Practical Use Cases with SellerMagnet API

Let's explore some practical scenarios where SellerMagnet API can provide actionable insights. All examples assume you have a valid API key.

1. Competitive Analysis: Monitoring Product Statistics

Understanding a product's performance on Amazon is crucial for competitive analysis. The Amazon Product Statistics endpoint provides detailed statistics including sales rank, review counts, buy box information and historical trends. This data helps you assess the viability of entering a market or refine your existing product strategy.

Endpoint: /amazon-product-statistics

Method: GET

Example Request (cURL):

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

Example Response:

{
  "success": true,
  "data": {
    "asin": "B08N5WRWNW",
    "amazonPrice": 2999,
    "bestSellerRank": 123,
    "buyBoxPrice": 2899,
    "buyBoxFulfillment": "FBA",
    "buyBoxSellerIdHistory": [
      [
        "2024-01-01T00:00:00Z",
        "A123456789012"
      ]
    ],
    "salesRankHistory": [
      [
        "2024-01-01T00:00:00Z",
        150
      ]
    ],
    "trackingSince": "2023-01-01",
    "graphs": {
      "priceTrend": [
        {
          "timestamp": "2024-01-01T00:00:00Z",
          "price": 2999
        }
      ],
      "rankTrend": [
        {
          "timestamp": "2024-01-01T00:00:00Z",
          "rank": 150
        }
      ]
    },
    "metadata": {
      "category": "Electronics",
      "lastUpdated": "2024-07-26T12:00:00Z"
    }
  }
}

This response provides a snapshot of the product's performance, including its current price, sales rank, and buy box information. The graphs parameter allows you to generate visually compelling graphs for historical price and sales rank data.

2. Identifying Product Opportunities with ASIN Conversion

The Amazon ASIN/ISBN/EAN Converter endpoint enables you to convert between ASIN, EAN, and ISBN identifiers. This is particularly useful when sourcing products from different regions or suppliers. By converting identifiers, you can quickly identify corresponding listings on Amazon and assess their potential.

Endpoint: /amazon-asin-converter

Method: GET

Example Request (cURL):

curl -X GET 'https://sellermagnet-api.com/amazon-asin-converter?asin=9781234567890&marketplaceId=A1PA6795UKMFR9&conversion_direction=ean-to-asin&api_key=YOUR_API_KEY'

Example Response:

{
  "success": true,
  "data": {
    "asin": "B01ABCDEF2",
    "eanList": [
      "9781234567890"
    ],
    "listedSince": "2016-08-15T00:00:00Z",
    "productTitle": "Example Product Title"
  }
}

With the converted ASIN, you can then use other SellerMagnet API endpoints, such as Amazon Product Statistics, to analyze the product's sales performance and competitive landscape.

3. Monitoring Seller Performance with Review Data

Evaluating the performance of your competitors or potential partners requires insights into their seller reputation. The Amazon Seller Review endpoint provides access to seller feedback, including recent reviews and overall ratings. This helps you assess the reliability and trustworthiness of sellers on the Amazon marketplace.

Endpoint: /amazon-seller-review

Method: GET

Example Request (cURL):

curl -X GET 'https://sellermagnet-api.com/amazon-seller-review?sellerId=A1B2C3D4E5F6G7&marketplaceId=ATVPDKIKX0DER&api_key=YOUR_API_KEY'

Example Response:

{
  "success": true,
  "data": {
    "marketplace": {
      "ATVPDKIKX0DER": {
        "last5Reviews": [
          {
            "dateRated": "By John Doe on July 25, 2024.",
            "reviewText": "Great seller, fast shipping!",
            "starRating": "5 out of 5 stars"
          }
        ],
        "sellerFeedback": {
          "30": {
            "rating": "4.8",
            "reviewsCount": "15"
          },
          "90": {
            "rating": "4.7",
            "reviewsCount": "45"
          },
          "365": {
            "rating": "4.6",
            "reviewsCount": "150"
          },
          "lifetime": {
            "rating": "4.5",
            "reviewsCount": "1,500"
          }
        }
      }
    },
    "sellerId": "A1B2C3D4E5F6G7"
  }
}

Analyzing the seller's feedback scores and review text provides a comprehensive view of their reputation and service quality.
