Historically, developers looked for "XML downloads" of video feeds. With API v3, you request data via a URL, and Google returns a structured format (usually JSON, which has replaced XML as the standard, though XML can still be parsed).
To get a list of the "Top" videos (for example, the most popular videos in a specific category), you construct a URL using your new key. youtube api keyxml download top
The Request URL format:
https://www.googleapis.com/youtube/v3/videos?part=snippet,contentDetails,statistics&chart=mostPopular®ionCode=US&key=[YOUR_API_KEY_HERE]
Breaking down the parameters:
Install tools (choose one):
#!/bin/bash
API_KEY="YOUR_KEY"
OUTPUT_FILE="youtube_top_$(date +%Y%m%d).xml"
curl -s "https://www.googleapis.com/youtube/v3/videos?part=snippet,statistics&chart=mostPopular&maxResults=50&key=$API_KEY"
| python3 -c "import sys, json, xml.etree.ElementTree as ET; data=json.load(sys.stdin); root=ET.Element('feed'); [ET.SubElement(root, 'entry', id=i['id']).extend([ET.Element('title', text=i['snippet']['title']), ET.Element('views', text=i['statistics'].get('viewCount','0'))]) for i in data['items']]; print(ET.tostring(root, encoding='unicode'))"
> $OUTPUT_FILE Save the following as youtube_top_downloader
echo "Saved to $OUTPUT_FILE"
You cannot proceed without a valid API Key. The "KeyXML" part of your search implies that the API key will be passed as a parameter in an XML request.
Once you master the basic download top workflow, scale your data extraction: Breaking down the parameters:
