It's all in-house, available in 84 countries and supports thousands of streaming services. There is an API but it's mostly available to larger partners: https://www.justwatch.com/us/JustWatch-Streaming-API

You need a way to change language on your webpage. Many, if not most visitors from UAE cannot read Arabic, and most AE websites will in my experience default to English. But justwatch has seemingly no way to change from Arabic when visiting from UAE.

If I go to justwaych.com/us, it changes to English, but now I suppose I am browsing US availability. Again, this isn't written anywhere, so I don't know if what I'm browsing or searching is available.

You can change language and country independently from each other. Just click on the Account settings in the top left/right corner (depending on locale) and change it there.

When not signed in, the button just says "Sign In", which is not something anyone would look for a language change option - doubly so if the "Sign In" in is in a foreign language. There is plenty of space to add a globe icon or something like it directly on the page there.

Can I use it to find foreign films? Right now my best option is yts torrent tracker[0] but there's a ton of hindi films which I don't really like.

Would be cool to find all non-english films from europe and america.

I love JustWatch, it's the first place I go when I discuss any show with friends, family, kids, anyone.

My kids now, before we buy an episode, say "Dad check on JustWatch if we can stream it for free anywhere"

Do you have public examples of others that use your API? I have a few ideas that can be used but no time at all to build things :)

One public example would be TMDb (The metadata source that also OPs project is using): https://www.themoviedb.org/movie/568124-encanto/watch

Letterboxd uses their API. I track my watchlist on Letterboxd and can filter movies available to stream in my subscriber services thanks to their use of the JustWatch API.

Not sure it matters much, but I had been using justwatch often. It stopped working for me a while back: search just wouldn't do anything.

I just cleared all my cookies and now it works again.

Not sure how big the problem is, but at least for me, your website seemed to be choking on its own cookies.

JustWatch is great.

There's a trend in my country (Italy) where old movies are being remastered in HD but not published on Blu-ray. Instead, they're only made available on one out of a half dozen or so streaming services. JustWatch helps me immensely to spot new releases like that!

What a great website. I use it all the time. Thank you!
