How this service works
Amazon best sellers list for any category, current or historical. Ordered ASIN list of best sellers in a category (up to 500,000 for root categories, 10,000 for sub-categories), ranked by current sales rank, by 30/90/180-day average rank, or for a past month. Deeper than the public Best Sellers page (top 100). Not charged if no list exists.
Output
A JSON object containing an array of ASIN strings ordered by the requested rank metric, the total count of ASINs in the list, the resolved category ID, and metadata including whether the result was cached, the price paid, and the marketplace domain ID. Returns up to 500,000 ASINs for root categories and 10,000 for sub-categories.

Technical details
Endpoint
GEThttps://asin402.com/api/data/bestsellers?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need Amazon best-seller rankings that go far deeper than the public top-100 page — ideal for product research, catalog analysis, or competitive intelligence across any Amazon marketplace. It is especially valuable when you need historical monthly rankings or multi-day average ranks (30/90/180-day) rather than just a snapshot of current rank. Prefer this over general Amazon search endpoints when the goal is to retrieve a ranked popularity list for an entire category rather than matching specific keywords.
Side effects
- No list exists for the requested category/date combination — endpoint returns no charge and an empty or null result
- Invalid category node ID — returns an error or empty list
- Unsupported marketplace domain — returns validation error
- Invalid month/year combination (outside 36-month historical window) — returns error
- Exceeding allowed limit values — may return validation error or default behavior
