check of link validity

Job ID: 31084262

Budget: $30 – $250 USD

Hello,
We need some tool for checking if some links (YouTube, TedX, LinkedIn Learning videos, etc.) are still work.
We have a lot of links to external sources (YouTube, TedX, LinkedIn Learning videos, etc.) and we need to regularly check if the links are still work or not.
We found several sources of information about this topic (bellow), but we are not programmers and don’t understand this field.
Our idea is that we prepare the list of external links and any SW tool will check it.
Can you help us?
Thank you,
Pavel
