• bucket_width: optional "1d"

  Time granularity of the response data.

  • "1d"

• ending_at: optional string

  Time buckets that end before this RFC 3339 timestamp will be returned.

• group_by: optional array of "workspace_id" or "description"

  Group by any subset of the available options.

  • "workspace_id"

  • "description"

• limit: optional number

  Maximum number of time buckets to return in the response.

• page: optional string

  Optionally set to the next_page token from the previous response.

Header Parameters

• "anthropic-beta": optional array of string

  Optional header to specify the beta version(s) you want to use.

  To use multiple betas, use a comma separated list like beta1,beta2 or specify the header multiple times for each beta.

Returns

• CostReport object { data, has_more, next_page }

  • data: array of object { ending_at, results, starting_at }

    • ending_at: string

      End of the time bucket (exclusive) in RFC 3339 format.

    • results: array of object { amount, context_window, cost_type, 7 more }

      List of cost items for this time bucket. There may be multiple items if one or more group_by[] parameters are specified.

      • amount: string

        Cost amount in lowest currency units (e.g. cents) as a decimal string. For example, "123.45" in "USD" represents $1.23.

      • context_window: "0-200k" or "200k-1M"

        Input context window used. null if not grouping by description or for non-token costs.

        • "0-200k"

        • "200k-1M"

      • cost_type: "tokens" or "web_search" or "code_execution" or "session_usage"

        Type of cost. null if not grouping by description.

        • "tokens"

        • "web_search"

        • "code_execution"

      • currency: string

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

      • description: string

        Description of the cost item. null if not grouping by description.

      • inference_geo: string

        Inference geo used matching requests' inference_geo parameter if set, otherwise the workspace's default_inference_geo. For models that do not support specifying inference_geo the value is "not_available". Always null if not grouping by inference geo.

      • model: string

        Model name used. null if not grouping by description or for non-token costs.

      • service_tier: "standard" or "batch"

        Service tier used. null if not grouping by description or for non-token costs.

        • "standard"

        • "batch"

      • token_type: "uncached_input_tokens" or "output_tokens" or "cache_read_input_tokens" or 2 more

        Type of token. null if not grouping by description or for non-token costs.

        • "uncached_input_tokens"

        • "output_tokens"

        • "cache_read_input_tokens"

        • "cache_creation.ephemeral_1h_input_tokens"

        • "cache_creation.ephemeral_5m_input_tokens"

      • workspace_id: string

        ID of the Workspace this cost is associated with. null if not grouping by workspace or for the default workspace.

    • starting_at: string

      Start of the time bucket (inclusive) in RFC 3339 format.

  • has_more: boolean

    Indicates if there are more results.

  • next_page: string

    Token to provide in as page in the subsequent request to retrieve the next page of data.
