# CAROC 2010 10-Year Fracture Risk Calculator

> CAROC 2010 10-Year Fracture Risk Calculator 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 CAROC 2010 10-year major osteoporotic fracture (MOF) risk category (low/moderate/high) from age, sex, femoral-neck T-score, and clinical modifier flags.

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 caroc-2010-10-year-fracture-risk-calculator-4539546f
```

Example prompt: What's the CAROC 2010 fracture risk category for a 68-year-old female with a femoral-neck T-score of -2.5, who had a fragility fracture after age 40 but no hip or spine fracture, no multiple fragility fractures, and has been on prolonged glucocorticoids?

## When to prefer this

Use this endpoint when you need to programmatically apply the published CAROC 2010 Canadian fracture risk classification table to a patient's age, sex, and femoral-neck T-score with clinical modifier flags. Prefer it over FRAX-based tools when the clinical workflow specifically calls for CAROC 2010 categories and Canadian guideline alignment. It is not a substitute for FRAX probability calculations or clinical judgment, and does not perform DXA or medication ordering.

## Known failure modes

- Age outside 50–89 range returns a validation error rejecting the input
- Invalid sex value (not 'female' or 'male') causes a rejection
- T-score outside -6.0 to 4.0 range is rejected
- Missing required query parameters return an error
- Caller-supplied boolean flags not interpretable cause malformed request errors

## How this service works

CAROC 2010 10-year MOF category from age, sex, femoral-neck T-score, and fragility or glucocorticoid flags. Basal low/moderate/high from printed T-score bands; hip or spine fragility or multiple fractures is high; fracture after 40 plus steroids is high; either flag alone bumps one class. Labels <10%, 10-20%, >20%. Not FRAX or a drug order. Not a medical device.

## Output

Returns the CAROC 2010 10-year major osteoporotic fracture risk category: low (<10%), moderate (10–20%), or high (>20%), derived from the printed T-score band table adjusted by clinical modifier flags (hip/spine fragility, multiple fractures, fragility fracture after 40, prolonged glucocorticoids).
