...no. Kinda.
A lot of agents handle YA/MG fantasy, some do non-traditional (non epic/high) fantasy, and some only handle Epic/high.
Sword and Sorcery is pretty close to High fantasy, but more focused on the character. (my genre Heroic fantasy is more focused still).
No story is purely "Fantasy" but the story itself holds a flavor of action/drama/mystery, so that's just expected.
Market your book as Sword and Sorcery Fantasy. The mystery would have to be unveiled while reading.
I can't say anything about the lack of interest, any publisher/agent will grab a good story regardless of the genre's popularity of the current time.
