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

# Check multiple phone numbers
python scripts/phone_validity_check.py --phones "[phone] [phone] [phone]"

API Key and Account

• API Key: Stored in ~/.upkuajing/.env file as UPKUAJING_API_KEY
• First check: If not set, prompt user to provide or apply at 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 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: auth.py --account_info

Fees

Phone validity check API calls incur fees. Latest pricing: Users can visit Detailed Price Description Or use: python scripts/auth.py --price_info (returns complete pricing for all interfaces)

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.

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

API Documentation Reference

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
