Overview

List Cloud Cost Management tag key metadata, including row counts, cost covered, cardinality, and a sample of top tag values per cloud account. Use filter[daily]=true to return daily rows instead of the default monthly roll-up. This endpoint requires the cloud_cost_management_read permission.

OAuth apps require the cloud_cost_management_read authorization scope to access this endpoint.

Arguments

Query Strings

Name

Type

Description

filter[month] [required]

string

The month to scope the query to, in YYYY-MM format.

filter[provider]

string

Filter results to a specific provider. Common cloud values are aws, azure, gcp, Oracle (OCI), and custom. SaaS billing integrations (for example, Snowflake, MongoDB, Databricks) are also accepted using their display-name string. Values are case-sensitive.

filter[metric]

string

Filter results to a specific Cloud Cost Management metric (for example, aws.cost.net.amortized). When omitted, every available metric for the requested period is returned.

filter[tag_key]

string

Restrict results to a single tag key.

filter[daily]

enum

When true, return one row per day with the day in the date attribute. Defaults to the monthly roll-up when omitted.
Allowed enum values: true, false

Response

OK

List of Cloud Cost Management tag key metadata entries for the requested period.

cardinality_by_account [required]

object

Number of unique tag values observed for this tag key, keyed by cloud account ID.

<any-key>

int64

Number of unique tag values observed in the account.

cost_covered [required]

double

Total cost (in the report currency) of cost line items that carry this tag key for the requested period.

date

string

The day this row corresponds to, in YYYY-MM-DD format. Present only when filter[daily]=true; omitted for the monthly roll-up returned by default.

metric [required]

string

The Cloud Cost Management metric this row aggregates, for example aws.cost.net.amortized.

row_count [required]

int64

Number of cost rows that carry this tag key over the requested period.

tag_sources [required]

[string]

Origins where this tag key was observed (for example, aws-user-defined).

top_values_by_account [required]

object

A sample of the most frequent tag values observed for this tag key, keyed by cloud account ID.

<any-key>

[string]

A sample of the most frequent tag values observed in the account.

id [required]

string

A composite identifier of the form tag_key:metric for monthly roll-ups, or tag_key:metric:YYYY-MM-DD when filter[daily]=true.

type [required]

enum

Type of the Cloud Cost Management tag key metadata resource. Allowed enum values: cost_tag_key_metadata

default: cost_tag_key_metadata
