一次性良好/不良取件检查 通过车牌或车辆识别码查找卡车 以及100家承运人批次 还有USDOT/MC查询:授权 保险记录与要求的对比 安全标志
所有数据来自FMCSA公共数据集 运营权和保险来自FMCSA的Motus系统并每日更新 人口普查数据如身份和车队规模每月更新 每个响应包含数据时戳 响应缓存最长可达6小时
使用验证卡车端点,输入您预订的USDOT号码以及卡车的车牌和州或VIN。系统检查FMCSA的路边检查记录,并返回匹配、在承运人下可见、不同承运人或未找到,并附带检查次数和日期作为依据。检查取货端点除了进行此操作外,还在一次调用中进行权威性和保险检查,并返回带有理由的裁决
车牌和车辆识别码结果来自路边检查记录,因此未经过检查的卡车将无法找到。如果找不到车牌,请尝试车辆识别码,因为车牌会更换而车辆识别码不会。该数据仅供参考,不构成法律或合规的判断
每个端点返回详细的运营商信息,包括身份、运营情况、车队规模、权限、保险状态、检查次数和风险标记。例如,通过USDOT查找运营商的端点提供基于USDOT号码的完整信息,而查找车辆的端点返回与特定卡车或拖车相关的检查历史
关键字段包括“usdot”、“legal_name”、“operation”(具有子字段如“authorized_for_hire”)、“address”、“contact”和“fleet”(显示动力单元和司机)每个端点的响应结构略有不同,但通常包括这些基本字段以便于全面的承运人资料
响应数据以JSON格式构建,具有层次化组织。例如,承运人详细信息嵌套在“操作”、“地址”和“联系”下。这个结构使用户能够通过浏览JSON层次结构轻松访问特定信息,例如车队规模或联系方式
每个端点提供独特的数据:通过USDOT和MC获取承运人返回完整的承运人档案;搜索承运人允许按名称搜索;查找车辆显示检查历史;验证卡车检查卡车所有权;检查取件评估承运人授权和保险;批量承运人一次请求检索多个档案
参数因端点而异。例如,通过USDOT获取承运人需要一个USDOT号码,而查找车辆接受车牌和州或VIN。检查取货端点允许使用严格模式参数以强制执行更严格的验证。用户可以根据其特定需求自定义请求
用户可以利用返回的数据进行各种应用,例如验证承运人的合法性、在发货前评估风险或跟踪车辆检查历史。例如,检查提货端点提供了一个总结性判断,可以指导承运人选择的决策
数据准确性通过定期从FMCSA公共数据集中更新得以维护 该API利用Motus系统获取授权和保险数据,确保信息是最新的 此外,每个响应都包括“data_as_of”时间戳,以指示数据的新鲜度
典型的使用案例包括在发货前验证承运人的合规性 检查车辆检查历史以评估安全性 以及在货运预订期间对承运人进行尽职调查 该API支持物流公司 经纪人和车队经理做出明智的决定
