Evaluation criteria
Bulk support, pricing clarity, WhatsApp focus, and AI-agent integration.
Where Proweblook falls short
No MCP server or Chrome extension
It's an API and web checker only, so there's no AI-agent integration and no in-browser bulk checking without writing code.
Part of a wider multi-purpose API toolkit
WhatsApp checking sits alongside phone validation, caller ID, and GeoIP lookups, so it's positioned as a generalist verification API rather than a WhatsApp specialist.
Bulk CSV upload not advertised
The public site highlights a single-number online checker and an API; a self-serve CSV upload flow for bulk lists isn't documented.
