Taxas de diária federal CONUS por cidade, condado ou CEP, além dos totais da viagem com a regra de 75%
Cada ponto de extremidade retorna dados específicos relacionados às taxas federais de diárias, incluindo taxas de hospedagem, detalhamentos de M&IE, totais de viagem e informações de áreas não padrão. Por exemplo, o ponto de extremidade de totais de viagem fornece custos de hospedagem para cada noite e cálculos de M&IE com base nas datas de viagem
Os campos principais incluem "localização" (nome e estado), "acomodação" (tarifa), "mie" (Despesas de Refeições e Incidentes), "anoFiscal" e "meses" (para tarifas de acomodação). Cada ponto final possui campos exclusivos relevantes para seus dados específicos, como "pernas" nos totais de viagem
Os parâmetros variam de acordo com o ponto de extremidade. Para o ponto de extremidade das taxas diárias, você pode especificar "cidade", "estado", "condado", "CEP" e "data". O ponto de extremidade dos totais da viagem requer datas de "início" e "fim", enquanto o ponto de extremidade da quebra de M&IE foca em anos fiscais
Os dados da resposta estão estruturados no formato JSON, organizados em objetos aninhados. Por exemplo, a resposta dos totais da viagem inclui matrizes para "pernas" e "linhas", detalhando cada parte da viagem e os custos associados, facilitando a análise e utilização
Os dados são extraídos da Administração de Serviços Gerais (GSA) e dos arquivos do Escritório do Censo. A API inclui hashes SHA-256 para integridade dos dados, garantindo que os usuários possam verificar a autenticidade dos dados fornecidos
Casos de uso típicos incluem calcular despesas de viagem para funcionários federais orçamentar viagens e analisar taxas diárias em diferentes locais Os usuários também podem comparar tarifas de hospedagem e M&IE em vários anos fiscais
Os usuários podem utilizar os dados retornados extraindo campos-chave para relatórios ou análises Por exemplo eles podem calcular o custo total de viagem somando os valores de hospedagem e M&IE do endpoint de totais de viagem ou avaliar as variações nas tarifas por mês
Se a API retornar resultados parciais ou vazios os usuários devem verificar os parâmetros quanto à precisão Para locais ambíguos a resposta indicará "alternativas" para ajudar os usuários a refinarem suas consultas Sempre garantir que a data e o local especificados sejam válidos
