Practical Use Cases and Examples

1. Tracking Sales Rank History

The sales rank of a product is a key indicator of its popularity and sales performance. SellerMagnet API allows you to retrieve the historical sales rank data for any Amazon product using the Amazon Product Statistics endpoint.

Here’s how you can retrieve the sales rank history for a product:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-statistics?asin=B08N5WRWNW&marketplaceId=A1PA6795UKMFR9&api_key=YOUR_API_KEY'

Response example:


{
  "success": true,
  "data": {
    "asin": "B08N5WRWNW",
    "amazonPrice": 2999,
    "bestSellerRank": 1234,
    "buyBoxPrice": 3000,
    "buyBoxFulfillment": "FBA",
    "buyBoxSellerIdHistory": [
      [
        "2024-01-01T00:00:00Z",
        "A1234567890123"
      ],
      [
        "2024-01-02T00:00:00Z",
        "A4567890123456"
      ]
    ],
    "salesRankHistory": [
      [
        "2024-01-01T00:00:00Z",
        1200
      ],
      [
        "2024-01-02T00:00:00Z",
        1234
      ]
    ],
    "trackingSince": "2023-12-01",
        "graphs": null,
        "metadata": null
  }
}

This data can be used to plot trends in sales rank over time, providing valuable insights into the product's lifecycle stage. You can also use the graphs=true parameter to generate visually graphs for history data.

2. Monitoring Buy Box Price and Fulfillment

The Buy Box is a critical element of Amazon sales. Tracking its price and fulfillment method can provide insights into competitive dynamics.

Use the Amazon Product Statistics endpoint to monitor these changes:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-statistics?asin=B07XJ8C5LL&marketplaceId=ATVPDKIKX0DER&api_key=YOUR_API_KEY'

By analyzing the buyBoxPrice and buyBoxFulfillment fields over time, you can understand how pricing strategies and fulfillment methods impact product sales. Additionally, buyBoxSellerIdHistory provides a chronological list of Buy Box seller changes, including timestamps and seller IDs.

3. Analyzing Product Review Trends

Customer reviews significantly influence buying decisions. Monitoring review counts and ratings can indicate changes in product perception.

To monitor the reviews, use the data provided in Amazon Product Statistics combined with Amazon Product Lookup:


curl --location --request GET 'https://sellermagnet-api.com/amazon-product-lookup?asin=B07XJ8C5LL&marketplaceId=ATVPDKIKX0DER&api_key=YOUR_API_KEY'

Analyze the reviews object to see trends in average rating and total reviews.

4. Identifying Product Introduction and End-of-Life

The trackingSince field in Amazon Product Statistics indicates when SellerMagnet began tracking the product. While not the exact listing date, it provides a good approximation of when the product became significant. The Amazon Product Lookup gives the listedSinceDate which indicates when the product was first listed.

Monitor sales rank and review trends to identify products nearing the end of their lifecycle. A consistent decline in sales rank and a slowdown in review accumulation may indicate a product is losing market relevance.
