To force all json data returned from api to camel case it's easier to use Newtonsoft Json with the default camel case contract resolver.

Create a class like this one:

using Newtonsoft.Json.Serialization;

internal class JsonContentNegotiator : IContentNegotiator
{
    private readonly JsonMediaTypeFormatter _jsonFormatter;

    public JsonContentNegotiator(JsonMediaTypeFormatter formatter)
    {
        _jsonFormatter = formatter;          
        _jsonFormatter.SerializerSettings.ContractResolver =
            new CamelCasePropertyNamesContractResolver();
    }

    public ContentNegotiationResult Negotiate(Type type, HttpRequestMessage request, IEnumerable formatters)
    {
        return new ContentNegotiationResult(_jsonFormatter, new MediaTypeHeaderValue("application/json"));
    }
}

and set this during api configuration (at startup):

var jsonFormatter = new JsonMediaTypeFormatter();
httpConfiguration.Services.Replace(typeof(IContentNegotiator), new JsonContentNegotiator(jsonFormatter));
