Why not return items with the API?

Hi all! This problem. EMber sends a request but can't get an answer. As I understand it apparently is not permitted to access third-party applications. How to solve?

XMLHttpRequest cannot load http://my-api/items. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4200' is therefore not allowed access.
