03 / HOW BILLING WORKS
What counts as usage?
Voxel bills on two dimensions: feature windows and streaming minutes.
Step 1
Create a session
POST /v1/sessions with ingestion_mode: "STREAMING". Receive a WebSocket URL.
Step 2
Ingest batches
Stream EEG sample arrays in real time. Each batch is timestamped with t0_unix_ms.
Step 3
Receive feature windows
Every second, a feature window publishes over WebSocket. Each window = 1 billable unit.
