UpKuaJing Email Tool

Send emails and track email task status using the UpKuaJing Open Platform API.

Overview

This skill provides access to UpKuaJing's email service through:

• Email Send (mail_send.py): Send emails to recipients
• Email Task List (mail_task_list.py): View email task list with time range filter
• Email Task Record List (mail_task_record_list.py): View detailed records for a specific task

Running Scripts

Environment Setup

1. Check Python: python --version
2. Install dependencies: pip install -r requirements.txt

Script directory: scripts/*.py Run example: python scripts/*.py

Important: Always use direct script invocation like python scripts/mail_task_list.py. Do NOT use shell compound commands like cd scripts && python mail_task_list.py.

Three Main APIs

Email Send (mail_send.py)

Send emails to recipients.

Parameters: See Email Send API

Examples:

bash

# Send a simple email
python scripts/mail_send.py \
  --subject "Test Email" \
  --content "This is the email content" \
  --emails '["[e-mail]"]'

# Send email with reply address
python scripts/mail_send.py \
  --subject "Test Email" \
  --content "This is the email content" \
  --reply_email "[e-mail]" \
  --emails '["[e-mail]"]'

# Send to multiple recipients
python scripts/mail_send.py \
  --subject "Test Email" \
  --content "This is the email content" \
  --emails '["[e-mail]","[e-mail]"]'

Email Task List (mail_task_list.py)

View email task list with optional time range filter.

Parameters: See Email Task List API

Examples:

bash

# Get task list (first page, 10 items)
python scripts/mail_task_list.py --page_no 1 --page_size 10

# Filter by time range
python scripts/mail_task_list.py \
  --start_time 1775812273 \
  --end_time 1775900000 \
  --page_no 1 \
  --page_size 10

# Filter by status (0-待发送 1-发送中 2-发送完成)
python scripts/mail_task_list.py --status 2 --page_no 1 --page_size 10

Email Task Record List (mail_task_record_list.py)

View detailed records for a specific email task.

Parameters: See Email Task Record List API

Examples:

bash

# Get records for task ID 1496
python scripts/mail_task_record_list.py --task_id 1496 --page_no 1 --page_size 10

# Filter by time range and status
python scripts/mail_task_record_list.py \
  --task_id 1496 \
  --start_time 1775812273 \
  --end_time 1775900000 \
  --status 2 \
  --page_no 1 \
  --page_size 10

API Key and UpKuaJing Account

• API Key: Stored in ~/.upkuajing/.env file as UPKUAJING_API_KEY
• First check: If not set, prompt user to provide or apply at UpKuaJing Open Platform

API Key Not Set

First check if the ~/.upkuajing/.env file has UPKUAJING_API_KEY; If UPKUAJING_API_KEY is not set, prompt the user to choose:

1. User has one: User provides it (manually add to ~/.upkuajing/.env file)
2. User doesn't have one: Guide user to apply at UpKuaJing Open Platform Wait for user selection;

Account Top-up

When API response indicates insufficient balance, explain and guide user to top up:

1. Create top-up order (auth.py --new_rec_order)
2. Based on order response, send payment page URL to user, guide user to open URL and pay, user confirms after successful payment;

Get Account Information

Use this script to get account information for UPKUAJING_API_KEY: auth.py --account_info

Report Skill Call Errors

When an API call fails or returns abnormal data (server error, timeout, malformed response, etc.), explain the anomaly to the user in natural language and ask whether to report it to the platform for troubleshooting. Only run the report after user confirmation:

bash

python scripts/error_report.py --params '{"requestPath":"/agent/mail/send","requestId":"f47ac10b58cc4372a5670e02b2c3d479","context":"Email send failed with a server error"}'

• Do not report normal business conditions (insufficient balance, invalid API key, parameter errors) — handle them via their own flows
• Error reporting does not incur query fees
• Parameters: See Error Report API

Fees

Email sending API calls incur fees, different interfaces have different billing methods. Latest pricing: Users can visit Detailed Price Description Or use: python scripts/auth.py --price_info (returns complete pricing for all interfaces)

Email Send Billing Rules

Email sending is charged — each send request incurs a fee based on the number of recipients.

Task List & Record List Billing Rules

Free of charge — No fees for task list and task record list queries.

Fee Confirmation Principle

Any operation that incurs fees must first inform and wait for explicit user confirmation. Do not execute in the same message as the notification.

Workflow

Decision Guide

User Intent	Use API
"Send an email"	Email Send
"View my email tasks"	Email Task List
"Check email delivery status"	Email Task Record List
"Find tasks in a time range"	Email Task List (with start_time/end_time)

Email Send Flow

1. Prepare email content: Subject, content, recipients
2. Execute send: Use mail_send.py with appropriate parameters
3. Get response: API returns task result synchronously

Task Check Flow

1. View task list: Use mail_task_list.py with optional time filter
2. Get task ID: From the task list response
3. View task records: Use mail_task_record_list.py with task_id

Error Handling

• API key invalid/non-existent: Check UPKUAJING_API_KEY in ~/.upkuajing/.env file
• Insufficient balance: Guide user to top up
• Invalid parameters: Must first check the corresponding API documentation in references/ directory, get correct parameter names and formats from documentation, do not guess
• Skill call errors / abnormal responses: Explain to the user and, with user confirmation, report to the platform via python scripts/error_report.py (see Report Skill Call Errors)

API Documentation Reference

• Email Send: Check references/email-send-api.md
• Email Task List: Check references/email-task-list-api.md
• Email Task Record List: Check references/email-task-record-list-api.md
• Error Report: Check references/skill-error-report-api.md

Notes

• File paths use forward slashes on all platforms
• Do not guess parameter names, get accurate parameter names and formats from documentation
• Prohibit outputting technical parameter format: Do not display code-style parameters in responses, convert to natural language
• Do not estimate or guess fees — use python scripts/auth.py --price_info to get accurate pricing information
• Email sending is synchronous submission: The API returns response immediately after submission, but the email server processes asynchronously; the status field in response indicates sending status (0-pending 1-sending 2-completed)
