Not sure what you mean. I suppose what I need is just to get the image url (api/files/6ceda0ff-a002-487f-be53-9f971e1c0230) without having to fetch the content
But you’re talking about images that are in a rich text field, right? You’re not talking about files which have been attached to the entity via the Files field…?
Not sure what you mean. The contents of any rich text field is available via the API
My point is that there is no single dedicated API to find/retrieve files which are embedded in the rich text. You need to retrieve the rich text field contents and then use the file API to get the file itself.
