# Cadarette 2000 ORAI Osteoporosis Risk Assessment

> Cadarette 2000 ORAI Osteoporosis Risk Assessment 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 Cadarette 2000 Osteoporosis Risk Assessment Instrument (ORAI) score from age, weight, and current estrogen use to identify women who should be referred for bone densitometry.

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 cadarette-2000-orai-osteoporosis-risk-assessment-28d4a6b6
```

Example prompt: What's the ORAI osteoporosis risk score for a 68-year-old woman who weighs 57 kg and is not currently taking estrogen — does she meet the threshold to be referred for bone densitometry?

## When to prefer this

Use this endpoint when you need a fast, validated implementation of the specific Cadarette 2000 ORAI instrument (not OSTA, not FRAX) to screen women aged 45+ for osteoporosis risk and decide on bone densitometry referral. Prefer it over manual scoring tables when integrating into an automated clinical workflow or EHR decision-support agent.

## Known failure modes

- Age outside 45–120 range returns a validation error
- Neither weight_kg nor weight_lb provided returns an error
- Both weight inputs simultaneously supplied may cause ambiguity
- Boolean parsing failure if current_estrogen is not a proper boolean
- Weight outside 1–500 kg (or 2–1100 lb) range rejected

## How this service works

Cadarette 2000 Osteoporosis Risk Assessment Instrument (ORAI). Additive Table 4 score: age ≥75 → 15, 65–74 → 9, 55–64 → 5, 45–54 → 0; weight <60 kg → 9, 60–69 kg → 3, ≥70 kg → 0; current estrogen no → 2, yes → 0. Max 26. Score ≥9 would be selected for bone densitometry. Age 45–120; weight_kg or weight_lb. Not a medical device, not OSTA, not FRAX, not a DXA order.

## Output

Returns the ORAI additive score (0–26) computed from the three Cadarette 2000 Table 4 inputs: age band (0/5/9/15), weight band (0/3/9), and estrogen status (0/2). A score ≥9 indicates the patient should be selected for bone densitometry.
