THRIVE Stroke Outcome Score Calculator
x402
THRIVE Stroke Outcome 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).
Computes the THRIVE (Totaled Health Risks in Vascular Events) score from age, NIHSS, and chronic disease factors to estimate 90-day functional outcome and mortality risk after ischemic stroke.

How this service works
Deterministic published-formula arithmetic plus ICD-10-CM, RxNorm, and LOINC. Pay in USDC on Base via x402.
Output
Returns the computed THRIVE total score (0–9), the corresponding risk band (low 0–2, moderate 3–5, high 6–9), and published 90-day outcome statistics including the probability of achieving modified Rankin Scale 0–2 (functional independence) and 90-day mortality, based on the Flint 2010 AJNR derivation cohort.
Example use cases
Acute stroke triage in emergency department
“I have a 68-year-old stroke patient with a NIHSS of 12, known hypertension and diabetes, no atrial fibrillation — can you run the THRIVE score and tell me what risk band they fall into?”
Stroke registry outcome prediction
“For a 55-year-old patient with NIHSS of 8, no hypertension, no diabetes, and no atrial fibrillation, what does the THRIVE score predict for their 90-day functional recovery and mortality?”
Clinical documentation for high-risk elderly stroke patient
“My patient is 82 years old, NIHSS is 23, has hypertension, diabetes, and atrial fibrillation — compute their THRIVE score and give me the published 90-day mRS 0-2 and mortality percentages.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/thrive?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a validated, published clinical score (Flint 2010 AJNR) for 90-day stroke outcome stratification based on age, NIHSS, and chronic comorbidities. Prefer it over generic LLM-based prognosis when you need reproducible, citation-backed risk bands with published outcome percentages. Note: this is not a treatment recommendation and does not replace clinician judgment or NIHSS examination.
Side effects
- Missing required parameters (age, nihss, hypertension, diabetes, atrial_fibrillation) returns validation error
- Age outside 18–120 range rejected
- NIHSS outside 0–42 range rejected
- Boolean fields supplied as non-boolean strings may cause parsing errors
- Payment failure (x402) if USDC not available or insufficient balance
