magent
Rost 2008 FUNC score (0-11) after primary ICH from caller-assigned volume, age, location (lobar/deep/infratentorial), GCS, and pre-ICH cognitive impairment. Volume <30 mL scores 4, 30-60 scores 2, >60 scores 0; age <70 scores 2, 70-79 scores 1, >=80 scores 0; lobar 2, deep 1, infratentorial 0; GCS >=9 scores 2, <=8 scores 0; cognitive impairment absent scores 1. Companion to the Hemphill ICH Score, not a replacement. Not a diagnosis or withdrawal-of-care protocol. magent does not read CT.

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.

Copy the prompt and paste it into Claude, an MCP client or your own agent — it will vet this service and call it over the free read API. No key, no account.
GET api.roundhouseai.io/v0/endpoints
This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 15 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

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/func_score, 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.
