Child-Pugh Cirrhosis Severity Score Calculator
x402
Child-Pugh Cirrhosis Severity Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-10-10).
Calculates the Child-Pugh (Child-Turcotte-Pugh) score and class (A/B/C) for cirrhosis severity from bilirubin, albumin, INR, encephalopathy grade, and ascites.

How this service works
Deterministic published-formula arithmetic plus ICD-10-CM, RxNorm, and LOINC. Pay in USDC on Base via x402.
Output
Returns a numeric Child-Pugh total score (5–15), Child-Pugh class (A, B, or C), individual sub-scores for each of the five parameters, and a citation to the published scoring criteria.
Example use cases
Pre-procedure liver risk stratification
“My patient with cirrhosis needs a cholecystectomy — can you calculate their Child-Pugh score? Bilirubin is 1.8 mg/dL, albumin 3.6 g/dL, INR 1.4, no encephalopathy, and no ascites.”
Hepatology chart review automation
“For my hepatology dashboard, calculate the Child-Pugh class for a patient whose labs show bilirubin 3.5 mg/dL, albumin 2.6 g/dL, INR 2.5, grade 3-4 encephalopathy, and moderate ascites.”
Unit conversion and scoring from SI labs
“I have a cirrhosis patient with bilirubin 51 µmol/L, albumin 28 g/L, INR 1.8, no encephalopathy, and slight ascites — what's their Child-Pugh score and class?”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/child_pugh?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a fast, deterministic, evidence-based Child-Pugh score computed from explicit lab values and clinician-assigned clinical parameters. Prefer this over manual calculation to avoid arithmetic errors, or when building clinical decision support tools, hepatology dashboards, or automated chart review pipelines. This is not a transplant listing protocol and requires that encephalopathy and ascites grades be assigned by the calling clinician.
Side effects
- Missing required parameters (INR, encephalopathy, or ascites) returns a 400 error
- Bilirubin or albumin values outside valid physiological ranges may return an error or unexpected scoring
- Providing both bilirubin_mg_dl and bilirubin_umol_l may cause ambiguity — use only one
- Invalid encephalopathy or ascites enum values (e.g. typos) cause validation failure
- Payment not included or insufficient (x402) results in 402 Payment Required
