ASCOD Ischemic Stroke Phenotyping (Amarenco 2013)
x402
ASCOD Ischemic Stroke Phenotyping (Amarenco 2013) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15).
Computes the ASCOD phenotype string (e.g. A1-S0-C2-O0-D0) for ischemic stroke from five caller-assigned Amarenco 2013 grades covering atherosclerosis, small-vessel disease, cardiac pathology, other causes, and dissection.

How this service works
Amarenco 2013 ASCOD phenotyping of ischemic stroke from caller-assigned grades. A atherosclerosis, S small-vessel disease, C cardiac pathology, O other causes, D dissection. Each grade is 1 potentially causal, 2 causality uncertain, 3 unlikely causal but disease present, 0 absent, or 9 insufficient workup. Returns A1-S0-C2-O0-D0 style phenotype, not a summed score. magent does not read imaging. Not TOAST. Not CCS. Not a treatment. Not a medical device.
Output
Returns a formatted ASCOD phenotype string in the style A1-S0-C2-O0-D0, encoding each of the five etiologic categories (atherosclerosis, small-vessel disease, cardiac pathology, other causes, dissection) with their respective caller-assigned grades. Does not compute a summed score; each component grade is preserved independently.
Example use cases
Stroke workup phenotype encoding
“I've completed a stroke workup: atherosclerosis is grade 1 (potentially causal), small-vessel disease is grade 3 (unlikely causal but present), cardiac is grade 0 (absent), other causes are grade 9 (insufficient workup), and dissection is grade 0 (absent) — what is the ASCOD phenotype string?”
Uncertain cardiac etiology documentation
“For my ischemic stroke patient, atherosclerosis grade is 0, small-vessel is 0, cardiac is 2 (causality uncertain), other is 0, and dissection is 9 (insufficient workup) — can you give me the Amarenco 2013 ASCOD phenotype?”
Multi-etiology stroke classification
“My stroke patient has atherosclerosis grade 1, small-vessel grade 1, cardiac grade 0, other grade 0, and dissection grade 0 — encode that as an ASCOD phenotype using the Amarenco 2013 system.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/ascodWhen to prefer
Use this endpoint when you need to encode ischemic stroke etiology according to the Amarenco 2013 ASCOD phenotyping system and already have clinician-assigned grades for all five categories. Prefer this over TOAST or CCS classification tasks, as this endpoint is specifically ASCOD-only. It is a pure computation endpoint — it does not interpret imaging or produce treatment recommendations.
Side effects
- Missing any of the five required grade parameters returns a validation error
- Grade values outside the allowed set (0,1,2,3,9) are rejected
- Network or payment authorization failures return HTTP 402 or 5xx errors
