LeadMagic turns cold prospect data into workflow-ready B2B intelligence. We're a bootstrapped company building the data layer that GTM engineers and AI agents reach for first — one API key, one billing surface, and three ways to call it.

 ┌──────────────────┐     ┌──────────────────┐     ┌──────────────────┐
 │  Your inputs     │ ──▶ │  LeadMagic API   │ ──▶ │  Workflow-ready  │
 │  names · domains │     │  REST · CLI · MCP│     │  verified data   │
 │  profile URLs    │     │  sub-200 ms      │     │  clean · current │
 └──────────────────┘     └──────────────────┘     └──────────────────┘

What you get: verified work emails, direct-dial mobile numbers, company firmographics, funding and hiring signals, B2B profile enrichment, and deliverability scoring — all pay-only-for-valid-results.

Pick the surface that fits your workflow. Every one of them reads from the same data layer and the same API key.

The hosted MCP at https://mcp.leadmagic.io/mcp speaks streamable HTTP and supports OAuth sign-in (with Dynamic Client Registration), a static public OAuth client, and API-key headers for locked-down environments. See mcp.leadmagic.io/clients for per-client install snippets — today we publish snippets for Cursor, Claude Desktop / Code / claude.ai, ChatGPT Developer Mode, VS Code / GitHub Copilot, Windsurf, Zed, Cline, Roo Code, OpenCode, Gemini CLI, JetBrains IDEs, Amazon Q, GitHub Copilot Coding Agent, Continue, Amp (Sourcegraph), Augment, and the Vercel AI SDK.

Every capability below is available through REST, CLI, and MCP. Full reference lives at leadmagic.io/docs.

Credit-based. 1 credit = 1 enrichment. You only pay for valid results, unused credits roll over, and there are no annual contracts. Start with 100 free credits — no credit card required. Full pricing lives at leadmagic.io/pricing.

LeadMagic ships first-class integrations with the tools GTM teams already use — and works inside any AI client that speaks MCP.

GTM and data platforms: Clay · Apollo · Instantly · Smartlead · Databar · Salesforge · n8n · Zapier · Make AI clients (via hosted MCP): Cursor · Claude · ChatGPT · VS Code / Copilot · Windsurf · Zed · OpenCode · Gemini CLI · and more

If you're wiring LeadMagic into a platform we don't list yet, the REST API is the same one everything else is built on — grab a key and go.

• Pay only for valid results. Credit-based billing, no charges for null lookups on the "free-if-not-found" endpoints.
• One API, every surface. The same data powers REST, CLI, MCP, and our partner integrations. One key to manage, one invoice to reconcile.
• Built for AI-native workflows. Hosted MCP with OAuth sign-in, per-client install snippets, and an official Cursor plugin that ships rules, skills, an enrichment agent, and commands together.
• Bootstrapped and customer-funded. No outside investors, no roadmap hostage to a board — the product moves where customers push it.
• GDPR-compliant data handling. See the FAQ on leadmagic.io for specifics, or reach security@leadmagic.io for a privacy/security questionnaire.

We publish a small set of public repos so you can read, audit, and vendor our integrations without guessing:

For SDK-level integrations (Node, Python, Go) and platform connectors, see the links in leadmagic.io/docs.

We take brand impersonation and supply-chain safety seriously. If someone publishes a "LeadMagic" skill, plugin, MCP server, or CLI from an owner that isn't github.com/LeadMagic, it is not from us — see the allow-list and reporting guidance in leadmagic-openapi/SECURITY.md.
