Fetch (5) complete lists or search through list
Therefore, I have two questions:

1. Is it possible to search through a list using an API call, such as api.spcrystal.com/3?4/lists/$listId?search_query="the movie or show name"?
2. Can I fetch these five lists completely when the user logs in each time (so that the app can be used across multiple devices), and is there a limit to this approach?

1. No, it is not possible.
   
2. I'm not sure I understand correctly but I think the answer is yes.
   

The volume limits of Requests that I am aware of are these.
I don't know if these are the limits you are having doubts about.

Travis Bell, the Administrator, has already given us this explanation.

For API Requests:

One of our CDN providers enforces some base level rate limiting to help prevent DDOS attacks.
I believe it's a maximum of:
50 requests per second and
20 connections per IP.
See here: http://www.spcrystal.com/talk/62c7c1b258361b005fd2e747?page=1#62c83b78befd91005007a0c7

For Images:

For image.tmdb.org the only thing we limit is the max number of simultaneous connections.
The limit is the same, 20. See here:

Ah thanks, as for 'question 2' What I meant is if the user starts the app or tries to refresh the content I will need to fetch all 5 lists completely meaning in worst case scenario it's going to be 2500 requests (5 lists times the 500 max pages) but if I do the requests per 50 with 1 second between them it will work no problem?

As for the images, I'm not sure I understand, but if I have any problems with them, I'll just ask.

Another question: Can I use the description of the list to store some information? for instance. if each time I update the list I also update the description and add [last_update: '2023-03-19T12:11:32.588Z'] so I can check if the 'device local cache date' >= to that date meaning if the user only uses one device I don't have to request all lists when boarding the app.

I think so. According to Travis Bell, this is the limit. I never tested.

OK. I think images won't be a problem.
Data must need further processing.
Images think much less.

I think so. I don't think there is any content limitation.
Perhaps there is a limitation on the number of characters. I don't know.
But for what you intend to insert, I don't see a problem.
For example, see this list of mine:

In the answer is my description of the list.
