Las tarifas por día de la federal CONUS por ciudad, condado o código postal, más los totales del viaje con la regla del 75%
Cada punto final devuelve datos específicos relacionados con las tarifas federales de viáticos, incluidos los costos de alojamiento, desglose de M&IE, totales de viajes e información sobre áreas no estándar. Por ejemplo, el punto final de totales de viaje proporciona los costos de alojamiento por cada noche y los cálculos de M&IE basados en las fechas de viaje
Los campos clave incluyen "ubicación" (nombre y estado) "alojamiento" (tarifa) "mie" (Gastos de Comidas y Otros Gastos) "añoFiscal" y "meses" (para tarifas de alojamiento) Cada punto final tiene campos únicos relevantes para sus datos específicos como "tramos" en los totales del viaje
Los parámetros varían según el punto final. Para el punto final de tarifas diarias, puede especificar "ciudad", "estado", "condado", "código postal" y "fecha". El punto final de totales del viaje requiere fechas de "inicio" y "fin", mientras que el punto final de desglose de M&IE se centra en los años fiscales
Los datos de respuesta están estructurados en formato JSON organizados en objetos anidados Por ejemplo la respuesta de totales del viaje incluye arreglos para "piernas" y "líneas" detallando cada tramo de viaje y los costos asociados facilitando su análisis y utilización
Los datos se obtienen de la Administración de Servicios Generales (GSA) y de los archivos de la Oficina del Censo La API incluye hashes SHA-256 para la integridad de los datos asegurando que los usuarios puedan verificar la autenticidad de los datos proporcionados
Los casos de uso típicos incluyen calcular gastos de viaje para empleados federales, presupuestar viajes y analizar tarifas por día en diferentes ubicaciones Los usuarios también pueden comparar tarifas de alojamiento y M&IE a través de varios años fiscales
Los usuarios pueden utilizar los datos devueltos extrayendo campos clave para informes o análisis Por ejemplo pueden calcular los costos totales de viaje sumando los valores de alojamiento y M&IE de la endpoint de totales del viaje o evaluar las variaciones en las tarifas por mes
Si la API devuelve resultados parciales o vacíos, los usuarios deben verificar la precisión de los parámetros. Para ubicaciones ambiguas, la respuesta indicará "alternativas" para ayudar a los usuarios a refinar sus consultas. Siempre asegúrese de que la fecha y la ubicación especificadas sean válidas
