0x2880EdfFF13100677Bf97A3CBdF3Bc34771C4E5EThe 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.
Live 402 challenge
Captured by the enrichment pass, not read just now. Prices can change — always read the 402 the endpoint answers with.

Versions are ordered by semantic version, not alphabetically and not in registry order, so 1.10.0 sorts after 1.9.0 — the mistake that quietly breaks naive comparisons. For each version you get the publication timestamp, whether it is the registry default, whether it is deprecated and the deprecation reason as the registry states it. On top of the list the response names the newest version, the newest stable version ignoring pre-releases, the oldest, the total count, how many are deprecated and the span in days between first and last publication. Versions whose string does not parse as semantic version are kept and flagged rather than dropped, because Maven and Go both carry shapes that strict parsers reject; the confidence value falls when that happens. Licence information from the registries is machine-derived and does not replace a legal review.",

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.

This endpoint's own trailing-30-day call count, as published by the upstream catalog and snapshotted daily. 30 snapshots so far. Verified volume counts only settlements with an on-chain EIP-3009 marker.

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/package-versions, 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.
