GET/v1/organizations/analytics/plugins

Get per-plugin install + invocation usage for a given day, with pagination.

Returns plugin usage metrics for the organization across Cowork and Claude Code, sorted by plugin name. The plugin_name value third-party is an aggregate bucket, not a plugin: it collects plugin activity, from either surface, for which the reporting client did not provide a plugin name — so an organization's own plugins can contribute both to their own named rows and to this bucket. Use group_by[] to break usage out per member, per RBAC group, or per product surface (Cowork / Claude Code), and filter[] to scope results; the parameter descriptions list the supported dimensions. Requires an API key with the read:analytics scope. starting_date / ending_date select range-rollup mode like /skills.

Parameters
date?:optional \Datetime⁠Query parameter

UTC date in YYYY-MM-DD format. The day to get plugin usage for. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day) and may be revised by a few percent over the following days. No earlier than 2026-01-01.

endingDate?:optional \Datetime⁠Query parameter

UTC date in YYYY-MM-DD format. End of the date range (exclusive); only valid with starting_date. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day), so this can be at most today — which is also the default when omitted, resolved once when the first page is served and reused for the rest of the pagination sequence. At most 366 days after starting_date.

filter?:optional list<string>⁠Query parameter

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: plugin_name, product, rbac_group_id, user_id. Value forms: plugin_name matches case-insensitively; product is chat_cowork_unified, claude_code, or cowork (the only surfaces with plugin attribution); 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); user_id takes a tagged user id (user_...), as emitted in responses. 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.

groupBy?:optional list<GroupBy>⁠Query parameter

Dimensions to break results out by (e.g. group_by[]=user_id). Supported on this endpoint: product, rbac_group_id, user_id. On this endpoint product takes the values chat_cowork_unified, claude_code, or cowork only (the surfaces with plugin attribution). Grouped rows carry the requested dimension values as additional fields and paginate like ungrouped responses via next_page; an unsupported dimension returns 400. rbac_group_id attributes a user to every group they held at any point during each covered UTC day, so grouped rows are not an exclusive partition and can sum above org-level totals. At most 100 entries.

limit?:optional int⁠Query parameter

Number of results per page (1-1000, default 100).

order?:optional Order⁠Query parameter

Sort direction: asc or desc. Defaults to asc for the endpoint's sort column and to desc when order_by names a metric (a top-N ranking). Applies to order_by, or to the endpoint's default sort field when order_by is omitted.

orderBy?:optional string⁠Query parameter

Sort field. Restricted to the endpoint's sort column plus its rankable metrics (metrics default to descending; a few metrics rank in date-range mode only, per the endpoint's documented orderable set).

page?:optional string⁠Query parameter

Opaque cursor from a previous response's next_page field.

startingDate?:optional \Datetime⁠Query parameter

UTC date in YYYY-MM-DD format. Start of a date range (inclusive). Enables rollup mode: one row per entity aggregated over the whole range — addable counters are summed across days, and a distinct count is never summed where summing could double-count (a field's range value is recomputed exactly over the window, approximate via HLL with typical error under 2%, null, or — for the creation-event counts, whose per-day values cannot overlap — a per-day sum that is itself exact; each field's own description says which). Use either date or starting_date, not both. Data is typically available with a 1-day lag (varies by query; the error for a too-recent date names the latest available day) and may be revised by a few percent over the following days. No earlier than 2026-01-01.

Returns
class AnalyticsPluginActivity { $claudeCodeMetrics; $coworkMetrics; $distinctUserCount; /* 9 more */ }
