Get Per-User Cost

GET/v1/organizations/analytics/user_cost_report

Get per-user cost in USD across a date range.

Returns one row per user, ranked by spend. Use this to see which users account for the most cost. Only cost attributable to a seat user is included; for organization-wide totals including direct API-key and automation traffic, use the bucketed /v1/organizations/analytics/cost_report endpoint. Available to organizations on a Claude Enterprise plan. Requires an API key with the read:analytics scope.

Query parameters

starting_at: string

Start of range, inclusive. RFC 3339 tz-aware. Must be within the last 365 days and no earlier than 2026-01-01T00:00:00Z.

formatdate-time

bucket_width: optional "1d" or "1h" or "1m"

Time-bucket granularity. When set, each row's starting_at and ending_at are populated and one actor may span several rows (one per time bucket with usage). The time bucket counts toward limit, so one page can return multiple rows for the same actor. ending_at is required when bucket_width is set, and with bucket_width="1m" the range may span at most 24 hours. When omitted, each row aggregates the full [starting_at, ending_at) range.

One of the following:

"1d"

"1h"

"1m"

context_windows: optional array of "0-200k" or "200k-1M"

Filter to specific context-window pricing tiers. Use group_by[]=context_window to break out per-tier values.

maxItems100

One of the following:

"0-200k"

"200k-1M"

ending_at: optional string

End of range, exclusive. When omitted, defaults to the earlier of now and starting_at + 31 days. The range may span at most 31 days.

formatdate-time

exclude_deleted_users: optional boolean

If true, omit rows for users who are deleted (deleted: true). A page may contain fewer than limit rows; use has_more and next_page to paginate as usual.

defaultfalse

group_by: optional array of "context_window" or "cost_type" or "inference_geo" or 6 more

Break each actor's row out by the given dimensions. Accepts the same values as the bucketed /cost_report endpoint. The product, model, context_window, inference_geo, and speed dimensions — and the time bucket, when bucket_width is set — count toward limit. cost_type and token_type do not: cost_type returns one row per cost component (tokens, web search, code execution); token_type returns one row per token type, each with cost_type: "tokens"; combining both returns the per-token-type rows plus the web-search and code-execution rows. A page can therefore contain more rows than limit when cost_type or token_type is requested.

maxItems100

One of the following:

"context_window"

"cost_type"

"inference_geo"

"model"

"product"

"rbac_group_id"

"slack_channel_id"

"speed"

"token_type"

inference_geos: optional array of "global" or "not_available" or "us"

Filter to specific inference regions. not_available matches rows where the region is unset. Use group_by[]=inference_geo to break out per-region values.

maxItems100

One of the following:

"global"

"not_available"

"us"

limit: optional number

Number of rows per page (1-1000, default 20). One row per actor unless group_by[] or bucket_width splits an actor across rows; cost_type/token_type fan-out rows (cost endpoint only) are the exception — they do not count toward this limit, so data can exceed it.

default20

maximum1000

minimum1

models: optional array of string

Models to include. Defaults to all models. Use group_by[]=model to break out per-model values.

maxItems100

order: optional "asc" or "desc"

Sort direction. Defaults to desc.

defaultdesc

One of the following:

"asc"

"desc"

order_by: optional "amount" or "list_amount"

Metric to rank actors by. Defaults to amount.

defaultamount

One of the following:

"amount"

"list_amount"

page: optional string

Opaque cursor from a previous response's next_page field.

products: optional array of string

Product surfaces to include. Defaults to all products. 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.

maxItems100

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.

maxItems100

slack_channel_ids: optional array of string

Filter to usage originating from specific Slack channels. Use group_by[]=slack_channel_id to break out per-channel values.

maxItems100

speeds: optional array of "fast" or "standard"

Filter to fast or standard inference mode. Use group_by[]=speed to break out per-mode values.

maxItems100

One of the following:

"fast"

"standard"

user_ids: optional array of string

Filter to specific users by tagged user ID.

maxItems100
