x402 Migration Impact
Find out what a seller’s change breaks for one specific buyer. You declare which resources you call and what your wallet supports; changes to anything else are counted and set aside, because blocking your own upgrade on somebody else’s change is the mistake this prevents. Reports a resource you use becoming unpayable by you, moving to an unsupported version, changing payee, or rising in price. Nothing is paid.

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.

Using Roundhouse, look up the x402 service x402 Migration Impact 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=x402%20Migration%20Impact' 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://api.zfinia.com/x402/v1/x402-seller-migration-impact, 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. 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.
