What Web Yu-pri CLI does

The Web Yu-pri CLI skill enables users to interact with Japan Post's Web Yu-pri service directly from the command line, facilitating the entry of shipping label data in a streamlined manner. This tool is particularly useful for those who frequently need to fill out repetitive contents for shipping labels, allowing for automation of the process while maintaining control over the final entries. By leveraging a real browser UI, it ensures that users can log in securely and manage their shipping tasks efficiently.

To get started, users can install the skill via pip, and if no browser is found, they can install Chromium using Playwright. The skill provides a range of commands to open the login interface, check status, plan item entries, and perform dry runs before actual submissions. This ensures that users can verify their entries without the risk of making mistakes during the live process, as it does not automate final confirmation clicks.

The skill requires users to prepare their item data in JSON format, allowing for flexibility in how they structure their entries. It also supports CSV headers with various aliases, making it easier to integrate with existing workflows. Users are advised to follow safety rules regarding credential management and to keep item lines distinct to ensure accurate total values are reported. Overall, this CLI tool is designed for developers and logistics professionals who need to streamline their shipping label processes while maintaining accuracy and security.

Safety Rules

  • Do not put Japan Post credentials in commands, files, logs, or prompts.
  • Use open-login so the user can log in manually in the persistent profile.
  • Run contents fill ... --dry-run --json before live form filling.
  • This CLI does not click final shipment confirmation or purchase buttons.
  • Keep item lines separate when the source data has separate award/category lines, while preserving the requested declared total.

Common Commands

cli-anything-web-yu-pri --json doctor
cli-anything-web-yu-pri open-login
cli-anything-web-yu-pri --json status --url https://mgr.post.japanpost.jp/M060800.do

Items File

JSON:

{
  "items": [
    {"description": "Award plaque", "value": 8000, "quantity": 1, "country": "KR"},
    {"description": "Certificate", "value": 9000, "quantity": 1, "country": "KR"}
  ]
}

CSV headers can use these aliases:

  • description: description, desc, content, contents, item, name, pkg
  • value: value, declared_value, cost, price, amount, yen, jpy

  • country: country, country_code, country_of_origin, origin, couCd, cou_cd

By default, value is treated as the line declared value. Use --value-mode unit when value should be multiplied by quantity.
