Visit the official Shodan API documentation at:
This is still in active development, error handling might not well handle well. Best bet when working with any libraries you didn't write..harden your calls!
Installation
install-package Shodan.Net
Getting started
You need to have an Api key. Get your api key here.
Create a shodan client. Note that ShodanClient inerhits from IDisposable, so you should wrap it in a using, or make sure it will be disposed. Shodan client is thread safe, so you should be able to keep 1 object around for many requests.
var client = new Shodan.Net.ShodanClient("myapiKey");
Now just query away.
await client.GetPortsAsync();
await client.GetHostAsync("172.1.1.0");
await client.GetMyIpAsync();
Searching
Searching shodan requires you to build up queries, and facets to make it easier we have used a generator pattern to produce queries.
await client.SearchHosts(
query: a => a.Withcity("boston")
.Withcountry("usa")
.Before(DateTime.Now.AddDays(-5)),
facet: b => b.WithAsn()
);
