0x2b6D4988Db4723E6908Db86Ab2b8dFBc51FC32C5The wallet the 402 directs payment to. Its whole payment record — every payer, every chain — is on the merchant page.

Provider
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.

Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

"description": "One-call drug situational awareness. Give a drug name (resolved to a canonical RxCUI via NIH RxNorm), or an exact rxcui or ndc you already hold, and get back: whether it is currently in FDA shortage, any open or recent FDA recalls, and FDA NDC-directory metadata (labeler, DEA schedule, pharmaceutical class, marketing status). Returns a resolved identity block plus hasCurrentShortage / hasOpenRecall booleans and one found/error block per source (shortages, ndc, recalls). Composition of NIH RxNorm + OpenFDA drug-shortages, NDC directory, and recall enforcement — all free, public-domain US government data; each source degrades independently. Point-in-time public records, not medical advice. Use for pharmacy/supply-chain triage, prescribing-support agents, and verifying a drug is real, scheduled, and available before acting.",

Using Roundhouse, look up the x402 service 2s 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=2s' 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://2s.io/api/medical/drug-status, 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.
