backend. Examples: 10001 (NY) / 90001 (LA) / 100-0001 (Tokyo). |
| format | string | no | Response format. Defaults to 'json' — structured Top-50 ranked ASIN list. Use 'markdown' for the rendered page text. |
| clientSource | string | no | 调用来源标记。仅由 Pangolinfo Skill 传 skill；普通 MCP 调用省略即可。 |
