Manifold Markets is a Prediction market. Instead of real money or a cryptocurrency, they use “play money”.
The interesting thing is, they get good results even without using real money. It seems people still submit decent predictions even without a direct monetary incentive.
The market has an API that can be used without an API key for read-only data, and with an API key to submit predictions.
The API is documented here.
