Leadmagic toolkit

LeadMagic Toolkit

Overview

LeadMagic is the engine that powers email finding, verification, and enrichment for thousands of GTM teams. This skill is the master toolkit: every endpoint, every integration pattern, every workflow, and every advanced tactic. The mistake: using the API one call at a time manually. The fix: automated workflows, waterfall enrichment, MCP tool orchestration, and integration into every tool in your stack.

Authoritative Foundations

• LeadMagic API — Email finder, verifier, waterfall enrichment endpoints — Email finder, verifier, waterfall enrichment endpoints
• MCP (Model Context Protocol) — Anthropic AI tool integration — Model Context Protocol — tool servers for agent-safe CRM and enrichment access.
• Clay — Waterfall enrichment and prospecting platform — Waterfall enrichment, Claygent research, and table-based GTM automation.
• n8n — Open-source workflow automation — Workflow automation — HTTP nodes, webhooks, and GTM glue between tools.
• Pat Spielmann — Portable data layer — Portable data layer
• Pat Spielmann — Cold to Gold — Cold to Gold

Platform Capabilities

Core Endpoints

• Email Finder: Find email from name + company or name + domain
• Email Verifier: Verify deliverability with confidence scoring
• Waterfall Enrichment: Multi-source enrichment with provider chaining
• Bulk Processing: CSV upload, async batch processing, webhook callbacks
• Job Change Detection: Monitor contacts for job changes

Integration Methods

• REST API: Direct HTTP calls with API key authentication
• CLI: Command-line tool for scripting and automation
• MCP Server: 16 tools exposed as MCP tools for AI agents
• Clay Integration: Native Clay enrichment provider
• n8n Integration: HTTP Request nodes for workflow automation
• CRM Integration: HubSpot, Salesforce, Attio via API/webhook

Workflow Patterns

Pattern 1: Single Email Find + Verify

Input: name + company → API: Email Finder → Email → API: Email Verifier → Confidence score
CLI: lm find "Jane Smith" "Acme Corp" | lm verify

Pattern 2: Bulk CSV Enrichment

Upload CSV → API: Bulk Enrich → Poll status → Download results → CRM import
CLI: lm bulk-enrich contacts.csv --output enriched.csv --webhook https://...

Pattern 3: Waterfall Enrichment (Clay)

Input → LeadMagic → if not found → Apollo → if not found → ProspectingTool → Output

Pattern 4: MCP Orchestration

AI Agent → MCP Tool: find_email → MCP Tool: verify_email → MCP Tool: enrich_person

Clay Integration Pattern

1. Add LeadMagic enrichment to Clay table
2. Map: Name column → LeadMagic Name, Company column → LeadMagic Company
3. Configure: waterfall order (LeadMagic first, then fallbacks)
4. Run: 1 credit per email found + verified

Implementation Checklist

• API key configured and tested
• CLI installed and configured
• MCP server running (if using AI agents)
• Webhook endpoints configured for bulk callbacks
• Rate limits understood and handled (exponential backoff)
• Clay integration with waterfall fallback configured
• n8n workflow templates ready for common patterns

Common Pitfalls

1. No waterfall fallback. LeadMagic → nothing. Apollo would have found it. Fix: Always chain providers. LeadMagic first. Apollo/Clearbit second.
2. No webhook for bulk. Poll status in a loop. Timeout. Job lost. Fix: Webhook callbacks. Job ID → webhook notifies on completion.
3. Hard-coding API keys in n8n. Committed to repo. Leaked. Fix: n8n credentials store. Environment variables. Never hard-code.

Output Format

The agent delivers a LeadMagic integration blueprint matched to the user's stack and use case:

• Integration Method Selection: recommended access pattern (REST API direct, CLI script, MCP server for AI agents, Clay enrichment column, or n8n HTTP Request node) with rationale for the user's workflow type
• Workflow Design: end-to-end data flow diagram — input source → find endpoint → verify endpoint → enrichment endpoint → destination system (CRM, sequencer, or data store)
• Code/Config Artifact: ready-to-use CLI commands, n8n workflow JSON snippet, or Clay column configuration for the chosen pattern — including auth header format and field mappings
• Credential & Rate-Limit Setup: API key configuration steps, rate-limit thresholds (requests per minute), exponential backoff pattern for 429 responses, and bulk webhook callback URL setup
• Fallback Chain: waterfall provider order (LeadMagic first → secondary provider on miss) with per-miss handling logic and confidence-score threshold for accepting results
• QA Checklist: 7-point validation covering API connectivity test, waterfall coverage rate on a sample, webhook delivery confirmation, credential security review, enrichment accuracy spot-check (10 known contacts), bulk job completion handling, and CRM field mapping verification

Quality Check

Before delivering, verify:

• All required sections complete
• Output matches the user's stated need
• No vague or unsupported claims
• Frameworks cited where applicable

Execution Artifacts

• references/framework-notes.md — named frameworks, citation anchors, and operating assumptions
• templates/output-template.md — copy-paste deliverable structure for the user
• scripts/check-output.py — local checklist validator for required sections This skill includes lightweight artifacts the agent can load on demand:
• ../../outbound/cold-email-copywriting/references/pat-spielmann-outbound-copy.md — GTM stack + outbound copy integration patterns (Pat Spielmann) Use the artifacts when the user asks for an implementation-ready deliverable, a repeatable workflow, or a quality check rather than generic advice.
