# Sports Calculators – Basketball Efficiency Stats

> Sports Calculators – Basketball Efficiency Stats is a paid API for AI agents from sports-calc.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-21).

Computes basketball efficiency metrics (eFG%, true shooting %, points, per-36 rates, assist-to-turnover ratio) from raw box-score numbers.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability sports-calculators-basketball-efficiency-stats-97f62813
```

Example prompt: Calculate the basketball efficiency stats for a player who went 8-for-18 from the field, 3-for-5 from three, and 6-for-8 from the free throw line, with 7 assists, 3 turnovers, 9 rebounds, in 34 minutes — give me their eFG%, true shooting %, and per-36 rates.

## When to prefer this

Choose this endpoint when you need to compute derived basketball efficiency metrics from raw counting stats in a single call without maintaining a database. It is ideal for real-time stat lookups, scouting tools, fantasy sports apps, and post-game analysis where you already have box-score numbers and need advanced metrics like eFG%, TS%, and per-36 rates instantly.

## Known failure modes

- Missing required fields (fg, fga) returns an error
- fga = 0 causes division-by-zero, likely returning null or error for shooting percentages
- Negative integer inputs may return unexpected results or errors
- fta = 0 with ft > 0 is inconsistent and may degrade output
- minutes = 0 causes per-36 rates to be null or undefined

## How this service works

Basketball efficiency from box-score numbers: eFG%, true shooting %, points, per-36 rates and assist-to-turnover ratio.

## Output

Returns a JSON object with computed basketball efficiency metrics including effective FG% (effectiveFgPct), true shooting % (trueShootingPct), raw FG% (fgPct), FT% (ftPct), free throw rate, assist-to-turnover ratio, total points, points per shooting possession, and per-36 minute rates for points, assists, rebounds, and turnovers. May include a summary, verdict, disclaimer, and a timestamp (asOf).
