# ADA Diabetes Risk Score (Bang 2009 Table 2)

> ADA Diabetes Risk Score (Bang 2009 Table 2) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).

Computes the Bang 2009 Table 2 undiagnosed diabetes screening score from age, sex, BMI, family history, hypertension, and physical activity, returning the total score and a high-risk flag (score ≥ 5).

## 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 ada-diabetes-risk-score-bang-2009-table-2-a2bb60d8
```

Example prompt: Can you run the Bang 2009 ADA diabetes screening score for a 54-year-old male with a BMI of 31.2, a family history of diabetes, hypertension, and who is not physically active?

## When to prefer this

Choose this endpoint when you need a validated, well-documented implementation of the Bang 2009 Table 2 diabetes screening score specifically using BMI (not waist circumference) as the obesity criterion. It is the right choice for clinical decision-support tools, pre-visit risk triage, or population-level screening pipelines that need a reproducible score with a clear high-risk threshold. Prefer alternatives if you need waist-based obesity criteria (ARIC/CHS appendix methodology), an HbA1c-based risk tool, or actual diabetes diagnosis logic.

## Known failure modes

- Missing required query parameters (age, sex, bmi_kg_m2, family_history_diabetes, hypertension, physically_active) returns a 400 validation error
- Age outside valid range 20–120 or BMI outside 10–80 rejected with validation error
- Invalid enum value for sex (not 'male' or 'female') returns error
- Payment not included or insufficient USDC balance returns 402 Payment Required
- Network timeout or server error returns 5xx; retry with same parameters is safe since endpoint is idempotent

## How this service works

Bang 2009 Table 2 development screening score for undiagnosed diabetes. Age (<40 → 0, 40–49 → 1, 50–59 → 2, ≥60 → 3); male 1; family history of diabetes 1; hypertension 1; BMI (≥40 extremely obese 3; 30–<40 obese 2; 25–<30 overweight 1; else 0); physically active −1. Returns score and high_risk (true iff score ≥ 5). BMI-only, no waist. Not Appendix ARIC/CHS, not a diagnosis.

## Output

Returns a numeric total screening score (which can range from −1 to 10) calculated by summing age-band points (0–3), sex points (male = 1), family history points (1 if true), hypertension points (1 if true), BMI-band points (0–3), and physical activity deduction (−1 if active). Also returns a boolean field high_risk that is true when the total score is 5 or higher, indicating elevated risk for undiagnosed diabetes per Bang 2009 Table 2.
