Reports & Analytics

Track cloud costs, savings from automated scheduling, and monitor resource utilization across all your connected accounts.

Dashboard Summary

GET /reports/summary

Get an overall cost and savings summary for the current period.

{
  "data": {
    "totalCostUSD": 12450.50,
    "totalSavingsUSD": 3280.75,
    "resourceCount": 156,
    "period": "2025-01"
  }
}

Cost Flow (Sankey)

A configurable Sankey view of how cost flows across providers, accounts, regions, resource types, services, purchase types, and teams. The default flow is Provider -> Account -> ResourceType -> Team and can be reshaped to any ordered sequence of dimensions; the URL is shareable so a drilldown can be sent in chat.

Supported dimensions

provider
cloud_account_id
region
resource_type
service_name
purchase_type
team_id
resource_uid (drilldown only)

Overlays

Savings overlay — highlights links carrying idle, orphan, or right-sizing savings opportunities surfaced by Recommendations.
Unattributed overlay — surfaces cost flowing to resources missing team or tag attribution. Use this to find gaps in Smart Tags coverage.

GET /reports/costs/breakdown

Generic GROUP BY on cost_records. Reusable for the Sankey, treemaps, custom dashboards, anything future.

Query parameters:

dims — comma-separated dimension list, in order. Allowlisted to the dimensions above.
from / to — ISO 8601 date range.
filter[dim]=value — repeatable, scopes the breakdown.

    ],
    "totalUSD": 4200.50
  }
}

Export

The Sankey supports CSV and PNG export. CSV exports the underlying flow rows (source, target, dimension, value); PNG exports the rendered diagram with the same URL-encoded state.

Cost Anomaly Detection

ZopNight detects unusual cost spikes across five dimensions (org, cloud account, resource group, resource, team) using percentage deviation and z-score analysis, with 14-day root-cause attribution. See Cost Anomaly Detection for the full feature, including detection algorithm, notification cooldown, dedup, and the two-level drawer.

Cost Attribution (Showback)

Slice cost by team (derived from resource group ownership) or by tag (cloud tags, GCP labels, Azure tags, and accepted smart tags). Both dimensions are computed from the same daily billing rollup, so team and tag totals always reconcile to the provider total.

Scheduler Events

  ]
}

POST /events

Unit Economics

Unit economics correlate spend with business KPIs — cost per order, cost per active user, cost per build minute — so teams can compare cost movement against demand rather than treating spend as a raw line item. Define a metric in /unit-metrics (push, pull, or CSV ingestion), then send values for it and read the resulting series back through Reports.

POST /unit-metric-values/{id}

Push a batch of values for a unit metric. Returns the number of rows ingested. Use for low-volume push integrations and webhooks.

POST /unit-metric-values/{id}/csv

Upload a CSV of historical values. Accepts a single CSV file per request; rows are upserted by timestamp.

POST /unit-metric-values/{id}/test-pull

Run the configured pull integration once and return the rows it produced — without persisting anything. Used by the metric editor's 'Test connection' button.

DELETE /unit-metric-values/{id}

Drop every stored value for a metric. Useful when reseeding from a corrected source.

GET /reports/unit-economics

Time-series of cost-per-unit for a chosen metric, with optional filters (provider, team, tag). Used by the Unit Economics chart on the cost dashboard.
