按城市、县或邮政编码计算的CONUS联邦每日津贴标准,加上符合75%规则的旅行总费用
每个端点返回与联邦每日津贴金额相关的具体数据,包括住宿费 M&IE 细分 旅行总计和非标准区域信息 例如 旅行总计端点提供每晚的住宿费用和基于旅行日期的M&IE计算
关键字段包括“地点”(名称和州) “住宿”(费用) “mie”(餐饮和杂项费用) “财务年度”和“月份”(用于住宿费) 每个端点都有与其特定数据相关的唯一字段,例如“行程总计”中的“腿”
参数因端点而异。对于每日津贴费率端点,您可以指定“城市”、“州”、“县”、“邮政编码”和“日期”。行程总计端点需要“开始”和“结束”日期,而M&IE细分端点则专注于财政年度
响应数据以JSON格式结构化,组织成嵌套对象。例如,行程总计响应包括“腿”和“线路”的数组,详细列出每个旅行腿和相关费用,使解析和利用变得容易
数据来源于总务管理局(GSA)和人口普查局文件 该API包括SHA-256哈希以确保数据完整性 确保用户可以验证提供的数据的真实性
典型的用例包括为联邦员工计算差旅费用、预算旅行开支以及分析不同地点的每日津贴率 用户还可以比较不同财政年度的住宿费用和餐饮津贴
用户可以通过提取关键字段来利用返回的数据进行报告或分析。例如,他们可以通过将旅费总终端中的住宿和餐饮费用值相加来计算总旅行成本,或按月份评估费率的变化
如果API返回部分或空的结果,用户应该检查参数的准确性。对于模糊的位置,响应将指示“备选项”以帮助用户精炼他们的查询。始终确保指定的日期和地点是有效的
