Introduction

Now that I have a chance to touch the YouTube Data API, I would like to summarize the information.

What is the YouTube Data API?

https://developers.google.com/youtube/v3/docs

With the API provided by YouTube, you can get information such as videos and channels and use it on your website or application. Please note that the upper limit of API usage (quota) per day is 10000.

Get the API key

Create a project on Google Cloud Platform

From here (https://console.cloud.google.com/projectcreate?hl=ja) Create a project.

The project name is arbitrary, ** Don't forget to change the project ID. ** **

Enable YouTube Data API v3

Enable the YouTube Data API because it will be used in the created project.

From here Valid after selecting a project To.

Creating credentials

From here (https://console.cloud.google.com/apis/api/youtube.googleapis.com/credentials?hl=ja) Create an API key.

Make a note of the API key you created, as it will be used when you actually use the API.

Try to get various information with YouTube Data API

Install the required packages

Use pyenv to change the version of python.

$ pyenv install 3.8.3
$ pyenv local 3.8.3

Install the package to use the YouTube Data API.

$ pip install google-api-python-client==1.9.3

Search YouTube channel information

#!/usr/bin/env python
# -*- coding: utf-8 -*-

import json

from apiclient.discovery import build

API_KEY = '<Enter the API key you got last time>'
YOUTUBE_API_SERVICE_NAME = 'youtube'
YOUTUBE_API_VERSION = 'v3'
SEARCH_TEXT = '<Channel name you want to search>'

youtube = build(
    YOUTUBE_API_SERVICE_NAME,
    YOUTUBE_API_VERSION,
    developerKey=API_KEY
)

response = youtube.search().list(q=SEARCH_TEXT, part='id,snippet', maxResults=25).execute()

for item in response.get('items', []):
    if item['id']['kind'] != 'youtube#channel':
        continue
    print('*' * 10)
    print(json.dumps(item, indent=2, ensure_ascii=False))
    print('*' * 10)

↓ The result looks like this ↓
