x402
RIFLE 2004 Acute Kidney Injury Classifier is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-13).
Classifies acute kidney injury (AKI) severity using the RIFLE 2004 framework (Bellomo Fig. 1) from baseline creatinine, current creatinine, and caller-assigned urine output category

How this service works
RIFLE 2004 (Bellomo Fig. 1) class from baseline and current creatinine in mg/dL and a caller-assigned urine-output category. Class is the worse of the two limbs; persistent ARF >4 weeks is Loss and >3 months is ESRD. magent does not assay creatinine, measure urine, or estimate baseline with MDRD. Not a medical device, not a diagnosis, not AKIN 2007, and not KDIGO 2012.
Output
Returns a RIFLE class label (Risk, Injury, Failure, Loss, or ESRD) representing the worse of the creatinine ratio limb and the urine output limb, along with the individual limb classifications. Loss is returned when persistent ARF exceeds 4 weeks; ESRD when kidney disease has persisted beyond 3 months, overriding all other classifications.
Example use cases
ICU AKI triage classification
“This ICU patient's baseline creatinine was 0.8 mg/dL and it's now 1.7 mg/dL; they've had oliguria for over 6 hours. No persistent loss or ESRD. What RIFLE class are they in?”
Persistent renal failure Loss staging
“A patient had complete kidney function loss for 5 weeks. Their baseline creatinine was 1.2 mg/dL, current is 3.6 mg/dL, and they have oliguria for 24 hours. Is this classified as RIFLE Loss?”
End-stage kidney disease ESRD flagging
“I have a patient with ESRD for over 4 months. Baseline creatinine 1.5 mg/dL, current 4.0 mg/dL, no oliguria criterion. Confirm their RIFLE class using the 2004 Bellomo criteria.”

Endpoint
GEThttps://api.magentlab.com/api/calc/rifleWhen to prefer
Use this endpoint when you need to apply the original Bellomo 2004 RIFLE classification specifically — not AKIN 2007 or KDIGO 2012. Ideal when you already have creatinine in mg/dL and a clinician-assigned urine output category. Do not use if you need automated urine measurement, creatinine assay, MDRD baseline estimation, or a different AKI staging framework.
Side effects
- Missing required query parameters returns a validation error
- Creatinine values outside the accepted range (0.1–20 mg/dL) are rejected
- Invalid urine_output enum value returns an error
- µmol/L creatinine values are not accepted and will produce incorrect results if passed without conversion
- Contradictory flags (e.g. both persistent_arf_gt_4_weeks and esrd_gt_3_months true) resolve to ESRD per the RIFLE hierarchy
