Could you build this?
Partial Bulk checking WhatsApp presence requires interacting with WhatsApp's private protocol or unofficial multi-device APIs, which are aggressively rate-limited and blocked by Meta without careful anti-detection infrastructure.
What it would actually take: To build a reliable bulk checker, one needs a cluster of headless browsers or emulated WhatsApp Web client sessions (e.g., via Baileys or Puppeteer) behind a rotating residential proxy pool. The hard part is evading WhatsApp's automated anti-abuse detection, ban waves, and rate limits when querying thousands of phone numbers, which requires ongoing reverse engineering of WhatsApp's network protocol.
