AI demos are easy. AI products need infrastructure.

The shift from demo to product is where reliability, cost, user state, and maintenance start to matter. The first piece of that infrastructure is the thing that remembers what is happening — a session.

$ curl -X POST https://gateway.cerver.ai/v2/sessions \
    -H "Authorization: Bearer $CERVER_API_TOKEN"
→ { "session_id": "sess_a4f7c9...", "status": "ready" }

Free at hobby scale. Free for the agents you build on it.

That infrastructure starts with the session.

Yes, "session" sounds boring. So does plumbing. Nobody brags about pipes until the kitchen is underwater. The session is where memory, tools, compute, billing, recovery, and user state come together. Once it becomes important, it needs a clean interface your product and agents can depend on.

Cerver is the API for that layer.

Cerver gives you one interface for creating, running, switching, measuring, and closing AI sessions. But a good session layer should not only be reliable.

POST /v2/sessions
POST /v2/sessions/:id/run-llm
POST /v2/sessions/:id/compute
GET  /v2/sessions/:id/metrics
POST /v2/sessions/:id/close

Reliable is the baseline. Powerful is the point.

Cerver sessions are stable, transparent, and hard to accidentally break. They keep memory, tools, compute, billing, recovery, and user state together while your AI stack changes underneath. And they do more than hold state: they can switch models, move compute, track cost, recover runs, and spawn other sessions.
