Searches the FDA enforcement database for drug recalls matching a product name, company or date range and returns each with the classification leading: class one means use can cause serious harm or death, class three means it will not, and a recall for a wrong label colour and one for contamination share only the word. The class is therefore returned with its meaning spelled out rather than as a bare code.
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.

The class is therefore returned with its meaning spelled out rather than as a bare code. Each record carries the reason for the recall as reported, the recalling firm, the initiation and report dates, the status — ongoing, completed or terminated — the distribution pattern, and the quantity affected. Results are grouped by class so the serious ones are visible without reading the list. An ongoing class one recall is flagged prominently. The database covers the United States only and reports with a lag of weeks between a recall starting and appearing here, both of which are stated, because an empty result for a recent event usually means not yet published rather than nothing happened.",

Hand this page to an agent
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. 18 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/drug-recall, 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.
