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.

Answers: the position-9 check digit verdict, the WMI's recorded manufacturer, make, vehicle type and registered country, and the position-10 model-year code as a candidate set from 49 CFR 565.15(d)(1) Table VII and 49 CFR 565.25(d)(1) Table XIII, narrowed to a single year only for passenger cars, the one class whose disambiguation rule does not depend on a gross vehicle weight rating this snapshot does not carry. The check digit refuses MOST transcription errors, not all: 49 CFR 565.15(c) Table III assigns several letters the same value, so substitutions and some transpositions within a value class are undetectable. Does NOT answer engine, body, series, trim, restraints, plant, weight class, or any per-manufacturer VIN pattern — those are not bundled. Does NOT assert that a vehicle exists, is registered, or is on the road. A VIN lawfully exempt from 49 CFR 565.15 under 49 CFR 565.2(a)(1) may be refused as malformed when it is not. Rows carrying characters this bundle cannot represent, and rows for which vPIC records no country at all, were refused and counted rather than repaired, which drops non-US manufacturers disproportionately, so both a refusal and an absent country skew non-US. A WMI the register maps to more than one make is refused rather than carried as a derived, comma-joined value, which is 511 of those refusals. Where one WMI carries more than one vehicle type — none in this vintage — the reported vehicle type is the first row in bundle order, a deterministic but arbitrary choice, and the model year stays a candidate set, never narrowed. These same facts are published free and unauthenticated by NHTSA and are fresher there; what this route sells is a digest-pinned, replayable, offline answer with a stated vintage and a stated coverage. A WMI missing here is missing from THIS snapshot only, never from the vPIC register; growing coverage is a bigger snapshot and a redeploy, never a live fetch.",

Using Roundhouse, look up the x402 service Alien Probe 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=Alien%20Probe' 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://lookups.alienprobe.ai/v1/lookup/vin/:vin, 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.
