"AbuseIPDB": {
  "APIEndpoint": "",
  "APIKey": "<apikey>"

public HomeController(ILogger<BlogController> logger, IAbuseIPDBClient abuseIPDBClient, IHttpContextAccessor httpContextAccessor)

To lookup the requester IP of a request in and reject IPs with an abuse confidence score of 70 or higher:

var ip = httpContextAccessor.HttpContext.Features.Get<IHttpConnectionFeature>()?.RemoteIpAddress;
    // skip for local loopback
    if (!IPAddress.IsLoopback(ip))
        var cancellationTokenSource = new CancellationTokenSource(TimeSpan.FromSeconds(30));
        (Check abuseCheck, _) = await abuseIPDBClient.CheckAsync(ip.ToString(), 90, false, cancellationTokenSource.Token);

        if (abuseCheck.AbuseConfidenceScore > 70)
            var error = new ErrorModel
                Title = "Bad Request.",
                Detail = "User IP is blocked due to abuse.",
                Instance = $"/action/{Activity.Current?.Id ?? httpContextAccessor.HttpContext.TraceIdentifier}",
                Status = 400,
                Type = "/action/abusiveip"

            // return a 400 with the error information
            return Unauthorized(error);
catch (OperationCanceledException)
    // request timed out.
catch (ApiException abuseIPException)
    // abuse ip db threw an exception
