ACIP 2025 Table 2 catch-up minimum age and previous-dose interval. Eligible if age_months meets the printed minimum and weeks_since_previous_dose meets a printed interval (omit for dose 1). HepB dose 2 is 4 weeks. MMR/HepA/varicella dose 1 is 12 months. Not a vaccine order. magent does not immunize. Not routine age bars, Hib/PCV branching, HepB dose 3, or the 4-day grace period.

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/cdc_imm, 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.
