LeadMagic

What it is, in plain English

LeadMagic positions itself as a B2B data API for GTM engineers and AI agents, with access through REST, CLI, and MCP alongside integrations into tools like Clay and common sequencers.

The product surface includes email finder and validation, mobile finder, company enrichment, profile URL enrichment, personal email discovery, catch-all validation helpers, hiring and intent-style signals, plus bulk and automation-oriented workflows.

How we use it on real work

We use LeadMagic as programmable enrichment behind tables, agents, and custom internal tools, not as the place reps click all day.

• Separate dev and production keys and rotate on any leak.
• Cap credits per client or campaign so agents do not run wild.
• Standardize which endpoints are allowed for outreach-eligible records.
• Measure downstream bounce and reply rates, not just API success codes.

How we teach it in the community

Beginners call one endpoint from a script or sheet. Advanced students design multi-step enrichment with guardrails.

• Exercise: email finder plus validation on 50 rows with documented failure handling.
• Compare MCP usage versus direct API for your stack.
• Security talk: data retention and acceptable use for client contracts.

Good fit, and when we’d pick something else

LeadMagic fits teams with engineering or ops capacity who want flexible B2B data access across workflows.

• Good when: you build in Clay, agents, or custom automation.
• Good when: you need many endpoint types behind one key.
• Skip when: nobody can maintain API integration quality.
• Skip when: reps only need a simple Chrome extension workflow.
