Is there an online chess evaluation engine with a REST API? Is there an online chess evaluation engine with a REST API? I'd like to be able to send a game or position (with castling ability presumably) to a simple REST API and get back the positional evaluation from a reasonably strong engine.
It is pointless to have a rest API for random position evals which have to be precomputed for near-instant response. In that case you might as well ask for an opening book. There are a few sites that with opening book querying tools, which are pretty close.
