Filtering TV series to only show series that are available for streaming on /discover/tv
I know that TV series don't have a region so i'm assuming that using 'with_release_type=4' won't work to only return items that have been released on Streaming.
Is there any way to get a filtered list of series that are available on streaming?

I don't know if I understood your question correctly, but...
I think maybe the solution is to use:
watch_region
use in conjunction with
with_watch_monetization_types
possible values are: [flatrate, free, ads, rent, buy] use in conjunction with watch_region, can be a comma (AND) or pipe (OR) separated query
or
with_watch_providers
use in conjunction with watch_region, can be a comma (AND) or pipe (OR) separated query

Thanks for the reply. I'll give with_watch_monetization_types a try.

I was thinking that using 'with_watch_providers' was an option, but I don't want to know if it's available on specific streaming services, I just want to know if it's available to stream on ANY streaming service. I guess, I could include all the streaming services in the with_watch_providers filter, but that seems like overkill because there are so many of them.
