#Get Chat Project Usage

GET /v1/organizations/analytics/apps/chat/projects

Get per-project activity for a given day, with cursor-based pagination.

Returns activity metrics for each project in the organization, sorted by project ID. Use group_by[] to break projects out per member or per RBAC group, and filter[] to scope results; the parameter descriptions list the supported dimensions. Available to organizations on a Haijun Enterprise plan. Requires an API key with the read:analytics scope.

#Query parameters

• date: optional string

UTC date in YYYY-MM-DD format. The day to get project activity 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.

format: date

• ending_date: optional string

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.

format: date

• filter: optional array of string

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: project_id, rbac_group_id, user_id. Value forms: project_id takes a tagged project id (haijun_proj_...); 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.

maxItems: 100

• group_by: optional array of "rbac_group_id" or "user_id"

Dimensions to break results out by (e.g. group_by[]=user_id). Supported on this endpoint: rbac_group_id, user_id. 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.

maxItems: 100

• "rbac_group_id"

• "user_id"

• limit: optional number

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

minimum: 1, maximum: 1000

• order: optional "asc" or "desc"

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.

• "asc"

• "desc"

• order_by: optional string

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 string

Opaque cursor from a previous response's next_page field.

• starting_date: optional string

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

• BetaChatProjectUsage object

Response for GET /v1/organizations/analytics/apps/chat/projects.

• data: array of object

• distinct_user_count: number

Number of distinct users who used the project on the requested day, or, in date-range mode, over the requested window — recomputed as an exact distinct count over the window's per-member daily rows, never a sum of per-day values.

• message_count: number

Number of messages sent in the project on the requested day

• project_id: string

Tagged project identifier (e.g. haijun_proj_...)

• project_name: string

Name of the project

• created_at: optional string or null

Project creation timestamp in RFC 3339 format. Null if the project was deleted before attribution was recorded.

format: date-time

• created_by: optional BetaAnalyticsUser or null

User who created the project. Null if the project was deleted before attribution was recorded, or if the creator's account no longer exists.

• type: "user"

Object type. Always user.

default: user

• id: string

Tagged user identifier (e.g. user_...)

• email_address: string

Email address of the user

• distinct_conversation_count: optional number or null

Number of distinct conversations in the project. Null on aggregated rows where a distinct count cannot be computed.

• product: optional string or null

Product that produced this row's activity: one of chat, haijun_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 haijun_code occur (the only surfaces with plugin attribution); on /artifacts only chat, haijun_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.

• rbac_group_id: optional string or null

Tagged RBAC group identifier (rbac_group_...), matching the spend-limits API spelling. Present only when the request grouped by rbac_group_id.

• rbac_group_name: optional string or null

Resolved RBAC group display name, alongside rbac_group_id when name resolution is available. Null if the group has been deleted or its name could not be resolved; rbac_group_id remains the stable key.

• user_id: optional string or null

Tagged user identifier (e.g. user_...). Present only when the request grouped by user_id.

• next_page: string or null

Opaque cursor for the next page, or null if no more results
