youtube api for getting list of monetized vidoes

I would like is to be able to search youtube for any given keyword or Channel, and for the results to show in a list basic information about the video, including video title, number of views, number of comments, when the video was posted and which videos are currently monetized. What I would then like to be able to do is create a list of all the monetized videos along with the URL's..
Can anyone knows how to do it?
I don't see any documentations regarding your concern. I only checked on this documentation that you can only get a list of videos that match the API request parameters using Videos: list. You can only get channelId, title, description, tags, and categoryId. You may check this thread on how to check monetized and non-monetized videos from my YouTube channel. You may also read this Monetization Guidelines from YouTube.

Youtube api v3 - list of deleted vids

we are using the youtube api to keep track of youtube videos. currently we "watch" around 30k videos. now we have the issue that we want to figure out which videos have been deleted. is there some way to get e.g. a list of all deleted vids of a channel or some other way?
sending a single request (and handling 404) for each video doesn't seem to be a good idea.
I guess you can not do it with only youtube api.
You can create your own database of all your videos and channels and periodically sync it with youtube to check what video status changed or not exists in list anymore.
Youtube API has method Videos.list, it returns list of all your videos.
Another tricky way: load every video url and check the size of content instead of parsing html.
If video exists then content size about 50kb, if not - 15kb. It seems youtube do not pass Content-Length header. That's why you need to load content to check size.
But I prefer the first way.

Output last and popular youtube videos on site ? any api?

I want to output last videos and popular videos of my youtube channel.
Is there any standart widget, api method for this?
Based on this answer, you can use the YouTube Data V3 API to get the uploads playlist ID, which you can then use to get the latest videos in that playlist. You can change the value of maxResults to return however many videos you want (from 0 to 50).
Use the search:list method to get your most viewed videos by specifying the channel ID and setting order=viewcount (not quite sure what you want when you say popular videos, you could also set order=rating to get the highest rated videos). This video might also help you out.

YouTube API Search by Tags

I'm trying to add videos to an existing ASP.NET MVC site, and I'd like to show videos from our YouTube channel.
I have added a tag to each video to indicate what page it should appear on. I had thought that I could search our channel by tag on each page to render the relevant video on that page.
I'm trying to exclusively use the API v3, but it seems I can't do this.
I can't use developer tags, because videos are uploaded by multiple users using the standard YouTube front end. This seems like basic functionality, so I'm assuming it's my inexperience with this API.
As an example, our YouTube channel is ChillinWithCharlie. During development, one video is tagged 20141213Cheneys.
I can get all videos in our channel, but is there a way to query the v3 API to retrieve just this video?
I've seen one suggestion here that I retrieve all videos, and filter in code. This feels inefficient, so I'd rather not do this, but I can't even see where the tag is returned with all channel videos, that I could interrogate in code.
It's not just you. There seems to be no specific query parameter to search by tag with API v3.
I would recommend doing a search with your tag in the 'q' (search) parameter, then checking the results to see if the tag exists in the returned snippet->tags property to verify the exact video.
Note YouTube tags are only visible to the video's uploader.

PHP Youtube API v3 Missing Description in Playlist Items

I'm not getting the description form my uploaded videos when i query them via Youtube Data API v3 using OAuth 2.0 and the sample code provided here https://developers.google.com/youtube/v3/docs/playlistItems/list.
Could this be a bug? None of my videos are private and the only thing that is missing from the response is the video's description!
I'm using the PHP library and the "part" parameter is snippet (don't know if this helps).
Thanks in advance.
I believe this is intended, since video descriptions are not displayed when viewing playlists on YouTube.
If you wish to include the description of your uploaded videos, consider using YouTube API v3 Search: list instead. An ellipsis-truncated description will be provided for your videos under snippet/description. Again, this behaviour is similar to searching on YouTube, where descriptions are cut off.
If a full description is required, you'll need to use Videos: list.
Alternatively, use version 2 of the API: https://gdata.youtube.com/feeds/api/users/youtube_username/uploads?max-results=50&start-index=1.
