Features

✓

50 items per page

Each /v1/amazon/best-sellers call returns up to 50 ranked items for the chosen category — a full top-50 leaderboard in a single request.

✓

Best sellers, hot new releases, and high-rated modes

The type parameter switches between BEST_SELLERS, HOT_NEW_RELEASES, and HIGH_RATED rankings, so one endpoint serves three distinct Amazon charts.

✓

Rank + rank-change label per product

Each item carries its numeric rank plus a rank-change label, letting you track movers up and down the chart hour over hour.

✓

Use category slugs from /v1/amazon/categories

The required category parameter takes a slug (e.g. software) sourced from the Amazon Categories API, keying every ranking to Amazon's official taxonomy.

✓

Hourly-refreshed data (1h cache)

Best-seller ranks are refreshed by Amazon roughly hourly, and responses are cached for 1 hour to match — fresh leaderboards without redundant calls.

  method: 'POST',

    'x-api-key': 'YOUR_API_KEY',
    'Content-Type': 'application/json',

The Amazon Best Sellers API for category rankings

The YepAPI Amazon Best Sellers API returns Amazon's ranked leaderboards as structured data. Pass a category slug like software and a type to /v1/amazon/best-sellers and get back up to 50 ranked items — each with rank, ASIN, title, price, star rating, and rating count — at $0.01 per call.

This is ranking data, not a product lookup or a discount feed. The type parameter switches between BEST_SELLERS, HOT_NEW_RELEASES, and HIGH_RATED, and because Amazon refreshes ranks roughly hourly, it's the endpoint for trend spotting, launch research, and live "Top 10 in X" affiliate pages.

What is an Amazon Best Sellers API?

An Amazon Best Sellers API returns Amazon's ranked product charts for a category as structured data. For a given category slug you get a leaderboard of up to 50 items, each with its rank, a rank-change label, ASIN, title, price, and rating, across three modes: best sellers, hot new releases, and high-rated. It exists because rank is a unique, time-sensitive signal that no single-product lookup captures — it tells you not what a product is, but how it's performing against everything else in its category right now, refreshed hourly.

Build your own best-seller tracker

Call /v1/amazon/best-sellers on an hourly schedule, store the rank for each ASIN, and chart how products climb or fall the leaderboard over time. The category parameter takes a slug from the Amazon Categories API, the type parameter lets you watch new releases separately from established sellers, and each ASIN deep-links into Product Details or Reviews. It's a complete trend-spotting pipeline on one YepAPI key that also covers SEO and SERP data.

Amazon Best Sellers API pricing — $0.01 per call

Best Sellers costs $0.01 per call for a full top-50 ranking, and responses are cached for 1 hour to match Amazon's own refresh cadence — so hourly polling stays both fresh and cheap. No quotas or monthly minimums. Keepa includes historical rank graphs inside a subscription; if you'd rather pay per ranking you pull and avoid a recurring tier, YepAPI's per-call rate is the leaner option for live leaderboards.

Rank movement and three ranking modes

What makes Best Sellers distinct is rank itself, plus the rank-change label that turns a snapshot into a trend. Switching type between BEST_SELLERS, HOT_NEW_RELEASES, and HIGH_RATED gives you three different lenses on a category — what's selling, what's newly launched, and what's most loved — all keyed to Amazon's official hourly-refreshed charts. That's the data founders use to vet a market before launch and affiliates use to keep "Top 10" pages current.
