I have the fen(arbitrary), I would like to get the completely opening names for the move list by passing the fen to the site. Are there any sites like this that are pretty exhaustive and free? It could simply return the last opening name as I could query it manually but this requires more work than I'd like to do.
Every site I have is some downloadable database or has an interface for searching through openings. I'd like something I could just get the names in json, html or some other text that correspond to the fen moves ordering. I'd rather not have to try and hack up some site to try and extract the info.
