For the purpose of me trying to understand the Greynoise API, I implemented it (kind of) in Java (because I like Java's objects).
I don't have an enterprise api key so I have zero clue if any of those methods work.
Normally I host my libraries on some sort of repository. Due to the nature of this project, I'm not, as of currently, deploying it to central.
$ mvn clean package
or
$ ./mvnw clean package
// This creates a community client without an API key.
// However, an api key may be provided inside this method.
GreynoiseClient client = GreynoiseClient.community();
// Get the host information of the ip address 8.8.8.8, and when
// the promise resolves, print the data.
client.getHostInformation("8.8.8.8").onSuccess(System.out::println)// It is required that you have an API key to use the enterprise client.
// If the key is empty, the library will fail to create the client.
String apiKey = System.getenv("ENTERPRISE_KEY");
GreynoiseClient client = GreynoiseClient.enterprise(apiKey);
client.getQuickHostInformation("1.1.1.1", "8.8.8.8", ...);
