Cloud Pricing API

The Cloud Pricing API is a GraphQL-based API that includes all public prices from AWS, Azure and Google; it contains over 3 million prices! The prices are automatically updated via a weekly job. This API is used by the Infracost CLI, thus you do not need to interact with it directly, however, you can also use it independently.

GraphQL is a natural fit for cloud pricing as it can model the JSON structure used by cloud vendors. This enables you to query nested JSON structures using vendor-specific parameters, and request only the attributes you need to be returned in the response. For example, you can find all prices that match AWS EC2 m3.large instance in us-east-1 (over 400 prices), then explore the 30+ attributes that AWS return to describe instances (e.g. clockSpeed or networkPerformance).

Concepts

The API has two main types: Products and Prices. Each product can have many Prices. This simple high-level schema provides flexibility to model the exact values that the cloud vendor APIs return at the same time as having useful top-level product filters. The values returned by the API are the same ones that the cloud vendors return in their APIs.

The main properties of Products are:

Name	AWS examples	Microsoft Azure examples	Google Cloud Platform examples
vendorName	aws	azure	gcp
service	AmazonEC2, AWSLambda, awskms	Virtual Machines, Functions, Azure DNS	Compute Engine, Cloud Functions, Cloud DNS
productFamily	Dedicated Host, Provisioned Throughput, Elastic Graphics	Compute, Storage, Databases	Compute Instance, License, Network
region	us-east-1, cn-north-1, us-gov-east-1	eastus, uknorth, US Gov	us-east1, europe, australia-southeast1
attributes (array of key-value pairs)	usagetype: UGE1-Lambda-Edge-Request, clockSpeed: 2.5 GHz	productName: Premium Functions, meterName: vCPU Duration	machineType: n2-highmem-64, description: Static Ip Charge

The main properties of Prices are:

Name	Description	Example
USD	Price from the cloud vendor in the preferred ISO 4217 currency code (e.g. EUR, BRL or INR). For non-USD currencies, prices are converted from USD to the preferred currency at query time.	USD: 0.2810000000
unit	Unit for the price	unit: Hrs
description	Any additional description	description: Upfront Fee
startUsageAmount	Start usage amount for price tier, only applicable for tiered pricing	startUsageAmount: 0
endUsageAmount	End usage amount for price tier, only applicable for tiered pricing	endUsageAmount: 10000
purchaseOption	Purchase option varies between vendors	on_demand, reserved, spot, Consumption, preemptible
termPurchaseOption	Term of the purchase option	termPurchaseOption: All Upfront
termLength	Length of the purchase option	termLength: 1yr
termOfferingClass	Offering class or type of the term	termOfferingClass: standard

Usage

Infracost runs a hosted version of this API that you can use:

1. Register for an API key by downloading infracost and running infracost auth login.
2. Pass the above API key using the X-Api-Key: xxxx HTTP header when calling https://pricing.api.infracost.io/graphql. The following example fetches the latest price for an AWS EC2 m3.large instance in us-east-1.

Curl request

curl https://pricing.api.infracost.io/graphql \
  -X POST \
  -H 'X-Api-Key: YOUR_API_KEY_HERE' \
  -H 'Content-Type: application/json' \
  --data '
  {"query": "{ products(filter: {vendorName: \"aws\", service: \"AmazonEC2\", productFamily: \"Compute Instance\", region: \"us-east-1\", attributeFilters: [{key: \"instanceType\", value: \"m3.large\"}, {key: \"operatingSystem\", value: \"Linux\"}, {key: \"tenancy\", value: \"Shared\"}, {key: \"capacitystatus\", value: \"Used\"}, {key: \"preInstalledSw\", value: \"NA\"}]}) { prices(filter: {purchaseOption: \"on_demand\"}) { USD } } } "}
  '

GraphQL playground request

The GraphQL Playground can be used with something like the modheader browser extension so you can set the custom HTTP header X-Api-Key to your Infracost API key.

query {
  products(
    filter: {
      vendorName: "aws",
      service: "AmazonEC2",
      productFamily: "Compute Instance",
      region: "us-east-1",
      attributeFilters: [
        { key: "instanceType", value: "m3.large" }
        { key: "operatingSystem", value: "Linux" }
        { key: "tenancy", value: "Shared" }
        { key: "capacitystatus", value: "Used" }
        { key: "preInstalledSw", value: "NA" }
      ]
    },
  ) {
    prices(
      filter: {purchaseOption: "on_demand"}
    ){ USD }
  }
}

Response

{"data":{
  "products":[
    {
      "prices":[
        {
          "USD":"0.1330000000"
        }
      ]
    }
  ]
}}
