How to get multiple frames from a movie via public api?

Question

JavaScript

There is a need to get some frames from the movie (Russian localization). The first thing that comes to mind is to use someone's API (for example, kinopoisk'a, imdb or tmdb) and take all the necessary information from there, incl. and frames.
However, upon closer examination, it turns out that film search does not (yet) have an official open API, nor does IMDB (and they seem to have so-so with the Russian language). The TMDB API has it, but the collection of "frames" (which they call 'backdrops') is not quite what you need, because people (and this collection is replenished by the site's community) shove both frames from the movie and logos there , and posters... Thus, it is not possible to automate the receipt of frames from the movie through tmdb's backdrops (for my task, it is important that these are frames from the movie,
Is there any way to solve this problem by using "someone's" database? Maybe there is some "not so sick" way to get frames from movie trailers? (We are talking about a web application, jap - JavaScript)
Any frames are needed (that is, no matter what), it is important that these are frames, and there are several of them (2-5 pieces).
