Cloud Cost API

The Cloud Cost API provides multiple endpoints to obtain accurate cost information from your cloud service providers (CSPs), including data available from cloud billing reports (such as AWS' Cost and Usage Report (CUR)).

Cloud Cost querying API

GET http://<your-kubecost-address>/model/cloudCost

Samples full granularity of cloud costs from cloud billing report (ex. AWS' Cost and Usage Report)

Path Parameters

NameTypeDescription

window*

String

Duration of time over which to query. Accepts multiple different formats of time (see this Using the window parameter section for more info).

aggregate

String

Field by which to aggregate the results. Accepts: invoiceEntityID, accountID, provider, service, and label:<name>. Supports multi-aggregation using comma-separated lists. Example: aggregate=accountID,service

accumulate

boolean

When set to false, this endpoint returns daily time series data vs cumulative data. Default value is false.

offset

int

Refers to the number of line items you are offsetting. Pairs with limit. See the section on Using offset and limit parameters to parse payload results for more info.

limit

int

Refers to the number of line items per page. Pair with the offset parameter to filter your payload to specific pages of line items. You should also set accumulate=true to obtain a single list of line items, otherwise you will receive a group of line items per interval of time being sampled.

filter

string

Filter your results by any category which you can aggregate by, can support multiple filterable items in the same category in a comma-separated list. For example, to filter results by providers A and B, use filter=provider:providerA,providerB. See our Filter Parameters doc for a complete explanation of how to use filters and what categories are supported.

Schema overview

Cloud cost metrics

Cloud cost metric types values are based on and calculated following standard FinOps dimensions and metrics. The five types of cloud cost metrics provided by the Cloud Cost API are:

Cost MetricDescription

Amortized Net Cost

netCost with removed cash upfront fees and amortized (default)

Net Cost

Costs inclusive of discounts and credits. Will also include one-time and recurring charges.

List Cost

CSP pricing without any discounts

Invoiced Cost

Pricing based on usage during billing period

Amortized Cost

Effective/upfront cost across the billing period

See our Cloud Cost Metrics doc to learn more about these cost metric types and how they are calculated.

kubernetesPercent

Each cost metric also has a kubernetesPercent value. Unaggregated, this value will be 0 or 1. When you aggregate, kubernetesPercent is determined by multiplying the cost metric cost by its kubernetesPercent and aggregating that value as kubernetesCost for that cost metric. That kubernetesCost is then divided by the aggregated total costs to determine the new kubernetesPercent. Since this process results in unique values for each cost metric, this value is included as part of the cost metric.

Examples

Query for cloud net costs within the past two days, aggregated by accounts, filtered only for Amazon EC2 costs
