3535- `filter: optional array of string`
3636
37 Filters as `dimension:value`, e.g. `filter[]=rbac_group_id:{id}`. Repeat the param for OR within a dimension and across dimensions for AND. Supported dimensions on this endpoint: `product`, `rbac_group_id`, `share_status`, `skill_name`, `user_id`. Value forms: `product` is one of `chat`, `claude_code`, `cowork`, or `office_agent`; `rbac_group_id` takes the tagged id (`rbac_group_...`, as emitted in responses and by the spend-limits API) or a bare group UUID, and matches users who held the group at any point during each covered UTC day (time-of-usage attribution); `share_status` is one of `organization`, `private`, or `public`; `skill_name` matches case-insensitively; `user_id` takes a tagged user id (`user_...`), as emitted in responses. An unsupported dimension returns 400. At most 100 entries.

An unsupported dimension returns 400. At most 100 entries. `chat_cowork_unified` is accepted as a `product` value only on deployments that offer Chat and Cowork unified.

143143 List-price (rate-card) value of the member requests attributed to this skill, as a decimal string in the minor unit of `currency` (cents for USD), from Claude Code, Cowork, and Office Agent request-level attribution — the value of requests that involved the skill, not the skill's incremental cost. Unlike `estimated_overage_spend` this reflects usage value regardless of how it was funded — seat-covered usage counts — but it is undiscounted and does not tie to billed spend or the organization's spend reporting. claude.ai chat usage carries no request-level attribution and contributes nothing: the field is null on `chat` product rows and on `office_agent` product cuts dated before 2026-06-18 (the Office Agent attribution data-start), and on ungrouped rows it covers the Claude Code + Cowork + Office Agent share only (null when no attributable usage exists). Also null under the same conditions as `estimated_overage_spend` (spend reporting not enabled for this organization, `office_agent` product cuts before the 2026-06-18 data-start). "0" means attributable usage existed but none was attributed to this skill. Addable across days: date-range rollup mode returns the window's sum. On `group_by[]` and `filter[]` shapes both amounts can total below the ungrouped value for the same skill over the same date or range: spend attributed to a member–skill pair with no counted usage on that day is excluded from those cuts.

145 - `chat_cowork_unified_metrics: optional object or null`
146
147 Skill use recorded while members had Chat and Cowork unified (Cowork's features inside claude.ai chat) turned on, split into chat conversations and Cowork sessions. A count is null in date-range mode where it cannot be computed. Omitted from the response on deployments that do not offer Chat and Cowork unified.

149 - `chat: BetaAnalyticsSkillChatCoworkUnifiedChatMetrics`
150
151 A skill's use in chat conversations recorded while members had
152 Chat and Cowork unified turned on.
153
154 - `distinct_conversation_skill_used_count: number or null`
155
156 Same measure as `chat_metrics.distinct_conversation_skill_used_count`, for activity recorded while members had Chat and Cowork unified turned on. Approximate (HLL, typical error <2%) in date-range mode. Null on aggregated rows where a distinct count cannot be computed.
157
158 - `sessions: BetaAnalyticsSkillChatCoworkUnifiedSessionsMetrics`
159
160 A skill's use in Cowork sessions recorded while members had Chat
161 and Cowork unified turned on.
162
163 - `distinct_session_skill_used_count: number or null`
164
165 Same measure as `cowork_metrics.distinct_session_skill_used_count`, for activity recorded while members had Chat and Cowork unified turned on. Approximate (HLL, typical error <2%) in date-range mode. Null on aggregated rows where a distinct count cannot be computed.
166
145167 - `currency: optional string or null`
146168
147169 Currency for this row's monetary fields (`estimated_overage_spend` and `attributed_list_price`), as an uppercase ISO-4217 code. Always "USD" when either amount is populated; null whenever both amounts are null.

163 Product that produced this row's activity: one of `chat`, `claude_code`, `cowork`, or `office_agent` (the canonical Cost & Usage product naming; an `office_agent` row's per-surface breakdown is in its `office_metrics`). On `/plugins` only `cowork` and `claude_code` occur (the only surfaces with plugin attribution); on `/artifacts` only `chat`, `claude_code`, and `cowork` occur (the surfaces that create artifacts); `/apps/chat/projects` does not support the product dimension (a `product` entry in `group_by[]` or `filter[]` there is rejected). Present only when the request grouped by `product`.
