Retrieve ClickHouse Cloud organization usage cost, resource quotas, and the audit/activity log via the Cloud API

Documented steps

1. Usage cost: GET /v1/organizations/{organizationId}/usageCost with the REQUIRED query params from_date and to_date, both plain dates (YYYY-MM-DD). to_date cannot be more than 30 days after from_date, i.e. a maximum queried period of 31 days.
2. curl -s -u "$KEY_ID:$KEY_SECRET" 'https://api.clickhouse.cloud/v1/organizations/<organizationId>/usageCost?from_date=2026-07-01&to_date=2026-07-31'
3. Optionally add a repeatable `filter` query param to scope the report. Only resource-tag filtering is currently supported, e.g. filter=tag:Environment=Production.
4. The response is {grandTotalCHC, costs:[{dataWarehouseId, serviceId, date, entityType:'datawarehouse'|'service'|'clickpipe', entityId, entityName, metrics, totalCHC, locked}]}. Amounts are in ClickHouse Credits (CHC); `locked:false` means that day's figures can still change.
5. Quotas (beta): GET /v1/organizations/{organizationId}/quotas returns OrganizationQuota objects with quotaCode values 'services-per-organization', 'postgres-services-per-organization', or 'replicas-per-warehouse', plus name, description, scope ('organization'|'warehouse'), value, optional usage, and adjustable.
6. Fetch one quota with GET /v1/organizations/{organizationId}/quotas/{quotaCode}. curl -s -u "$KEY_ID:$KEY_SECRET" https://api.clickhouse.cloud/v1/organizations/<organizationId>/quotas/services-per-organization
7. Audit trail: GET /v1/organizations/{organizationId}/activities accepts OPTIONAL from_date and to_date. Omitting them returns the full history.
8. Each Activity is {id, createdAt, type (e.g. key_create, organization_member_update_roles, service_create, user_login), actorType:'user'|'support'|'system'|'api', actorId, actorDetails, actorIpAddress}. Fetch one with GET .../activities/{activityId}.
9. curl -s -u "$KEY_ID:$KEY_SECRET" 'https://api.clickhouse.cloud/v1/organizations/<organizationId>/activities?from_date=2026-07-01&to_date=2026-08-01'
