How do I authenticate?

Pass your API key via the X-API-Key header. Sign up at app.leadmagic.io to get one — it takes 30 seconds, no credit card required.

What are the rate limits?

Default rate limits are generous and scale with your plan. We support burst traffic and high-concurrency use cases. Contact us for custom limits.

Do I pay for failed lookups?

No. You only pay for valid, verified results. Invalid lookups are on us — no credits deducted, no questions asked.

What integrations are supported?

Native integrations with Clay, Apollo, Instantly, Smartlead, Bitscale, Salesforge, Zapier, Make, and more. Plus MCP support for Cursor, Claude, VS Code, Windsurf, and other AI clients.

Is there a free tier?

Yes — LeadMagic features an onboarding Milestones Program (Activation Hub) where you can earn up to 205 free credits by completing simple setup tasks (like issuing an API key, making your first API call, and uploading your first CSV list). No credit card is required to start. If you sign up with a personal email (like Gmail), your earned credits are placed in 'pending' status and unlock instantly when you add a payment method or switch to a business email.

Is LeadMagic GDPR compliant?

LeadMagic is designed to support applicable GDPR and CCPA/CPRA obligations for B2B data use cases. We source business data from public and licensed sources and provide data subject rights and suppression request workflows.
