Movies That Were Added On Streaming Services

Hey,

I’m building my own dataset about movies that were added later on streaming services (like Netflix, Hulu, Disney+, etc). I’ve found some useful datasets in Kaggle that include the date which a specific movie was added on Netflix, for example. I need to find the dates for other movies I have in my dataset, in all other streaming services which those movies were added on. Does anyone have any idea where can I find it? When I search a specific movie in Amazon Prime, for example, I don’t find the date in which it was added on their platform.

Thanks.
