Speed-to-lead is the biggest multiplier in B2B sales. Waiting hours to manually check if an inbound form email is a real company kills conversion rates.
By combining n8n with a Python FastAPI microservice and gpt-4o-mini, you can filter free email providers, scrape the company website live, score ICP fit (0-100), and draft a personalized reply in under 3 seconds.
Structured JSON Output for n8n Conditional Routing
Enforcing JSON mode in FastAPI allows your downstream n8n IF node to route high-intent leads (icp_score >= 70) straight to Slack #sales-alerts.
Why Live Scraping Beats Static Databases
Fetching the live title and meta description directly from the prospect domain via httpx gives gpt-4o-mini immediate context on what the company sells today at zero API cost.
