Azure Pricing

Azure Pricing Skill

Use this skill to retrieve real-time Azure retail pricing data from the public Azure Retail Prices API. No authentication is required.

API Endpoint

GET https://prices.azure.com/api/retail/prices?api-version=2023-01-01-preview

Append $filter as a query parameter using OData filter syntax. Always use api-version=2023-01-01-preview to ensure savings plan data is included.

Step-by-step Instructions

If anything is unclear about the user's request, ask clarifying questions to identify the correct filter fields and values before calling the API.

1. Identify filter fields from the user's request (service name, region, SKU, price type).
2. Resolve the region: the API requires armRegionName values in lowercase with no spaces (e.g. "East US" → eastus, "West Europe" → westeurope, "Southeast Asia" → southeastasia). Derive this from the user's input.
3. Build the filter string using the fields below and fetch the URL.
4. Parse the Items array from the JSON response. Each item contains price and metadata.
5. Follow pagination via NextPageLink if you need more than the first 1000 results (rarely needed).
6. ALWAYS pass unit prices to the cost_estimator tool to produce monthly/annual estimates.

Filterable Fields

Use eq for equality, and to combine, and contains(field, 'value') for partial matches.

Example Filter Strings

# All consumption prices for Azure Functions in East US
serviceName eq 'Azure Functions' and armRegionName eq 'eastus' and priceType eq 'Consumption'

# D4s v5 VMs in West Europe (consumption only)
armSkuName eq 'Standard_D4s_v5' and armRegionName eq 'westeurope' and priceType eq 'Consumption'

# All storage prices in a region
serviceFamily eq 'Storage' and armRegionName eq 'eastus'

# Spot pricing for a specific SKU
armSkuName eq 'Standard_D4s_v5' and contains(meterName, 'Spot') and armRegionName eq 'eastus'

# 1-year reservation pricing
serviceName eq 'Virtual Machines' and priceType eq 'Reservation' and armRegionName eq 'eastus'

Full Example Fetch URL

https://prices.azure.com/api/retail/prices?api-version=2023-01-01-preview&$filter=serviceName eq 'Azure Functions' and armRegionName eq 'eastus' and priceType eq 'Consumption'

URL-encode spaces as %20 and quotes as %27 when constructing the URL.

Key Response Fields

{
  "Items": [
    {
      "retailPrice": 0.000016,
      "unitPrice": 0.000016,
      "currencyCode": "USD",
      "unitOfMeasure": "1 Execution",
      "serviceName": "Azure Functions",
      "skuName": "Consumption Tier",
      "armRegionName": "eastus",
      "meterName": "Standard Executions",
      "productName": "Azure Functions",
      "priceType": "Consumption",
      "isPrimaryMeterRegion": true
    }
  ],
  "NextPageLink": null,
  "Count": 1
}

Only use items where isPrimaryMeterRegion is true unless the user specifically asks for non-primary meters.

Supported serviceFamily Values

Analytics, Compute, Containers, Data, Databases, Developer Tools, Integration, Internet of Things, Management and Governance, Networking, Security, Storage, Web, AI + Machine Learning

Tips

• serviceName values are case-sensitive. When unsure, filter by serviceFamily first to discover valid serviceName values in the results.
• If results are empty, try broadening the filter (e.g., remove priceType or region constraints first).
• Prices are always in USD unless currencyCode is specified in the request.
• For savings plan prices, look for the savingsPlan array on each item (only in 2023-01-01-preview).
