Keepa API Framework
==============================

This framework is intended for users of the Keepa API.

<a name="features"></a>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

Maven
-----
```xml
<repositories>
	<repository>
		<id>Keepa</id>
		<name>Keepa Repository</name>
        <url>https://keepa.com/maven/</url>
    </repository>
	...
</repositories>

<dependencies>
	<dependency>
		<groupId>com.keepa.api</groupId>
		<artifactId>backend</artifactId>
		<version>LATEST</version>
	</dependency>
	...
</dependencies>
```

Gradle
-----
```xml
repositories {
  ...
  maven { url 'https://keepa.com/maven/' }
}
dependencies {
  ...
  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.
```

<a name="examples"></a>Quick Example
==============

<a name="examples-keepa-api"></a>Make an API request
---------------------------

```java
KeepaAPI api = new KeepaAPI("YOUR_API_KEY"); // the KeepaAPI object is reuseable
Request r = Request.getProductRequest(AmazonLocale.US, 90, null, "B001GZ6QEC");

api.sendRequest(r)
		.done(result -> {
			switch (result.status) {
				case OK:
					// iterate over received product information
					for (Product product : 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 stdout
							int currentAmazonPrice = ProductAnalyzer.getLast(product.csv[Product.CsvType.AMAZON.index], Product.CsvType.AMAZON);

//check if the product is in stock -1 -> out of stock
							if (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 Amazon
							int weightedMean90days = 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));
