magent
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.

The payTo wallet does not resolve to a registered ERC-8004 agent. That is not a verdict on the service — most of the catalog is unregistered.

Using Roundhouse, look up the x402 service magent and tell me whether it is worth paying: what a call costs, whether the endpoint answered when last probed, and what its payment record actually shows. curl -s 'https://api.roundhouseai.io/v0/endpoints?q=magent' curl -s 'https://api.roundhouseai.io/v0/merchants/<the payTo wallet returned above>' Then call it: read the price from the live 402 at https://api.magentlab.com/api/calc/ascod, never from a cached figure, and pay with an x402 client. The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except /v0/unified* and /v0/endpoints. Mint a personal key for $0.01 at GET https://api.roundhouseai.io/v0/test/x402, or use an organization key from https://roundhouseai.io/dashboard/team. If you do not have Roundhouse tools or skills installed, read https://roundhouseai.io/skill.md first — it is the whole procedure.
