# Best Sellers Rank

> Get an Amazon product's Best Sellers Rank in its main category and subcategories with one Real-Time API request by ASIN.

Source: https://docs.easyparser.com/real-time-integration/best-sellers-rank

The Best Sellers Rank operation (`BEST_SELLERS_RANK`) returns a product's current Best Sellers Rank on Amazon, together with basic product details. You identify the product by its `asin` and the marketplace by its `domain`.

## When to use

- Track a product's rank over time by polling it on a schedule and storing each snapshot.
- Compare your products with competitors in the same category or subcategory.
- Check demand for a product type before you list or source it.
- Spot products whose subcategory rank improves quickly.
- Audit the ranks of a whole catalog with the [Bulk API](/bulk-integration/overview).

## What the response includes

The response structure depends on the operation version. Version `2` is the Live version since November 1, 2026, so requests without `operation_version` receive it. It responds faster and includes subcategory ranks. Version `1` is the legacy structure (see [Operation Versioning](/essentials/operation-versioning)).

Version `2`:

- Product identification: `asin`, short `title`, `brand_name`, `manufacturer` and the product `link`.
- Main category and subcategory rank summary, each with its category title and Best Sellers list link (`bestseller`).
- Every Best Sellers list the product is ranked in, with rank, title, link and level (`bestsellers`).
- The full-resolution main image (`image`).

Version `1` (legacy):

- Product identification and commercial data: `asin`, full `title`, `brand_name`, `price`, `currency` and `link`.
- Main category rank, category name and subcategory browse node ID (`bestseller`).
- Primary image and thumbnail links (`media`).
- Rating summary (`reviews`).

See the [Best Sellers Rank response](/real-time-integration/best-sellers-rank/response) for all fields and the migration table.

> **INFO:** Version `2` does not return price, currency or review data. If you need them, use the Detail operation (`DETAIL`). See the [Detail response](/real-time-integration/detail/response).

## Credit cost

Each successful request costs 1 credit, in both versions. See [Credit Consumption](/essentials/credit-consumption).
