  Add Cloud Cost Management tag endpoints

  May 13, 2026, 8:45 PM

  Added three new endpoints and supporting schemas for Cloud Cost Management tags: GET /api/v2/cost/tag_keys to list tag keys, GET /api/v2/cost/tag_keys/{tag_key} to get details for a specific tag key, and GET /api/v2/cost/tags to list tags. Also added an optional window[seconds] query parameter to the existing GET /api/v2/metrics/{metric_name}/volumes endpoint and updated its documentation to clarify it returns hourly average volumes.

  Add regression tracking to Issue schema

  May 13, 2026, 6:00 PM

  Added optional regression field to the Issue schema that references a new IssueRegression object containing regression metadata (regressed_at, regressed_at_version, resolved_at). This is a purely additive change that allows clients to track when previously resolved issues have reopened without breaking existing integrations.

  Add Cloud Cost Management anomalies APIs

  May 13, 2026, 5:30 PM

  Added two new endpoints for Cloud Cost Management anomalies: GET /api/v2/cost/anomalies to list detected cloud cost anomalies and GET /api/v2/cost/anomalies/{anomaly_id} to retrieve a specific anomaly. Also added supporting schemas (CostAnomaly, CostAnomaliesResponse, CostAnomalyResponse, and related types) and a new AnomalyID path parameter type. Both endpoints are marked as unstable/preview but represent purely additive functionality.

  Add API key validation endpoints

  May 12, 2026, 9:00 PM

  Two new endpoints were added for validating API credentials: GET /api/v2/validate validates an API key and returns the organization UUID, key ID, and scopes (in preview); GET /api/v2/validate_keys validates both API and application keys and returns a simple status. This is purely additive functionality that does not affect existing integrations.

  May 12, 2026, 8:00 PM

  Added two new POST endpoints POST /api/v2/statuspages/{page_id}/degradations/backfill and POST /api/v2/statuspages/{page_id}/maintenances/backfill to create backfilled incidents with predefined update timelines. This also introduces new request/response schema types (CreateBackfilledDegradationRequest, CreateBackfilledMaintenanceRequest) and supporting schemas for update entries, plus an optional updates field to existing degradation creation attributes.

  May 12, 2026, 5:45 PM

  Introduces new schema types (CostTagDescription, CostTagDescriptionAttributes, CostTagDescriptionSource, CostTagDescriptionType, CostTagDescriptionsResponse) and a new endpoint GET /api/v2/cost/tag_descriptions for listing Cloud Cost Management tag key descriptions. This is a purely additive change that does not affect existing functionality.
