Self-Hosted Clearbit and Clay Alternative: Enrich Inbound Webhooks for 0.0005 USD per Lead

Description and use

A self‑hosted pipeline replaces paid Clearbit/Clay services, enriching 1,000 inbound leads for under 0.50 USD using n8n, a FastAPI scraper, and GPT‑4o‑mini.

Problem

Paying 300+ USD/month for Clay or Clearbit to enrich basic inbound form webhooks destroys margins for B2B SaaS or automation agencies.

Outcome

The pipeline replaces paid enrichment services, reducing cost to 0.50 USD for 1,000 leads while delivering real‑time data and automated scoring.

Workflow

• Receive inbound webhook in n8n
• Trigger FastAPI scraper to fetch company homepage
• Send scraped data to GPT‑4o‑mini for enrichment
• Return JSON with icp_score and priority
• Route high‑priority leads to #sales‑alerts in Slack with draft reply

Evidence

By pairing a self-hosted n8n workflow with a lightweight Python FastAPI scraper and OpenAI GPT-4o-mini, you can qualify and enrich 1,000 inbound leads for less than 0.50 USD total.
