How to get userbasic details from user profile url

How can I get Full name and profile photo from the use profile url i.e https://www.linkedin.com/in/sarthak-chauhan-737938115/ through linkedIn api

I have an application where user can enter their LinkedProfile url, using that url I need fetch only full name and profile photo.I should not required to make user login through the linkedIn account to fetch these details as these are public details and any linkedIn user can see these data by visiting to that user profile url that they shared with us.

I achieved the same for twitter through https://api.twitter.com/2/users/by/username/JoeBiden?user.fields=created_at,description,id,location,name,pinned_tweet_id,profile_image_url,protected,url,username,verified api

similar should be achievable using vanityname of linkedIn user that we can extract from user profile url

I think https://github.com/linkedin/linkedin.github.com/issues/12 issue is also related to similar requirement

LinkedIn API と、issue で説明されている profile URL または vanity-name flow から始め、その後、関連する issue #12 を確認します。full name と profile photo を user login なしで取得できるかを明らかにし、サポートされている動作または要件を文書化できれば完了です。
