Call before an agent runs npm install. Checks one npm package against the registry, OSV advisories, install scripts, typosquat and combosquat names and repository provenance, and flags hallucinated or slopsquatted names. Answers safe, caution, block or does_not_exist; every reason is sourced and labelled fact or heuristic.

Using Roundhouse, tell me whether this x402 merchant is worth paying: how many distinct
agents have paid it, how recently, and for what.

The /v0 API needs an API key (`authorization: Bearer rh_live_…`) on everything except
/v0/unified* and /v0/endpoints. Either pay over x402 (mint a personal key for $0.01 at
GET https://api.roundhouseai.io/v0/test/x402), or ask me for an organization key, which I create at
https://roundhouseai.io/dashboard/connections. If you have neither, ask before going further.

If you do not have Roundhouse tools or skills installed, read
https://roundhouseai.io/skill.md first — it is the whole procedure.
