GSA Fleet leases vehicles to federal agencies on a full-service basis: each vehicle type — identified by its Standard Item Number (SIN) — has a monthly lease rate plus a rate per mile, with maintenance and fuel expenses included in that pricing. GSA publishes these rates once per fiscal year as Excel rate bulletins, in separate US and Europe schedules, with a 10% surcharge on standard rates for vehicles domiciled OCONUS outside Europe. Allowances API turns those spreadsheets into a simple JSON endpoint, so your application can look up the leasing rates for any vehicle type and fiscal year.
Sedans, SUVs, vans, trucks, buses, ambulances, EVs and more — every SIN priced in the GSA Fleet rate bulletins.
Both components of the full-service lease, as clean JSON numbers instead of spreadsheet cells.

"Set per vehicle" means GSA Fleet prices the monthly rate individually for that
vehicle type (the API returns a
monthly_rate_type field explaining each case).
Optional equipment is charged separately by GSA and is not part of these rates.

GSA publishes its Fleet leasing rates as downloadable Excel bulletins — one per fiscal year and schedule, each with hundreds of vehicle types. Budgeting and fleet-management systems that copy figures out of those spreadsheets go stale every October when the new bulletin lands. Allowances API monitors the official publication, keeps every bulletin since fiscal year 2022, and answers the question your code actually asks: what are the monthly and per-mile rates for this vehicle type in this fiscal year?

GSA publishes its Fleet vehicle leasing rates as fiscal-year rate bulletins in Excel format, not as an API. Allowances API republishes those bulletins as a normalized JSON API, queryable by Standard Item Number (SIN), fiscal year, and rate schedule.
GSA Fleet leases are full-service: each vehicle type has a monthly lease rate and a rate per mile, and that pricing includes maintenance and fuel expenses. Optional equipment is charged separately by GSA, per its official vehicle rates page.
A Standard Item Number is GSA's identifier for a leased vehicle type — for
example 10B is a midsize sedan and 99 is a 4x4 sport
utility vehicle. The API takes the SIN as a case-insensitive path parameter
and returns the vehicle description alongside the rates.
Yes. The API covers every GSA Fleet rate bulletin from fiscal year
2022 onward. Pass
year and the API returns the monthly and mileage rates that
applied in that fiscal year — useful for reconciling past bills and validating
historical cost models.
The API serves both GSA Fleet schedules: standard for vehicles
leased in the United States and europe for vehicles leased in
Europe. Per GSA, vehicles domiciled OCONUS outside Europe are charged the
standard rates plus a 10% surcharge.
No. Allowances API is not affiliated with GSA or any U.S. Government agency. Data is sourced from the official GSA Fleet vehicle rates publication, and every response can include a verification link back to that source.
