Canadian-market vehicle dimensions and weights from NHTSA vPIC's Canadian Vehicle Specifications dataset. Pass year + make (required) and optional model to narrow. Returns one entry per matching trim with labeled dimensions — overall length/width/height (cm), wheelbase (cm), curb weight (kg), front/rear track width, interior head/leg/shoulder/hip room, and weight distribution — plus the full raw spec map. Authoritative measured specs (the SAE dimension codes), not estimates. Keyless, public-domain; covers model years 1971+.
/api/vehicle/canadian-specsPAYMENT-SIGNATURE.The canadian specs API is a pay-per-call vehicle endpoint built for AI agents and autonomous software. Canadian-market vehicle dimensions and weights from NHTSA vPIC's Canadian Vehicle Specifications dataset.
There is no signup and no API key. An agent (or any HTTP client) hits the endpoint, receives an x402 "402 Payment Required" challenge, signs a sub-cent USDC payment on Base or Solana, and retries — the data comes back on the paid request. That makes it a drop-in canadian specs data source for an agent tool-use loop, an MCP host, or a backend that needs vehicle data on demand without onboarding to yet another vendor portal.
