⚙️ How It Works

The WhatsApp Number Lookup — Profile, Telegram, Bulk actor accepts one or more US phone numbers, sanitizes and validates each into an 11-digit format, then fetches WhatsApp's public wa.me page for that number. Response text is scanned for known "not registered" phrases, business-account indicators, and OpenGraph meta tags containing profile picture and about text. If Telegram cross-checking is enabled, the same number is also checked against Telegram's public t.me profile page for a name and avatar. All numbers are processed concurrently up to a configurable limit, and every result is pushed to the Apify Dataset together as one batch at the end of the run.

Key Processing Steps:

1. Input Parsing – Accept a single phone number or a list of US phone numbers
2. Proxy Setup – Configure Apify residential proxy if enabled, with automatic no-proxy fallback
3. Phone Sanitization – Strip non-digit characters and normalize to 11-digit US format
4. Format Validation – Reject numbers that don't match the expected 10/11-digit US pattern
5. Concurrent Dispatch – Queue all numbers for processing under a semaphore-limited concurrency pool
6. WhatsApp Check – Fetch the wa.me page and parse registration, account type, picture, and about text
7. Telegram Check – Optionally fetch the t.me page and parse name/avatar, if enabled
8. Result Assembly – Combine WhatsApp and Telegram data into one record per phone number
9. Batch Gathering – Wait for all concurrent lookups to complete via asyncio.gather
10. Dataset Push – Push the full batch of WhatsApp Number Lookup — Profile, Telegram, Bulk records at once
11. Summary Logging – Report the total number of numbers successfully checked

Key Benefits:

• Pull WhatsApp registration and profile data for any US phone number without manual checks
• Optionally cross-reference the same number on Telegram in the same run
• Process large lists of numbers concurrently for fast bulk verification
• Feed lead-verification pipelines, contact-cleaning tools, or OSINT research workflows
• Automate recurring WhatsApp Number Lookup — Profile, Telegram, Bulk checks as your contact list grows
