# Framingham 10-Year CHD Risk Calculator (Wilson 1998)

> Framingham 10-Year CHD Risk Calculator (Wilson 1998) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Computes the Wilson 1998 Framingham 10-year coronary heart disease (CHD) risk score using sex-specific point sheets for age, total cholesterol, HDL, JNC-V blood pressure, diabetes, and smoking status.

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 framingham-10-year-chd-risk-calculator-wilson-1998-36f7d764
```

Example prompt: Calculate the Wilson 1998 Framingham 10-year CHD risk for a 58-year-old male with a total cholesterol of 220 mg/dL, HDL of 42 mg/dL, systolic BP of 138 mmHg, diastolic BP of 88 mmHg, who has diabetes and is a current smoker.

## When to prefer this

Use this endpoint when you need the original Wilson 1998 Framingham CHD risk calculation specifically — not ATP-III 2001 adjustments or the 2013 ACC/AHA Pooled Cohort ASCVD equations. Ideal when a clinical workflow, guideline citation, or audit trail requires the published 1998 sex-specific point sheet arithmetic with JNC-V blood pressure categories. Prefer this over pooled-cohort ASCVD when the patient is aged 30-74 and the referencing guideline explicitly calls for Framingham 1998.

## Known failure modes

- Age outside 30-74 range returns an error (published derivation range only)
- Total cholesterol, HDL, SBP, or DBP outside clamped ranges returns a validation error
- Missing any required query parameter returns a 400-level error
- Invalid sex value (not 'male' or 'female') returns an error
- Non-boolean diabetes or smoker values cause schema validation failure

## How this service works

Wilson 1998 Framingham 10-year CHD from sex-specific total-cholesterol point sheets: age 30-74, TC, HDL, JNC-V blood pressure, diabetes, and smoking. Deterministic published arithmetic with citation. Not a statin order, not ATP-III 2001, not pooled-cohort ASCVD. magent does not measure lipids or BP.

## Output

Returns the Wilson 1998 Framingham sex-specific point total and corresponding 10-year CHD risk percentage based on published age/TC/HDL/BP/diabetes/smoking point assignments, with no additional modeling or extrapolation beyond the original published tables.
