Company funding data API

company_funding

2.5 credits / company returned

Fetch one company's funding profile from the funding index: total raised, number of rounds, last round type and date, investor names, IPO / operating status, stock symbol and founded date. Address the company by org_id (from resolve_company), domain, or name. has_funding_data is false when the company has no profile in the funding index (~40% coverage of the company index).

Call it from your agent (MCP)

Connect once and company_funding appears in your agent’s toolbox next to every other gtm.dev tool. Claude Code:

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

Under the hood, the client sends:

curl -X POST https://mcp.gtm.dev \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call",
       "params":{"name":"company_funding","arguments":{"domain":"hubspot.com"}}}'

other clients (cursor, claude desktop, openai agents sdk, langchain): mcp setup

Call it over REST

curl -X POST https://api.gtm.dev/v1/tools/company_funding \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain":"hubspot.com"}'

Errors (401, 402, 429, 400) are listed in the REST reference. Calls that error are not billed — see pricing.
