Domain validity check, verify domain availability and DNS configuration for B2B lead qualification. Helps sales teams, marketers, and researchers validate company domains, check email server configuration, and improve outreach deliverability — essential for lead verification, email marketing, and contact data enrichment.

Check domain validity, security, and sensitivity status. Returns validation status, reason, and sensitivity flag for each domain.

Domain Validity Check

Check domain validity, security, and sensitivity status using the Open Platform API.

Overview

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

• Domain Validity Check (domain_validity_check.py): Check domain validity and security

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

Domain Validity Check (domain_validity_check.py)

Check domain validity and security status.

Parameters: See Domain Validity API

Examples:

bash

# Check single domain
python scripts/domain_validity_check.py --domains "google.com"

# Check multiple domains
python scripts/domain_validity_check.py --domains "google.com fake-domain-xyz123456.com github.com"

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

Domain 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.

Workflow

Decision Guide

User Intent	Use API
"Check if domain is safe"	Domain 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

API Documentation Reference

• Domain Validity: Check references/domain-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
