med.halowerk.com
Resolves two products to their RxNorm concepts and compares what the register declares about each: the active ingredient set, the strength per ingredient, the dose form and the route of administration. Every difference is listed individually rather than collapsed into a verdict, and matching ingredients with differing strengths are reported as such rather than as a match.
The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.
Asset 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913
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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Every difference is listed individually rather than collapsed into a verdict, and matching ingredients with differing strengths are reported as such rather than as a match. The service explicitly does not decide substitutability, and that is a statement about pharmacology rather than caution: bioequivalence depends on formulation, not on the ingredient list, so two tablets with the same substance at the same strength can differ in release profile — extended release against immediate release is the obvious case and there are subtler ones. What is returned is the comparison of declared attributes and the list of differences; the substitution decision requires bioequivalence data and belongs to a pharmacist. Where a product resolves only approximately the score is returned, because a near match on a drug name is not a match.",

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. 23 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

Using Roundhouse, look up the x402 service med.halowerk.com 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=med.halowerk.com' 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://med.halowerk.com/v1/ingredient-equivalence, 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.
