Get Per-User Cost

GET/v1/organizations/analytics/user_cost_report

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

Returns cost per user, ranked by spend; group_by[] or bucket_width splits a user across several rows. Use this to see which users account for the most cost. Only cost attributed to a user account is included; cost with no user attributed to it, such as Code Review usage and Claude Tag usage in Slack channels, is left out. Available to organizations on a Claude Enterprise plan. Requires an API key with the read:analytics scope.

This endpoint is one of the legacy Claude Enterprise usage and cost reports. For new integrations, use GET /v1/organizations/analytics/cost in the Usage and Cost Analytics API instead. To move an existing integration, see Migrate from the Claude Enterprise usage and cost reports.

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"
claude_tag_categories: optional array of BetaAnalyticsClaudeTagCategory

Filter to Claude Tag (Claude in Slack) usage in specific spend categories. Usage with no category never matches. dm usage is reported under the user's product rather than claude-tag, so combining this filter with products[]=claude-tag excludes it. Use group_by[]=claude_tag_category to break out per-category values.

maxItems100
One of the following:
"dm"
"engaged"
"monitoring"
"proactive"
"scheduled"
claude_tag_user_ids: optional array of string

Filter to Claude Tag (Claude in Slack) usage attributed to specific Slack users, by Slack user ID (for example U0123ABCDEF), not claude.ai user ID. Usage that is not Claude Tag, and Claude Tag usage not attributed to a single user, never matches. Use group_by[]=claude_tag_user_id to break out per-user values.

maxItems100
context_windows: optional array of BetaAnalyticsContextWindow

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 "claude_tag_category" or "claude_tag_user_id" or "context_window" or 8 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:
"claude_tag_category"
"claude_tag_user_id"
"context_window"
"cost_type"
"inference_geo"
"model"
"product"
"rbac_group_id"
"slack_channel_id"
"speed"
"token_type"
inference_geos: optional array of BetaAnalyticsInferenceGeoFilter

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
minimum1
maximum1000
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 BetaAnalyticsProductFilter

Product surfaces to include. Defaults to all products.

maxItems100
One of the following:
"chat"
"chat_cowork_unified"
"claude-tag"
"claude_code"
"claude_design"
"claude_in_chrome"
"cowork"
"office_agent"
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
Headers
"anthropic-version": optional string

The version of the Claude API you want to use.

Returns
data: array of BetaAnalyticsCostUsersItem { actor, amount, claude_tag_category, 15 more }

Rows for this page, ranked by order_by in the order direction. One row per user, or several per user when group_by[] or bucket_width breaks that user's usage or cost out across rows. Rows split out by cost_type or token_type (cost endpoint only) stay adjacent and are ranked as one unit.

actor: BetaAnalyticsUserActor { type: "user_actor", deleted, email_address, 2 more }

The user this row's usage or cost is attributed to. Always a user_actor.

type: "user_actor"

Actor type. Always "user_actor".

deleted: boolean

True when the account has been deleted, or when the user is no longer a member of the organization or its associated organizations (for example, their membership was removed or they were deprovisioned via your identity provider). email_address stays populated for removed users and is null when the account has been deleted. name follows the rules described on that field. The user_id is still populated for reconciliation.

email_address: string or null

The user's email address, including for users who are no longer members of the organization or its associated organizations. Null when the account has been deleted (check deleted) and for system-minted service accounts, which have no person's mailbox behind them (check name).

name: string or null

The user's full name. Null when the user has not set a name. Returns "Deleted User" when the account itself has been deleted, or when the user is no longer a member of the organization or its associated organizations and the organization has chosen to hide the names of removed users. Otherwise, the name stays populated for removed users. Rows for system-minted service accounts render the service name (for example, "Claude Security" for usage by Anthropic's security-patching service) or null.

user_id: string

Tagged user ID.

amount: string

Amount (post-discount, pre-credit) in fractional cents (minor units).

claude_tag_category: BetaAnalyticsClaudeTagCategory or null

Claude Tag (Claude in Slack) spend category: engaged (a person addressed Claude in a channel or thread), proactive (Claude responded without being addressed), scheduled (a scheduled routine ran), monitoring (Claude watching a channel it was asked to monitor), or dm (direct messages with Claude). Populated only when claude_tag_category is in group_by[]; null for usage that is not Claude Tag. Direct-message usage is billed to the individual user and is reported under that user's product, not under claude-tag. New categories may be added over time.

