API & MCP documentation

One key powers the REST API and the MCP server β€” same data, same credit wallet. Search is free; you only pay on reveal.

Quickstart

Base URL

https://leaderra.ai/api

Authentication β€” pass your key in the header (get one in API & MCP):

curl https://leaderra.ai/api/v1/search \
  -H 'X-API-Key: lk_live_…' \
  -H 'Content-Type: application/json' \
  -d '{ "offer": "…", "icp": "…", "count": 25 }'

MCP server

Drop Leaderra into Claude, Cursor, or any MCP client. Ask in natural language β€” β€œFind VP Customer Success at SaaS companies hiring CSMs” β€” and your agent calls the tools below.

MCP config

{
  "mcpServers": {
    "leaderra": {
      "url": "https://leaderra.ai/api/mcp",
      "headers": { "x-leaderra-key": "lk_live_…" }
    }
  }
}
leaderra_searchFind scored hot-signal leads from a prompt or filters (free).
leaderra_revealReveal email / mobile / company+person / analysis for a record.
leaderra_signalsJob-change, hiring and ad-spend signals for a saved record/company.
leaderra_creditsCheck the credit balance and plan.

Every REST capability has an MCP tool and vice-versa β€” the two surfaces stay in sync.
