Baseball Stats API

healthy 4,180 Subscribers

Baseball sabermetrics as an API, computed locally and deterministically — turn raw counting numbers into the rate stats that actually rank players. The batting endpoint takes at-bats, hits, doubles, triples, home runs, walks, hit-by-pitch and sacrifice flies and returns the batting average (H/AB), on-base percentage ((H+BB+HBP)/(AB+BB+HBP+SF)), slugging percentage (total bases/AB), OPS (on-base plus slugging), isolated power (SLG−AVG) and, when strikeouts are supplied, BABIP — a classic .300/.366/.530 line comes straight out. The pitching endpoint takes innings pitched, earned runs, hits, walks, strikeouts and home runs and returns the earned run average (9·ER/IP), WHIP ((BB+H)/IP), strikeouts and walks per nine innings, the strikeout-to-walk ratio and FIP, the fielding-independent pitching estimator (13·HR + 3·(BB+HBP) − 2·K)/IP + constant. Innings pitched is a true decimal, with an exact "outs" input for the 6.1/6.2 box-score convention. Everything is computed locally and deterministically, so it is instant and private. Ideal for fantasy-baseball, sports-analytics, sabermetrics and box-score app developers, scouting and stat-line tools, and teaching material. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 2 compute endpoints. This computes the stats from your numbers; for live scores, standings, teams and players use a sports-data API.
