Events
The ledger itself, in three views:Cost
Spend for the time range: total and trend over time, plus the top models, agents, and users by cost — the fastest way to answer “what changed in the bill”.Dimensions
Each dimension page aggregates the same ledger by one identifier:
Each page shows summary stats, top-N charts (by cost, calls, events, or duration), and a paginated table of every value in the dimension.
Dimension pages are only as rich as the context you send. Tag events with
userId, agentId, and threadId to light these pages up — see
Context.
