Phone Validity Check

Check phone number validity, type, and WhatsApp status using the Open Platform API.

Overview

This skill provides access to phone validity detection through a single interface:

• Phone Validity Check (phone_validity_check.py): Check phone number validity, type, and WhatsApp status

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/phone_validity_check.py. Do NOT use shell compound commands like cd scripts && python phone_validity_check.py.

Phone Validity Check (phone_validity_check.py)

Check phone number validity, type, and WhatsApp status.

Parameters: See Phone Validity API

Examples:

bash

# Check single phone number
python scripts/phone_validity_check.py --phones "[phone]"

# 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

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/validation/phone","requestId":"f47ac10b58cc4372a5670e02b2c3d479","context":"Phone validity check 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

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.

Decision Guide

User Intent	Use API
"Check if phone number is valid"	Phone Validity Check

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

• Phone Validity: Check references/phone-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
