Cars / VIN API
Decode any Vehicle Identification Number (VIN) into make, model, year, body class, engine, fuel type, drivetrain and plant — and browse vehicle makes and models by type and year. Powered by the official NHTSA vPIC database.

NHTSA Vehicle API
US vehicle data as an API, built on the official NHTSA datasets. Decode any VIN into make, model, year, trim, body class, engine, drivetrain, fuel type and assembly plant. Browse the full catalogue of vehicle makes and the models offered for any make and year. Then pull the safety record for a vehicle: open recalls with the affected component, the manufacturer summary, consequence and remedy; owner complaints flagging crashes, fires, injuries and deaths; and the official NCAP crash-test star ratings (overall, frontal, side and rollover). Real government data, no key needed upstream. Ideal for car marketplaces, dealer tools, VIN-lookup widgets, insurance and recall-check apps.

Vehicle Database API
Decode any Vehicle Identification Number (VIN) into a full, structured vehicle specification — make, manufacturer, model, year, trim, series, body class, vehicle type, drive type, doors, engine (cylinders, displacement, horsepower, configuration and primary/secondary fuel), transmission style, gross vehicle weight rating and the manufacturing plant (country, city, state, company). Partial VINs with wildcards are supported and an optional model year improves accuracy. The API also lists every vehicle make (optionally for a vehicle type such as car, truck or motorcycle) and all models for a given make and year. Backed by the official NHTSA vPIC database, with clean, predictable JSON and no raw-data wrangling. Every endpoint accepts input via the query string or the request body. Ideal for automotive marketplaces, insurance and fleet tools, dealer and parts catalogues, and vehicle-registration flows.

FuelEconomy.gov API
Official US vehicle fuel-economy data as an API, powered by FuelEconomy.gov — the joint US EPA and Department of Energy resource behind the fuel-economy window sticker on every car, SUV and truck sold in the United States since 1984. Browse the catalogue step by step — model years, then makes, then models, then the engine/transmission trims (each carrying the vehicle id you need for the detail call) — and pull a vehicle's complete fuel-economy record: city, highway and combined MPG, fuel type, engine (number of cylinders and displacement), transmission, EPA vehicle class and drivetrain, the estimated annual fuel cost, tailpipe CO2 emissions in grams per mile, the barrels of petroleum consumed per year and the estimated five-year fuel-cost saving (or extra spend) versus an average new vehicle. Ideal for car-shopping and comparison tools, total-cost-of-ownership and emissions calculators, fleet management and sustainability reporting. The data is authoritative, official EPA/DOE test data and is public domain; it covers US-market light-duty vehicles. Vehicle ids come from the trims endpoint, reached via the year -> make -> model -> trim chain.

Turbocharger Boost API
Turbocharger and boost engineering maths as an API, computed locally and deterministically — the pressure-ratio, charge-air and airflow numbers a tuner, engine builder or motorsport engineer sizes forced induction with. The pressure-ratio endpoint gives the compressor pressure ratio = absolute manifold pressure ÷ ambient = (atmospheric + boost) ÷ atmospheric, so 10 psi at sea level is a 1.68 ratio — the x-axis of every compressor map, which climbs at altitude where ambient pressure is lower. The charge-air endpoint shows why an intercooler matters: compressing air heats it (T₂ = T₁ × (1 + (PR^0.2857 − 1)/efficiency)), and hot air is less dense, so the real gain is the charge density ratio = pressure ratio × (T₁/T_charge), not the pressure ratio alone — 10 psi at 70 % compressor efficiency makes ~93 °C and a 1.37 density ratio with no intercooler, rising toward 1.6 once an intercooler claws back the heat, and the estimated power gain tracks the density. The airflow endpoint gives the engine mass airflow ≈ displacement × (rpm/2) × volumetric efficiency × charge density, in lb/min — the y-axis of the compressor map you plot against the pressure ratio to land in the efficient island and avoid surge or choke. Everything is computed locally and deterministically, so it is instant and private. Ideal for engine-tuning and turbo-sizing tools, dyno and data-logging apps, and motorsport calculators. Pure local computation — no key, no third-party service, instant. Sizing estimates — verify on a dyno. 3 compute endpoints. For engine displacement and compression use an engine API; for shop compressed air a compressor API.
