Creating pages with Write API

What are you trying to accomplish
I have some entity with dynamic pages, every entity has its own builder page. So when user visits the page of some entity, lets take entity-1, I will check is there any builder page for this entity via GET request with proper query params, if there is I will show the button with redirect to the Drag & Drop Headless CMS, but if there is no page, I will create the page with Write API. The issue is, after request for create page, the GET request is not returning newly created page, only after some time new page returns, approximately 1-1.5 minutes.
