Vehicle Intelligence for AI agents. Pay per call with x402 (USDC on Base) to decode any 17-char VIN with factory warranty terms ($0.01), read merged US (NHTSA) + Canada (Transport Canada) recalls ($0.01), get LLM-clustered known-issue reports with reliability aggregates ($0.05), and itemized used-car closing costs for all of Canada + 50 US states ($0.02). Free /v1/sample/* endpoints return every response shape. Informational data only — not a vehicle-history report.
Pay from $0.01 to $0.05 per request in USDC on Base, settled onchain via the x402 protocol, no signup, no API key needed.

risk clean
No deterministic risk flag. Risk fires only on an exact blocklist match, or a reserved-brand name with a mismatched verified payTo. Never from low uptime, a high price, or a model guess.
