FAQ
Questions GSA owners ask.
- 01
How can I find the per diem rates for a specific city like Los Angeles?
You can use the get_rates_by_city capability. Just provide the city name (Los Angeles), the state abbreviation (CA), and the fiscal year you are interested in.
- 02
Is it possible to get a breakdown of meal costs for the day?
Yes! Use the get_mie_breakdown capability for a specific fiscal year. It returns the breakdown for Meals and Incidental Expenses (M&IE), showing allocations for breakfast, lunch, dinner, and incidentals.
- 03
Can I look up rates using just a ZIP code?
Absolutely. The get_rates_by_zip capability allows you to input a 5-digit ZIP code and a fiscal year to retrieve the applicable per diem rates for that specific location.
