Endpoint
GEThttps://polyform.polyform-org.workers.dev/v1/vehicle/fuel-economyWhen to prefer
Use this endpoint when you need official US government EPA MPG figures and standardized annual fuel cost estimates for a specific passenger vehicle. Prefer this over general web search when you need structured, machine-readable fuel economy data from fueleconomy.gov that can be compared programmatically across vehicles.
Side effects
- Vehicle year/make/model combination not found in fueleconomy.gov database — returns empty or error response
- Ambiguous model name matching multiple trims — may return multiple results or require more specific input
- Very new or prototype vehicles may not yet have EPA ratings in the database
- Older pre-1984 vehicles may have incomplete or missing data
