Use `filter[cloud]` to scope the result to a single cloud provider; when omitted, both cross-cloud defaults and cloud-specific descriptions are returned. This endpoint requires the `cloud_cost_management_read` permission. OAuth apps require the `cloud_cost_management_read` authorization [scope](https://docs.datadoghq.com/api/latest/scopes.md#cloud-cost-management) to access this endpoint. ### Arguments #### Query Strings | Name | Type | Description | | ------------- | ------ | --------------------------------------------------------------------------------------------------------------------- | | filter[cloud] | string | Filter descriptions to a specific cloud provider (for example, `aws`). Omit to return descriptions across all clouds. | ### Response {% tab title="200" %} OK {% tab title="Model" %} List of Cloud Cost Management tag key descriptions for the organization, optionally filtered to a single cloud provider. | Parent field | Field | Type | Description | | ------------ | ----------------------------- | -------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | | data [*required*] | [object] | List of tag key descriptions. | | data | attributes [*required*] | object | Human-readable description and metadata attached to a Cloud Cost Management tag key, optionally scoped to a single cloud provider. | | attributes | cloud [*required*] | string | Cloud provider this description applies to (for example, `aws`). Empty when the description is the cross-cloud default for the tag key. | | attributes | created_at [*required*] | string | Timestamp when the description was created, in RFC 3339 format. | | attributes | description [*required*] | string | The human-readable description for the tag key. | | attributes | source [*required*] | enum | Origin of the description. `human` indicates the description was written by a user, `ai_generated` was produced by AI, and `datadog` is a default supplied by Datadog. Allowed enum values: `human,ai_generated,datadog` | | attributes | tag_key [*required*] | string | The tag key this description applies to. | | attributes | updated_at [*required*] | string | Timestamp when the description was last updated, in RFC 3339 format. | | data | id [*required*] | string | Stable identifier of the tag description. Equals the tag key when the description is the cross-cloud default; encodes both the cloud and the tag key when the description is cloud-specific. | | data | type [*required*] | enum | Type of the Cloud Cost Management tag description resource.
