I built a tool to fix that.</p> <p>Here's the technical approach behind LeadTrapper:</p> <h2> The Problem </h2> <p>Google Maps doesn't have a public API for bulk business data.<br> Existing tools are either too expensive ($200+/month) or too slow.</p> <h2> The Approach </h2> <ol> <li>Query the Maps search endpoint with a business category + city</li> <li>Parse the response for name, phone, address, rating, website</li> <li>Deduplicate against previously seen leads using SQLite</li> <li>Batch the results — 847+ leads returned in under 4 seconds</li> </ol> <h2> WhatsApp Delivery </h2> <p>Once you have the leads, the tool connects via WhatsApp Web <br> (no API key needed) and sends personalized messages to each contact.</p> <p>The dedup layer uses a hash of the phone number so you never <br> message the same business twice.</p> <h2> Current Status </h2> <p>Still finalizing the product. Landing page is live at <br> <a href="https://useleadtrapper.com" rel="noopener noreferrer">LeadTrapper</a> — launching soon.</p> <p>Curious if anyone here has built similar scraping pipelines and <br> how you handled rate limiting at scale.</p> webdev python discuss showdev
