Endgame

Endgame (Endgame Labs, Inc.) is a context graph platform for go-to-market teams and AI agents that turns sales calls, CRM records, emails, Slack conversations, meeting transcripts, and uploaded documents into structured, queryable revenue intelligence. Sales and RevOps users ask questions across their book of business in natural language, and connected AI assistants reach the same knowledge through the Endgame MCP Server. The public REST API (rooted at /api/v1) lets developers create and manage Endgame threads programmatically over HTTPS with Bearer-token authentication, while a broad connector surface ingests context from Salesforce, Gong, Chorus, Clari Copilot, Zoom, Notion, Confluence, Highspot, Seismic, Snowflake, Slack, Microsoft Teams/SharePoint/Outlook, and Google Drive. Endgame was surfaced through the API Evangelist VC-portfolio pipeline and has been enriched from its published developer documentation, OpenAPI, MCP server, and trust/security programs.

Endgame publishes 1 API on the APIs.io network: Threads API. Tagged areas include Company, Sales, Revenue Intelligence, Go-To-Market, and Artificial Intelligence.

Endgame’s developer surface includes authentication, documentation, API reference, getting-started guide, changelog, support, engineering blog, and 25 more developer resources.
