Paginated list of every motor vehicle manufacturer NHTSA tracks via vPIC. Each record includes the canonical Mfr_ID, full legal name, common short name (e.g., "Honda"), country, and the list of vehicle types the manufacturer produces (Passenger Car, Truck, Motorcycle, Bus, MPV, etc.). Pass the optional `manufacturer` param to substring-search Mfr_Name. 100 records per page. Backed by NHTSA.gov; data is public-domain US government records.
/api/vehicle/manufacturersPAYMENT-SIGNATURE.The manufacturers API is a pay-per-call vehicle endpoint built for AI agents and autonomous software. Paginated list of every motor vehicle manufacturer NHTSA tracks via vPIC.
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 manufacturers 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.

page | integer | 1-indexed page (100 manufacturers per page). Default 1. min 1 · max 100 |
manufacturer | string | Optional substring filter on the full Mfr_Name (case-insensitive on NHTSA side). Examples: "honda", "tesla", "general motors". min 2 chars · max 80 chars |
