While usually using native syntax rather than strings, somethign like that exists for most languages of any popularity (and many obscure ones), in the form of miniKanren implementations.
If you really want something that takes Prolog strings instead (and want the full power of prolog), then there are bindings to prolog interpreters from many languages, and also SWI-Prolog specifically provides a fairly straightforward JSON-based server mode "Machine Query Interface" that should be fairly simple to interface with any language.
