One API · eight tools

Four kinds of data. One call away.

search_people

Find the people

Title, function, seniority, location, company size, tech and industry. Every result says why it matched.

search_companies · enrich_company

Map the companies

Domain, headcount band, industry, stack and the signals that make an account worth a message today.

enrich_person · verify_email

Verified work emails

A verification waterfall on every address. Catch-all and unknown are labelled as what they are, never as "valid."

scrape_jobs · scrape_company

Hiring and web signals

Turn a careers page or homepage into structured facts: open roles, products, pricing, positioning.

Records with receipts

Every record says why it's here and how fresh it is.

Most databases hand your agent a row and hope. Leadsets returns match reasons, verification status, confidence and the date each field was last checked, so the agent (and you) can decide what to trust.

  • Match reasons on every result
  • Field-level checked_at and verified_at
  • Source and data-rights metadata, plus opt-out honoured

How it works

First useful result in under five minutes.

  1. 1

    Connect your agent

    Add the remote MCP server to Claude, Cursor or any MCP client. Or call the REST API with your key.

    https://mcp.leadsets.ai
  2. 2

    Describe your customer

    In plain language. The agent turns it into filters and picks the right tools: search, enrich, verify, scrape.

    "RevOps leads at 50–200 person fintechs"
  3. 3

    Use the list anywhere

    Push to your sequencer, CRM or sheet. Structured JSON with receipts, never a locked dashboard.

Questions, answered straight.

What does "unlimited" actually mean?

No credits and no per-record bill. Search and enrichment each have fair-use limits per five hours and per week, shown on the pricing page and returned by every API response. Records only count when data comes back. Normal use never hits the limits; bulk database extraction does.

Where does the data come from?

Licensed suppliers and permitted public sources, normalized into our own index. Every field carries its source and the date it was last checked.

How accurate are the emails?

Every email runs through a verification waterfall and comes back as verified, catch-all, unknown or invalid. We publish our benchmark method. No provider can honestly promise 100%, and we don't.

Do I need Claude to use it?

No. The MCP server works with any MCP client, and everything is also a REST endpoint with TypeScript and Python SDKs.

Can someone ask to be removed?

Yes. Anyone can opt out at leadsets.ai/opt-out, and suppressed records are never served again.

Let your agent do the list building.
