What platforms does LeadMagic support?

LeadMagic is available on Web App and Browser extension.

What are the limitations of LeadMagic?

No free tier: the cheapest self-serve plan is $99 per month, which prices out casual testing. It is an enrichment layer, not a prospecting app, so teams without Clay or a sequencer get little from it. Monthly credit wallets have a cap of twice the total, and excess credits expire.

What is LeadMagic?

LeadMagic is an API-first B2B enrichment service for verified work emails, direct mobiles, company data and hiring signals. It runs through REST, CLI and an MCP server for AI agents, plugs into Clay, Smartlead, Instantly and Zapier, and does not charge credits for failed lookups.

LeadMagic is a B2B data enrichment service that fills gaps in lead records with verified work emails, direct mobile numbers, company profiles, hiring signals and buying intent. It is aimed at sales teams, outbound agencies and GTM engineers who already run prospecting inside tools like Clay, Smartlead, Instantly, Apollo or Zapier, and who need cleaner records pushed into those workflows rather than another database to manage. The product is delivered as a set of REST endpoints, a command line interface and a hosted MCP server, all sharing one account and one credit balance. Core endpoints cover email finding and validation, mobile finding, personal email lookup, company enrichment and profile search. Bulk search runs against a claimed 400M+ people profiles, 25M+ companies and 46M+ open job postings, filterable by title, seniority, geography and firmographics. Catch-all validation is a stated strength: the vendor publishes a case study where a competitor flagged 73 of 500 positive replies as catch-all while LeadMagic resolved nearly all of them. In practice, a team either uploads a CSV, calls the API from its own pipeline, or connects the MCP server to an AI client such as Claude or Cursor so an agent can request a contact and receive a verified record mid-conversation. Failed lookups and not-found results do not consume credits, which makes trial-and-error enrichment cheaper than metered competitors that bill per attempt. Rate limits are published per endpoint, with the main finder and validation tools set at 600 requests per minute. The trade-off is that LeadMagic is infrastructure, not a finished prospecting app. There is no self-serve free tier, entry pricing starts at $99 per month, and real value depends on wiring the endpoints into a sequencer, spreadsheet or agent. Teams wanting an all-in-one contact database with a UI will find it thinner; teams that already own their stack get a focused enrichment layer.

How do you use LeadMagic?

1Create an account and generate an API key
Sign up, choose a plan and open the API settings to issue a key. One key works across every endpoint, and the same account carries the CLI and MCP access.
2Read the API reference and pick your endpoints
The v1 introduction lists the available endpoints and their request shapes. Start with email finder and validation, then add mobile or company enrichment as needed.
3Enrich a list without writing code
Upload a CSV to resolve emails, phones and company fields in bulk. Failed matches are skipped rather than billed, so a messy list is safe to run.
4Wire enrichment into your existing stack
Add LeadMagic as an enrichment step inside Clay, Smartlead, Instantly or Zapier, or call the REST endpoints directly from your own pipeline.
5Connect the MCP server to an AI client
Point Claude, Cursor or another MCP-compatible client at mcp.leadmagic.io/mcp and authorize with OAuth. Agents can then call people and email tools live while answering a prompt.
6Protect deliverability with validation
Run prospect lists through email validation before sending. Definitive valid and invalid results are billed; unknown results are free, so catch-all domains can be retried.

Pros and cons

Pros

Failed lookups and not-found results do not consume credits, so bad data does not eat the budgetAI
One credit pool and one API key across email, mobile, company, search and validation endpointsAI
MCP server lets Claude, Cursor and other AI clients call live enrichment tools during a conversationAI
Catch-all resolution recovers leads that stricter validators discard, per a published head-to-head case studyAI
Bulk CSV and CLI paths give non-developers a way in without building an integration firstAI

Cons

No free tier: the cheapest self-serve plan is $99 per month, which prices out casual testingAI
It is an enrichment layer, not a prospecting app, so teams without Clay or a sequencer get little from itAI
Monthly credit wallets have a cap of twice the total, and excess credits expireAI
Most of the 600 requests per minute limits are fixed on every self-serve plan, so heavy throughput requires a custom dealAI
GDPR compliance is left to the customer; the vendor supplies a DPA and suppression handling but not a legal basisAI
