Keepa API Framework

This framework is intended for users of the Keepa API.

Features

• Retrieves content from the API asynchronously and in parallel via Deferred callbacks (Java 8 Lambda friendly)
• Parses API response to easy to use Java objects
• Provides methods that facilitate the work with price history data

compile 'com.keepa.api:backend:latest.release'
}
Also consider to add
configurations.all {
resolutionStrategy {
cacheDynamicVersionsFor 0, 'seconds'
cacheChangingModulesFor 0, 'seconds'
}
}
Which makes sure that the newest version from our servers is pulled during build.

Quick Example

Make an API request

KeepaAPIapi = newKeepaAPI("YOUR_API_KEY"); // the KeepaAPI object is reuseableRequestr = Request.getProductRequest(AmazonLocale.US, 90, null, "B001GZ6QEC");
api.sendRequest(r)
.done(result -> {
switch (result.status) {
caseOK:
// iterate over received product informationfor (Productproduct : result.products){
// System.out.println(product);if (product.productType == Product.ProductType.STANDARD.code || product.productType == Product.ProductType.DOWNLOADABLE.code) {
//get basic data of product and print to stdoutintcurrentAmazonPrice = ProductAnalyzer.getLast(product.csv[Product.CsvType.AMAZON.index], Product.CsvType.AMAZON);
//check if the product is in stock -1 -> out of stockif (currentAmazonPrice == -1) {
System.out.println(product.asin + " " + product.title + " is currently out of stock!");
} else {
System.out.println(product.asin + " " + product.title + " Current Amazon Price: " + currentAmazonPrice);
}
// get weighted mean of the last 90 days for AmazonintweightedMean90days = ProductAnalyzer.calcWeightedMean(product.csv[Product.CsvType.AMAZON.index], KeepaTime.nowMinutes(), 90, Product.CsvType.AMAZON);
...
} else {
...
}
}
break;
default:
System.out.println(result);
}
})
.fail(failure -> System.out.println(failure));
