The demo endpoint uses a fixed max token limit of 1024 and does not support streaming. For full chat capabilities, use the AI chat endpoint with a subscription plan.

Every successful demo chat request automatically logs token usage and cost to the usage tracking system. Demo requests are recorded with userId: "demo" and agentId: "demo-chat", and are visible in the cost dashboard.
