LeadMagic Platform Help

Help the user with LeadMagic platform questions — from email/mobile finding and company enrichment through ads intelligence, job tracking, API integration, and MCP server setup for AI agents.

Step 1 — Gather context

If references/learnings.md exists, read it first for accumulated knowledge.

Ask the user:

1. What area of LeadMagic do you need help with?

   • A) Email Finder — finding verified work emails from name + company
   • B) Email Validation — verifying emails, catch-all detection, deliverability scoring
   • C) Mobile Finder — finding direct dial phone numbers
   • D) Profile Search — enriching contacts from LinkedIn/B2B profile URLs
   • E) Company Intelligence — company search, funding, technographics, competitors
   • F) Employee/Role Finder — discovering employees or specific roles at companies
   • G) Job Change Detector — tracking contacts changing jobs
   • H) Ads Intelligence — Google, Meta, B2B ad research
   • I) API Integration — REST API setup, authentication, endpoints
   • J) MCP Server — setting up LeadMagic tools in Claude, Cursor, Windsurf, VS Code
   • K) CLI — command-line usage
   • L) Credits & Billing — credit costs, plan optimization
   • M) Something else — describe it

2. What's your role?

   • A) Sales rep / AE / BDR
   • B) RevOps / GTM Ops / GTM Engineer
   • C) Developer / Engineer
   • D) Marketing / Growth
   • E) Founder / solo seller
   • F) Agency
   • G) Other

3. What are you trying to accomplish? (describe your specific goal or question)

If the user's request already provides most of this context, skip directly to the relevant step. Lead with your best-effort answer using reasonable assumptions (stated explicitly), then ask only the most critical 1-2 clarifying questions at the end — don't gate your response behind gathering complete context.

Step 2 — Route or answer directly

If the request maps to a specialized skill, route:

• Enrichment strategy / provider comparison → /sales-enrich
• Prospect list building strategy → /sales-prospect-list
• Intent signal strategy / prioritization → /sales-intent
• Competitive intelligence strategy → /sales-compete
• Email deliverability strategy → /sales-deliverability
• Tool integration architecture → /sales-integration

Otherwise, answer directly using the platform reference below.

Step 4 — Actionable guidance

When answering, always:

1. Include credit costs — every endpoint has different credit costs. Help users budget (e.g., "Finding emails for 1,000 leads = ~1,000 credits via Email Finder").
2. Emphasize free failed lookups — users only pay when data is found. This changes the ROI calculation vs flat-rate providers.
3. Recommend the right endpoint — Email Finder vs Profile to Email vs Personal Email Finder serve different use cases. Guide users to the cheapest path.
4. Consider MCP for AI workflows — if the user works in Claude, Cursor, or Windsurf, the MCP server gives them all 19 tools without writing code.
5. Suggest Clay integration — for waterfall enrichment, LeadMagic is one of Clay's 150+ providers. Users can combine LeadMagic with other providers for max coverage.

Gotchas

Best-effort from research — review these, especially items about plan-gated features and integration gotchas that may be outdated.

1. Mobile Finder costs 5x more than Email Finder. At 5 credits per valid mobile number, mobile enrichment burns credits fast. Budget separately — 1,000 mobile lookups = 5,000 credits (assuming 100% hit rate; less in practice since failed lookups are free).

2. Email to Profile is the most expensive endpoint at 10 credits. Reverse lookups (email → B2B profile) are costly. If you already have LinkedIn URLs, use Profile Search (1 credit) instead.

3. Basic plan credits don't roll over. Only Essential ($99.99/mo) and above get rollover. If you're on Basic and don't use all 2,500 credits, they expire at month end.

4. Field naming is inconsistent — mix of snake_case and camelCase. Different endpoints return fields in different conventions. When parsing responses programmatically, don't assume consistent naming. Check the OpenAPI spec or test each endpoint.

5. Rate limit on Profile Search is 300 req/min. Most endpoints don't document rate limits publicly, but Profile Search is capped at 300 requests per minute. For bulk enrichment, throttle accordingly or use the Employee Finder endpoint for discovery.

Examples

Example 1: Finding work emails for a prospect list

User says: "I have 2,000 leads with names and company domains. How do I find their work emails with LeadMagic?" Skill does: Recommends Email Finder endpoint (POST /v1/people/email-finder), shows curl example with first_name + last_name + company_name, calculates credit budget (~2,000 credits max, likely less since failed lookups are free), and suggests Essential plan ($99.99/mo, 10,000 credits) for headroom. Result: API integration guide with credit budget and plan recommendation.

Example 2: Setting up MCP server for Claude Code

User says: "I want to use LeadMagic tools directly in Claude Code for prospect research." Skill does: Walks through MCP server setup — install via npx leadmagic-mcp, configure API key, shows example usage of find_email and search_company tools within Claude. Notes all 19 tools available. Result: Working MCP setup with usage examples.

Example 3: LeadMagic vs Apollo for enrichment

User says: "Should I use LeadMagic or Apollo for email finding? We do about 5,000 lookups a month." Skill does: Compares LeadMagic's pay-per-result model (5,000 lookups @ ~$0.01 = ~$50-100/mo on Essential) vs Apollo's subscription model ($49/user/mo with credit limits). Notes LeadMagic's advantage in pay-only-for-found and API-first approach. Recommends LeadMagic for API/automation workflows, Apollo for teams wanting prospecting + outbound in one tool. Result: Clear comparison with cost analysis and recommendation.

Troubleshooting

Email Finder returning null for many lookups

Symptom: Email Finder returns null (not_found) for 40%+ of lookups. Cause: Input data quality issues — misspelled names, wrong company domains, people no longer at that company. Solution: Validate company domains first with Company Search. Use LinkedIn URLs with Profile to Email for higher hit rates. For stale lists, run Job Change Detector first to identify who's moved. Combine with other providers (via Clay waterfall) for maximum coverage.

Credits running out faster than expected

Symptom: Credit balance depleting before the billing cycle ends. Cause: High-cost endpoints (Mobile Finder at 5 credits, Email to Profile at 10 credits) or ad search returning many results (1 credit per ad). Solution: Audit endpoint usage in your dashboard. Favor low-cost endpoints (Email Finder at 1 credit, Employee Finder at 0.05 credits) where possible. Upgrade to Essential+ for credit rollover. Use Email Validation (0.25 credits) to pre-filter before running expensive lookups.

MCP server not connecting

Symptom: LeadMagic tools not appearing in Claude Code or Cursor after MCP setup. Cause: API key not set in environment, or MCP config syntax error. Solution: Verify LEADMAGIC_API_KEY is set in your environment or MCP config. Test the API key with curl https://api.leadmagic.io/v1/credits -H "X-API-Key: your_key" — should return your balance. Check MCP config JSON syntax. Restart your editor after config changes.
