      Overview

      This API adopts a POST request method. You can submit a job to perform hash calculation and asynchronously return a calculated hash value.

      Billing Description

      Calling the API will incur hash calculation fees and COS read request fees as described in Request Fees.
      If the files are stored in COS STANDARD_IA storage class, calling the API will incur STANDARD_IA data retrieval fees as described in Data Retrieval Fees.
      Calculation is not supported for files stored in the ARCHIVE or DEEP ARCHIVE storage classes. To calculate hash values for these files, you first need to restore them as instructed in POST Object restore.

      Restrictions

      Supported file size: Calculation on files that are less than 50 GB is supported.
      Calling the API requires a signature. For more information, see Request Signature.
      This API can be used in Beijing, Shanghai, Guangzhou, Chengdu, Hong Kong (China), Singapore, and Silicon Valley regions.

      Request
