Accessing the API should be very simple.
There are only two REST calls, one creates a new game to obtain a game id and a player id. The other method to make moves.

If you are unfamiliar with REST you should take a look at the code below.

You can also access API documentation at this site.

public class Example
    private HttpClient HttpClient { get; set; }
    public void Init()
        HttpClient = new HttpClient
            BaseAddress = new Uri("http://airobotsrestservice.azurewebsites.net")
            new MediaTypeWithQualityHeaderValue("application/json"));

    public void FindExit()
        var userId = "c9356e13-d74b-4756-8c23-90c5bee67b53"; //Please use your own user id. ;)
        var ng = Get<NewGame>($"/api/User/{userId}/NewGame");
        var gameId = ng.GameId;
        var playerId = ng.PlayerId;
        var ai = new AI();
        while (!ai.ExitFound)
            var direction = ai.GetBestDirection();
            var nextView = Get<string>($"/api/Player/{playerId}/Game/{gameId}/Move/{direction}");
            if (!ai.ExitFound)
    T Get<T>(string path)
        var responseTask = HttpClient.GetAsync(path);
        var response = responseTask.Result;
        var task = response.Content.ReadAsStringAsync();
        if (response.IsSuccessStatusCode)
            return JsonConvert.DeserializeObject<T>(task.Result);
        throw new ApplicationException($"Unseccessfull response {response.StatusCode}.{task.Result});

    class NewGame
        public Guid GameId { get; set; }
        public string BotView { get; set; }
        public int PlayerId { get; set; }
