Whereas you already have the Key API and it is enabled, in short:
var query = 'mutant giant spider dog'
gapi.client.load('youtube', 'v3', function() {
gapi.client.setApiKey('[SUA_CHAVE_API]');
var request = gapi.client.youtube.search.list({
part: 'snippet',
q: query,
maxResults: 1
});
request.execute(function(response) {
$.each(response.items, function(i, item) {
var idVideo = item['id']['videoId'];
var urlVideo = "https://www.youtube.com/embed/" + idVideo;
//FAZ O QUE QUISER COM OS DADOS. title, description,..
});
});
});
I set maxResults to 1 to bring the most relevant video based on the name, so passing the full name must be the first one on the list. But if you want to iterate through the list increase the maxResult as in jsfiddler below.

Note: remember to load the Jquery and API Google
============================================================
The query via C# is very similar too:
YoutubeService youtube = new YoutubeService(new BaseClientService.Initializer() {
ApiKey = credentials.ApiKey
});
SearchResource.ListRequest listRequest = youtube.Search.List("snippet");
listRequest.Q = CommandLine.RequestUserInput<string>("Search term: ");
listRequest.Order = SearchResource.Order.Relevance;
SearchListResponse searchResponse = listRequest.Fetch();
foreach (SearchResult searchResult in searchResponse.Items)
{
//USE OS RESULTADOS COMO DESEJAR
}
