magent
Qureshi 1998 pediatric asthma score: five caller-assigned 1-3 domains — respiratory_rate (Table 1 age-banded ordinal, not raw breaths/min), oxygen_saturation, auscultation, retractions, and dyspnea. magent sums only (5-15) and returns Table 1 asthma_band mild 5-7, moderate 8-11, or severe 12-15. magent does not count breaths, measure SpO2, auscultate, or grade work of breathing. Not a diagnosis or treatment order. Not PRAM. Not Liu 2004. Not Westley croup.

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

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/pediatric_asthma_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.
