How this service works
MPG lookup for any US-market car since 1984: official test-cycle city, highway, and combined miles per gallon plus fuel type and CO2 per mile, by year/make/model or VIN. Multiple engine/transmission variants are returned with ids so you can query the exact one. Clean structured JSON.
Output
A structured JSON response listing all engine/transmission variants for the queried vehicle, each with a unique vehicle_id and official EPA test-cycle city MPG, highway MPG, combined MPG, fuel type, and CO2 emissions per mile. Multiple variants allow precise selection of the exact configuration.
Example use cases
Pre-purchase fuel cost research
“I'm thinking about buying a used 2017 Toyota Camry — what are the official EPA city and highway MPG figures for it, and are there different engine options I should know about?”
Fleet emissions reporting
“I need the CO2 per mile and fuel type for a 2020 Ford F-150 with VIN 1FTEW1EP9LKD12345 so I can include it in our fleet emissions report.”
Car comparison for commuters
“Can you look up the combined MPG for both a 2021 Honda Civic and a 2021 Mazda3 so I can compare how fuel-efficient they are for my daily commute?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/car-mpg-lookup?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need official EPA fuel economy figures (city/highway/combined MPG), fuel type, or CO2 emissions data for any US-market vehicle from 1984 onward. It supports both VIN-based lookup (for exact vehicle identification) and year/make/model queries, and returns all engine/transmission variants with IDs for precise filtering. Prefer this over generic car data APIs when EPA test-cycle accuracy and CO2 data are required.
Side effects
- Vehicle not found for given make/model/year combination — no results returned
- Invalid or malformed VIN — decoding fails or returns error
- Model year before 1984 — outside supported range
- Ambiguous model name matching multiple makes — requires more specific input
- Invalid vehicle_id provided — returns error or empty result
