Google bigquery 是否可以使用脚本查询公共大查询数据集，而无需注册计费

是否可以查询公共大查询数据集，例如使用C/python脚本，而无需在Google大查询上注册计费。我使用了随附的C代码，但它没有给我足够的权限[403]错误

无论您做什么，您都需要启用计费，或者从已启用的项目发送凭据

所以，请快速回答您的问题：否。您需要启用计费。但这并不意味着，如果你所做的只是查询公共数据集，你就得付钱

如本页链接文档所示，每月处理的第一TB数据是免费的。

谢谢Patrice，因为我无法在未注册的情况下使用我的脚本，我现在已经在Google Big Query上手动运行了几次查询并下载了数据。
