Without being able to run indexing servers, I am limited to what I can do with search. The public API servers, I'm not well suited to this, but I'll speak to some people and see if there are any options i've missed.
At some point, it would be good to run a eureka server for data such as this, but the project really needs to generate income to be able to sustain that.