One of the following:
"dm"
"engaged"
"monitoring"
"proactive"
"scheduled"
claude_tag_user_id: string or null

Slack user ID (for example U0123ABCDEF) of the member the Claude Tag (Claude in Slack) usage is attributed to, not a claude.ai user ID. Populated only when claude_tag_user_id is in group_by[]; null for usage that is not Claude Tag and for Claude Tag usage that is not attributed to a single user (for example monitoring, and proactive usage Claude initiated), so per-user rows can sum to less than the Claude Tag total. Cannot be combined with group_by[]=rbac_group_id or the rbac_group_ids[] filter.

context_window: BetaAnalyticsContextWindow or null

Context-window pricing tier of the usage or cost. Null unless context_window is in group_by[]; it can also be null on grouped rows with no context-window tier, such as code execution.

One of the following:
"0-200k"
"200k-1M"
cost_type: BetaAnalyticsCostType or null

Cost component breakdown; null when returning the combined total.

One of the following:
"code_execution"
"tokens"
currency: string

Currency code for the cost amount. Currently always "USD".

defaultUSD
ending_at: string or null

End of the row's UTC time bucket (exclusive), as an RFC 3339 timestamp; equal to starting_at plus one bucket_width. Null unless bucket_width is set.

formatdate-time
inference_geo: "global" or "us" or null

Inference region of the usage or cost. Null unless inference_geo is in group_by[]; it can also be null on grouped rows where the region is not set (the rows that inference_geos[]=not_available matches).

One of the following:
"global"
"us"
list_amount: string

List-price amount (pre-discount) in fractional cents.

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-5-5). 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

Product surface that produced the usage or cost. Null unless product is in group_by[]; it can also be null on grouped rows whose usage cannot be attributed to a known surface. Values include chat, claude_code, cowork, office_agent, claude_in_chrome, claude_design, claude-tag, and chat_cowork_unified. claude-tag is Claude Tag, the Claude product in Slack. chat_cowork_unified is Chat and Cowork unified, Cowork's features inside claude.ai chat: chat and Cowork usage by a member who has it turned on is reported under this value instead of chat or cowork. It is accepted as a filter only on deployments that offer Chat and Cowork unified. Some unattributed usage is reported as "other".

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 without group_by[].

requests: number or null

Number of API requests in this row's scope. Null when group_by includes cost_type or token_type (the count has no per-component attribution; read it from the ungrouped response). For sandbox / code-execution events, this counts execution spans rather than HTTP requests (these rows surface with product: null).

slack_channel_id: string or null

Slack channel the usage originated from. Populated only when slack_channel_id is in group_by[]; null for usage outside Slack (and for rows recorded before channel attribution was enabled).

speed: "fast" or "standard" or null

Inference speed mode of the usage or cost: fast or standard. Null unless speed is in group_by[].

One of the following:
"fast"
"standard"
starting_at: string or null

Start of the row's UTC time bucket (inclusive), as an RFC 3339 timestamp. Null unless bucket_width is set; without bucket_width, each row aggregates the full requested range.

formatdate-time
token_type: BetaAnalyticsTokenType or null

Token type when cost_type is tokens; null otherwise.

One of the following:
"cache_creation.ephemeral_1h_input_tokens"
"cache_creation.ephemeral_5m_input_tokens"
"cache_read_input_tokens"
"output_tokens"
"uncached_input_tokens"
data_refreshed_at: string or null

RFC 3339 timestamp of the export this response was served from. Null when no export yet covers any part of the requested range, in which case data is empty. Data beyond this watermark is incomplete; for stable results, set ending_at to this value or earlier. Data is typically refreshed every 4 hours. Values can be revised as late events arrive and reconciliation runs, until about 7 days after the end of the calendar month the usage falls in; for example, values for October 1 can change until about November 7.

formatdate-time
has_more: boolean

Whether another page is available. When true, pass next_page as the page parameter to fetch it.

next_page: string or null

Opaque cursor for the next page, or null when has_more is false. Pass it as the page parameter, keeping the other parameters unchanged. A cursor can expire after the underlying data refreshes; the request then returns HTTP 410 and pagination must restart from the first page.

organization_id: string

ID of the Organization.
