# Magent D:A:D CKD Risk Score (Mocroft 2015 Table 2)

> Magent D:A:D CKD Risk Score (Mocroft 2015 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 2026-09-14).

Computes the Mocroft 2015 D:A:D full CKD risk score using integer point assignments from Table 2, returning a total score and low/medium/high risk band for HIV-positive patients with eGFR >60.

## 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 magent-d-a-d-ckd-risk-score-mocroft-2015-table-2-8b62c755
```

Example prompt: Calculate the D:A:D full CKD risk score (Mocroft 2015 Table 2) for a 52-year-old male HIV patient: no IVDU, no hepatitis C, eGFR 75 mL/min, nadir CD4 of 180 cells/mm³, hypertension present, no prior CVD, and no diabetes.

## When to prefer this

Use this endpoint when you need the Mocroft 2015 D:A:D full CKD risk score (Table 2 integer points) specifically — not the short score variant, not a Poisson probability model, and not a general eGFR calculator. Appropriate for HIV-positive patients with eGFR >60 mL/min where race is not an input. Choose this over generic kidney risk calculators when the clinical context is HIV-associated CKD risk stratification using the D:A:D cohort derivation.

## Known failure modes

- eGFR ≤60 provided — endpoint requires eGFR >60 (outside derivation population)
- age_years outside 16–120 integer range — validation error
- nadir_cd4_cells_mm3 outside 0–3000 integer range — validation error
- egfr_ml_min outside 0.1–250 range — validation error
- Missing required query parameters (any of the nine) — 400 bad request
- sex enum value not 'male' or 'female' — validation error
- Payment not provided or insufficient (x402) — 402 Payment Required

## How this service works

Mocroft 2015 D:A:D full CKD risk score (Table 2 integer points only): IDU, hepatitis C, age, caller-assigned eGFR >60, sex, nadir CD4, hypertension, prior CVD, and diabetes. Bands low <0, medium 0–4, high ≥5. Not the short score, not the Poisson probability model, not NNTH, and not an ART start order. Race is not an input.

## Output

Returns the summed integer point total from Mocroft 2015 Table 2 across all nine risk factors, plus a categorical risk band: low (score <0), medium (score 0–4), or high (score ≥5). Does not return a Poisson probability, NNTH, short score variant, or ART recommendation.
