Create and manage Endgame threads over a standard HTTPS REST API.
Open Beta: The Endgame REST API is expected to continue evolving, and its
endpoints may change.
The Endgame REST API lets you create and manage threads — the same
conversational units that power Endgame Chat — from any HTTP client. Start a
thread with a prompt, poll it for the assistant’s response, rename it, list
an organization’s threads, or delete one. Use it to embed Endgame directly
into your own applications, agents, or back-office automations.
Authenticate with a user-scoped API key and POST a prompt to /threads.
The prompt is required — it’s persisted as the first user message and
triggers an assistant response that generates asynchronously. You get back
the thread plus the IDs of both messages:
curl -X POST https://app.endgame.io/api/v1/threads \ -H "Authorization: Bearer eak_your_api_key_here" \ -H "Content-Type: application/json" \ -d '{"prompt": "What accounts does my team own?"}'
The response includes the thread, every message on it, and a derived status
object (idle, in_progress, or error) you can poll until the assistant
finishes.
