The API just provide data. The way you display them is up to your application.

does API provide the episode release date and episode number?

I can see only episode number but not the release date in references - https://developer.themoviedb.org/reference/tv-episode-details

air_date would be the field you’re looking for.

Sorry for posting this question in the other way but my developer still can't understand one thing in the API doc.

Is there any API calls showing tv shows list that includes episode number and release date?

With the Id of a TV show, you need to call GetTVDetails to get the number of seasons and episodes, and then you can call GetSeasonDetails or GetEpisodeDetails to get the required informations.

my developer tells me that to display the episode release date in the category where the TV shows list has 100+ titles we need to call the API for 100+ times. That can cause to bad performance of app, and in almost case, TMDB will block our API call request because of spam calling. Is it true?

This is the same as if you want to display the title of all the episodes.

But, normally, you display only the list of the shows and you fetch and display data about the episodes only when the user select a specific show.

That can cause to bad performance of app,

The first result, if you directly display all the episodes data, without even talking of performance, will be an unreadable display due to the amount of data.
