Vehicle Intelligence for AI agents. Pay per call with x402 (USDC on Base) to decode any 17-char VIN with its original factory new-vehicle warranty terms folded in ($0.01), read MERGED US (NHTSA) + Canada (Transport Canada) recalls with the full decoded VIN folded in ($0.01), and get LLM-clustered known-issue reports that bundle a reliability-aggregates block and the full decode (every issue cites verified ODI complaint numbers; $0.05), plus itemized used-car closing costs for all of Canada + all 50 US states & DC via /v1/purchase-costs?country=CA|US ($0.02). FREE /v1/sample/* endpoints return every response shape for one fixed sample vehicle (2013 Ford F-150, VIN 1FTFW1ET5DFC10312) so you can try before you pay. Every JSON object response carries a legal `disclaimer` field. Informational data only — not professional/purchase advice, and NOT a vehicle-history report (no liens/accidents/odometer). Contains information licensed under the Open Government Licence – Canada.

Skills

• Normalized NHTSA vPIC VIN decode
  Paid ($0.01 USDC via x402). Decodes a 17-char VIN through NHTSA vPIC and returns the normalized decoded vehicle (make/model/year/engine/body/…) with fetch provenance, PLUS a `warranty` block giving the ORIGINAL factory new-vehicle warranty terms (basic/powertrain/corrosion/roadside/EV-battery) keyed off the decoded make + model-year. Warranty terms are the manufacturer's original coverage as sold — NOT warranty-remaining, and NOT extended-warranty campaigns, recalls, or emissions warranties. The cheapest call when you only need the decode — the same `vehicle` object is also folded into /v1/recalls and /v1/known-issues. Compute-first / settle-after. Free fixed-sample preview of this exact shape: GET /v1/sample/decode.

• Merged US (NHTSA) + Canada (Transport Canada) recalls + full decoded vehicle
  Paid ($0.01 USDC via x402). Decodes the VIN and returns the FULL decoded vehicle (the same payload as /v1/decode is folded in here), then merges NHTSA (US) and Transport Canada (CA) recalls into one response — the only API combining both. 24h cache per source; stale served on failure. Canadian detail capped at the 25 most-recent recalls. OGL–Canada attribution. Compute-first / settle-after. Free fixed-sample preview of this exact shape: GET /v1/sample/recalls.

• LLM-clustered named failure modes with verified ODI citations + reliability block + full decode
  Paid ($0.05 USDC via x402). Clusters NHTSA owner complaints into named failure modes; EVERY cited ODI number is programmatically validated against the input complaint set (hallucination-gated) and every issue carries ≥2 verified citations. Severity signals per issue are summed from the CITED complaints only. The response also bundles a `reliability` aggregates block (top components, severity signals, US/Canada recall counts incl. Canadian units affected — reliability was merged into known-issues on 2026-07-07), the full decoded `vehicle` (same payload as /v1/decode), and `complaintsAnalyzed`, the size of the recent-weighted stratified sample the LLM actually saw (vs `complaintCount`, the total). Refuses UNCHARGED below 15 complaints (returns 200 status:insufficient_data) — but still returns the decode + reliability block for free. 90-day cache. Compute-first / settle-after. Free fixed-sample preview of this exact shape: GET /v1/sample/known-issues.

• Itemized US + Canada used-vehicle closing costs (country=CA|US)
  Paid ($0.02 USDC via x402). Government-imposed closing costs of buying a used passenger vehicle, unified across both countries via `country=CA|US`. CA: any of Canada's 10 provinces + 3 territories (BC, AB, SK, MB, ON, QC, NB, NS, PE, NL, YT, NT, NU) — provincial/territorial sales tax (PST/RST/QST/HST or GST-only) plus transfer/registration/plate fees and inspection; tax is flat on the whole price at the highest bracket whose threshold the price meets (BC private 12% → 15% ≥ $125,000 → 20% ≥ $150,000); Alberta + the three territories levy no private-sale tax; dealer sales add 5% GST except in HST provinces (ON/NB/NS/PE/NL). US: any of the 50 states or DC — sales/use/excise tax, title, first-year registration, inspection, and (for dealer sales) a dealer documentation fee; special regimes handled automatically (DC tiered title-excise range, IL flat RUT-50 private-party table, SC 5% IMF capped at $500, and AK/AZ/HI/MT/NV/NH/OR no private-party sales tax). Each line carries a source URL and confidence. Figures verified 2026-07-04. Compute-first / settle-after. Free fixed-sample preview of this exact shape: GET /v1/sample/purchase-costs.
