Get Cost Over Time

 
 - `limit: optional number`
 
-  Maximum number of time buckets per page. Defaults and caps vary by bucket_width (1d: default 7, max 31; 1h: default 24, max 168; 1m: default 60, max 256).

-- `products: optional array of string`
+- `products: optional array of "chat" or "claude-tag" or "claude_code" or 4 more`
 
-  Product surfaces to include. Defaults to all products. Use `group_by[]=product` to break out per-product values. Values include "chat", "claude_code", "cowork", "office_agent", "claude_in_chrome", "claude_design", and "claude-in-slack". "claude-in-slack" (with hyphens) is Claude Tag, the Claude product in Slack. A similarly spelled legacy value (underscores instead of hyphens) identifies the retiring v1 Slack chat bot and appears only for organizations that used it.

 - `rbac_group_ids: optional array of string`
 
   Filter to usage attributed to specific RBAC groups. Accepts tagged RBAC group IDs (`rbac_group_...`) or bare group UUIDs. A row matches when the user belonged to any of the listed groups on the (UTC) day the usage occurred; usage with no group attribution never matches.

 
       - `model: string or null`
 
-        Model that produced the usage or cost, as a model name in the form the `models[]` filter accepts (for example, `claude-opus-4-6`). Null unless `model` is in `group_by[]`; it can also be null on grouped rows whose usage or cost is not attributed to a specific model, such as code execution.

       - `product: string or null`

       - `rbac_group_id: string or null`
 
-        RBAC group (team) the usage is attributed to, in the public tagged `rbac_group_...` spelling — the same spelling the activity resources use for this key, so the same team has ONE id across resources and it round-trips as an `rbac_group_ids[]` filter value. Populated only when `rbac_group_id` is in `group_by[]`. Any-membership semantics: a user in several groups contributes their full usage to each of those groups' rows, so the named-group rows overlap and their sum can exceed the org total. A null value is the single unassigned row: users in no group on that (UTC) day. For the true org total, run the same query with no group_by.
