LeadMagic

LeadMagic is an API-first B2B data platform that gives GTM engineers, AI agent builders, and outbound teams access to verified emails, mobile numbers, and company enrichment through a single REST API, CLI, and MCP interface.

Unlike traditional prospecting tools built around a UI, LeadMagic is designed to plug directly into your existing stack, whether that is a Clay waterfall, an AI agent running in Cursor or Claude, or a bulk CSV enrichment workflow.

Teams running technical outbound workflows at scale should look at this tool seriously, with plans starting at $49 per month for 2,000 credits.

Top Features

• REST API with 18 endpoints covering email, mobile, company, and profile data
• CLI and MCP access alongside the REST API, all from one API key
• Email finder with 97% accuracy and sub-200ms response times
• Mobile finder with claimed 300% higher coverage than standard providers
• Catch-all detection and deliverability scoring via dedicated validation endpoint
• Personal email finder for Gmail, Outlook, and iCloud when work emails bounce
• Intent signals via hiring data and ad spend intelligence
• Integrations with Clay, Apollo, ZoomInfo, Instantly, Smartlead, Zapier, Make, n8n, Salesforge, and AI tools including Cursor, Claude, and ChatGPT

Pricing

LeadMagic uses a credit-based model where 1 credit equals 1 enrichment and you only pay for valid results.

The Trial plan gives you 100 free credits with no credit card required.

Paid plans run from $49 per month for 2,000 credits at $0.0245 per credit, up to $99 per month for 5,000 credits, $249 per month for 20,000 credits, $499 per month for 50,000 credits, and $849 per month for 100,000 credits at $0.00849 per credit.

Unused credits roll over and there are no annual contracts required on any plan.

Who LeadMagic Is Built For

In practice, LeadMagic is not a point-and-click prospecting tool.

It is built for teams that want to own their data layer, not rent access to a platform's UI.

GTM engineers building Clay waterfalls, developers embedding enrichment into their own products, and AI agent builders who need real-time B2B data piped into Cursor or Claude are the primary audience here.

If your team does not have someone comfortable working with a REST API or building in Clay, this tool will feel underutilized.

For SDRs who want a simple interface to search and export leads, there are better-suited options in the market.

How LeadMagic Fits Into a Clay Workflow

LeadMagic positions itself as the data layer behind Clay waterfalls, and that is where it earns its keep.

The API connects directly to Clay tables, so you can run email finding, mobile lookups, and company enrichment as individual steps in a single automated workflow.

What this means for your outreach is that you can build a waterfall that tries LeadMagic first, then falls back to another provider, without switching tools or exporting CSVs between steps.

The 97% accuracy claim and sub-200ms response time matter here because slow or inaccurate enrichment steps create bottlenecks that compound across thousands of rows.

Teams already running Clay-to-Instantly or Clay-to-Smartlead workflows will find LeadMagic fits cleanly into that motion without requiring a separate login or manual export step.

LeadMagic for AI Agents and MCP

LeadMagic has built out 16 MCP tools specifically for AI agent environments like Cursor, Claude, and VS Code.

This is a meaningful differentiator from most B2B data providers, which are still UI-first and have not invested in agent-native access patterns.

In practice, this means a developer can give an AI coding agent access to real-time B2B data without writing custom API wrappers or managing authentication separately.

The key thing to know here is that MCP access uses the same API key as every other endpoint, so there is no additional setup or separate billing tier for agent use cases.

For teams building AI-assisted outbound workflows or internal sales tooling, this is a practical advantage over providers that require a human in the loop to pull data.

LeadMagic Credit Economics: What You Actually Pay Per Contact

The credit model charges differently depending on what you are pulling.

An email lookup costs one credit, but a mobile number lookup will consume more credits than an email lookup, which means your blended cost per contact rises when you need both.

At the Basic plan level, you are paying roughly $0.0245 per credit, which puts a single email find at about $0.025.

At the Professional tier with 50,000 credits per month, that drops to just under $0.01 per credit.

The rollover policy on unused credits is a genuine advantage for teams with variable monthly volume, since you are not penalized for a slow month the way you would be with a use-it-or-lose-it plan.

One thing to watch: the search data references older pricing tiers from third-party sources that differ from what LeadMagic currently shows on their site, so always verify current plan details directly before committing.

LeadMagic Accuracy and Deliverability Considerations

LeadMagic claims 97% email accuracy on their site, with SMTP validation and MX record checking built into the email finder response.

The API response includes a confidence score, email status, and both MX and SMTP validity flags, which gives you enough signal to make filtering decisions before anything hits your sending tool.

The catch-all validation endpoint is a separate call, which means you need to build that step explicitly into your workflow if you want to handle catch-all domains properly.

In outbound campaigns, catch-all domains are where most bounce problems originate, so skipping that step will hurt your sender reputation over time.

The personal email finder endpoint is a useful fallback for contacts where the work email bounces or cannot be found, covering Gmail, Outlook, and iCloud addresses.

LeadMagic vs. Traditional Prospecting Platforms

LeadMagic is not trying to replace Apollo or ZoomInfo as an all-in-one prospecting platform.

It has no built-in sequencing, no CRM, and no contact search UI in the traditional sense.

What it offers instead is a clean, developer-friendly data API that you can wire into whatever sequencing or CRM tool you already use.

If you are evaluating Apollo as an alternative, the comparison is not apples-to-apples: Apollo bundles sequencing and a contact database into one product, while LeadMagic is purely a data enrichment layer.

For teams that already have a sequencing tool like Instantly or Smartlead and just need reliable enrichment data, LeadMagic is a more focused and often cheaper option than paying for an all-in-one platform where half the features go unused.
