Quickstart

Get your key

Sign in at app.gtmrouter.dev — a one-time email link (or code), or Google. No passwords. Your workspace starts with 300 free credits. Create a key under API Keys; it is shown once and stored only as a hash.

Make your first call

Base URL https://api.gtmrouter.dev. Ask for fifty healthcare executives:

curl
curl https://api.gtmrouter.dev/v1/find_leads \
  -H "Authorization: Bearer YOUR_GTMROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "audience": "healthcare executives in the United States",
    "titles": ["Chief Executive Officer"],
    "industries": ["Hospitals and Health Care"],
    "limit": 50
  }'

Leads come back with full profiles and masked emails — chain each into enrich to reveal the verified address. That two-step is deliberate: you only pay to reveal contacts you actually want.

ℹ️ Every response carries a billing envelope. gtmrouter.credits_charged and credits_available disclose the exact cost of each call — misses are always free.

Or skip the HTTP — add the MCP server

Once you have a key, point any agent at the hosted MCP server and the whole loop becomes tools:

claude
claude mcp add --transport http gtmrouter https://mcp.gtmrouter.dev/mcp \
  --header "Authorization: Bearer YOUR_GTMROUTER_API_KEY"

Then just ask: “Find me 50 healthcare execs and draft an outbound campaign.” Anything that spends real money or sends real email pauses for your approval in the console — agents cannot purchase or launch on their own authority. Full setup for Claude, Cursor and n8n: Add to your agent.

Testing safely

  • Misses are free — a lookup that finds nothing charges nothing.
  • Use "limit": 2 while exploring find_leads.
  • Campaign drafts never send — launching is a separate, human-approved action.
  • A full test loop (find → enrich 3 → verify → draft) costs roughly 16 credits; your free 300 cover it many times over.
