Golf Scoring API
Golf scoring and handicap maths as an API, computed locally and deterministically — the World Handicap System and Stableford numbers a golfer, club or scoring app works to. The handicap endpoint computes the course handicap from a handicap index: course handicap = index × (slope rating ÷ 113) + (course rating − par), rounded, so a 14.5 index on a 130-slope, 71.5-rated par-72 course plays off 16; it also applies the format allowance (e.g. 95 % for stroke play) to give the playing handicap. The stableford endpoint scores a hole on the standard scale: net par is 2 points, each stroke better adds one (birdie 3, eagle 4) and each worse subtracts one (bogey 1), with net double bogey or worse scoring 0, where the net score is the gross minus the strokes received on that hole. The net endpoint gives the round's net score — gross total minus the course handicap — against par. Everything is computed locally and deterministically, so it is instant and private. Ideal for golf, club-management, scoring and sports app developers, handicap and Stableford tools, and golf education. Pure local computation — no key, no third-party service, instant. Slope defaults to the neutral 113. Live, nothing stored. 3 compute endpoints. A scoring aid, not an official handicap record.
