# DOTS, IPF GL and Wilks calculator

`GET /api/tools/powerlifting-score`

## Request

- Base URL: `https://www.ironledger.app`
- URL: `https://www.ironledger.app/api/tools/powerlifting-score`
- Auth: none declared

Score a powerlifting total (or a bench press) against bodyweight with DOTS, IPF GL points and the original Wilks, using the coefficients the OpenPowerlifting rankings use.

Method: DOTS = total × 500 ÷ (a fourth-order polynomial in bodyweight); IPF GL = total × 100 ÷ (A − B·e^(−C·bodyweight)); Wilks = total × 500 ÷ (a fifth-order polynomial). Coefficients and bodyweight bounds as in OpenPowerlifting’s implementation.

## Query parameters

- `total` number, required: Total lifted (squat + bench + deadlift), or the bench press for event "bench".
- `bodyweight` number, required: Bodyweight in the chosen unit.
- `unit` 'kg' | 'lb': Weight unit for every load in and out: kg or lb.
- `sex` 'male' | 'female', required: The formulas have separate male and female coefficients.
- `equipment` 'raw' | 'equipped': For IPF GL: raw (classic) or equipped.
- `event` 'sbd' | 'bench': For IPF GL: sbd (full powerlifting total) or bench (bench press only).

## Response `200`
