paket.halowerk.com
Takes the names your organisation publishes internally and checks each against the public registry of the same ecosystem. Three findings, kept apart because they call for different actions. Name is free: nobody has taken it, the door is open but unattended, and the answer is to reserve the name yourself. Name is taken and old: probably an unrelated project that happens to share the name, worth confirming but rarely urgent.

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.

Three findings, kept apart because they call for different actions. Name is free: nobody has taken it, the door is open but unattended, and the answer is to reserve the name yourself. Name is taken and old: probably an unrelated project that happens to share the name, worth confirming but rarely urgent. Name is taken and appeared recently, especially after your internal package existed: the pattern of an actual attack, and the response gives the first publication date so that judgement can be made. On top of that, when you supply your internal version, the public version is compared against it, because a resolver that prefers the highest version will pick the public package the moment it climbs above yours — that comparison, not mere existence, is what decides the outcome in most build systems. Scope prefixes are honoured as they are given: an npm name under an organisation scope is a different name from the unscoped one, and treating them alike would produce false alarms on every package you own.",

Using Roundhouse, look up the x402 service paket.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=paket.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://paket.halowerk.com/v1/dependency-confusion, 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.
