If you have any feedback, contact [Datadog support](https://docs.datadoghq.com/help/). | Datadog site | API endpoint | | ----------------- | ---------------------------------------------------------------------- | | ap1.datadoghq.com | GET https://api.ap1.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | | ap2.datadoghq.com | GET https://api.ap2.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | | app.datadoghq.eu | GET https://api.datadoghq.eu/api/v2/cost/tag_metadata/tag_sources | | app.ddog-gov.com | GET https://api.ddog-gov.com/api/v2/cost/tag_metadata/tag_sources | | us2.ddog-gov.com | GET https://api.us2.ddog-gov.com/api/v2/cost/tag_metadata/tag_sources | | uk1.datadoghq.com | GET https://api.uk1.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | | app.datadoghq.com | GET https://api.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | | us3.datadoghq.com | GET https://api.us3.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | | us5.datadoghq.com | GET https://api.us5.datadoghq.com/api/v2/cost/tag_metadata/tag_sources | ### Overview List Cloud Cost Management tag keys observed for the requested period, along with the origin sources that produced them (for example, `aws-user-defined`, `custom`). 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[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 tag keys that have data for a specific Cloud Cost Management metric (for example, `aws.cost.net.amortized`). When omitted, all tag keys for the requested period are returned. | ### Response {% tab title="200" %} OK {% tab title="Model" %} List of Cloud Cost Management tag keys with their origin sources for the requested period. | Parent field | Field | Type | Description | | ------------ | ----------------------------- | -------- | ------------------------------------------------------------------------------------------------------ | | | data [*required*] | [object] | List of tag keys with their origin sources. | | data | attributes [*required*] | object | Attributes of a Cloud Cost Management tag source. | | attributes | tag_key [*required*] | string | The tag key name. | | attributes | tag_sources [*required*] | [string] | Origins where this tag key was observed (for example, `aws-user-defined`). | | data | id [*required*] | string | The tag key identifier.
