FastballAPI vs BallDontLie
BallDontLie is a multi-sport API with plans sold per sport. FastballAPI is baseball only, with every pitch and plate appearance, per-book lines and run values.
BallDontLie is a sports data API with a free tier and paid plans sold per sport, with baseball among them. FastballAPI covers baseball only, with pitch-by-pitch and plate-appearance data, per-sportsbook lines and our RE24 run values and team ratings, over REST and an MCP server.
For one vendor across several sports, BallDontLie is built for that. For pitch-level baseball work, backtests against sportsbook lines, or an assistant that can answer baseball questions, FastballAPI is the narrower and deeper tool.
