LatestRounds API

Getting started

LatestRounds is a GTM trigger layer — funding closes, your stack reacts. Use the REST API, MCP server, or webhook polling to pipe enriched funding data into your CRM, enrichment tool, or AI assistant.

Generate a key from your API dashboard. Every request requires it in the Authorization header.

Keep your key server-side only. Never expose it in client-side code or public repos.

Fetch the latest seed rounds in the US. Each record returned costs 1 credit.

curl -s "https://latestrounds.com/api/v1/funding/latest?limit=5&country=US&stage=seed" \
  -H "Authorization: Bearer YOUR_API_KEY"

Add this to your .mcp.json to query funding data in natural language inside Claude, Cursor, or any MCP-compatible AI client. No SQL, no endpoints to memorize.

{
  "mcpServers": {
    "latestrounds": {
      "command": "npx",
      "args": ["-y", "latestrounds-mcp@latest", "--api-key", "YOUR_API_KEY"]
    }
  }
}

MCP calls consume the same credits as direct API calls. Full MCP setup guide →

Poll the funding feed on a daily schedule, filter against your ICP, and push matches into your CRM or outreach tool. A round closes → your sequence fires — all within hours.

// Poll daily — new seed rounds in the US
const res = await fetch("https://latestrounds.com/api/v1/funding/latest?stage=seed&country=US&from=TODAY", {
  headers: { Authorization: "Bearer YOUR_API_KEY" }
});
const { data } = await res.json();

// Filter against your ICP, push matches to your CRM
for (const round of data) {
  if (matchesICP(round)) await pushToCRM(round);
}
