How this service works
World Handicap System index from your last 3 to 20 rounds (best differentials), plus course handicap for a course.
Output
Returns the calculated WHS handicap index (rounded), course handicap (rounded and unrounded), the list of differentials computed from input scores, the lowest differentials used in the calculation, the number of scores used, any adjustments applied, a summary explanation, and optional reasons or warnings about the calculation.
Example use cases
Calculate handicap index from recent scores
“I played 10 rounds recently and shot 82, 86, 79, 88, 84, 91, 80, 85, 83, 87 — all on a course with a rating of 70.8 and slope of 124. Can you calculate my WHS handicap index from those?”
Convert handicap index to course handicap
“My handicap differentials from my last 6 rounds are 12.3, 14.1, 11.8, 13.5, 15.2, 12.9. What's my WHS index, and what would my course handicap be for a course with a rating of 72.4, slope of 135, and par 72?”
Check playing handicap for a weekend round
“I've got score differentials of 8.4, 9.1, 10.2, 7.8, 9.6 from my last five rounds. Can you figure out my handicap index and then tell me how many strokes I'd get at a course with slope 118, rating 69.5, and par 70?”
Technical details
Endpoint
GEThttps://sports-calc.x402tookit.com/golf-handicap?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need an official World Handicap System handicap index computation from raw scores or pre-computed differentials, especially when you also need to convert that index to a course-specific playing handicap. Prefer this over manual calculation or generic sports APIs when WHS-compliant logic (best differential selection, adjustments, rounding) is required.
Side effects
- Missing required scores or differentials — returns error if neither scores nor differentials are provided
- Insufficient rounds — fewer than 3 scores/differentials may not produce a valid index
- Invalid slope rating outside 55–155 range — rejected or produces unexpected results
- Missing courseRating when scores are provided — differentials cannot be computed without it
- Mismatched parameter combinations — providing differentials alongside courseRating/slopeRating may be ignored or cause confusion
