As cloud computing becomes increasingly integral to data analysis, many developers and analysts are turning to lightweight, secure, and scalable environments. Azure Linux, Microsoft’s custom Linux distribution built specifically for Azure, offers a streamlined and efficient OS designed for performance and reliability in the cloud. Whether you’re building microservices or handling data workflows, Azure Linux provides a stable base, including support for containers, DevOps tools, and CLI-first workflows.

In this article, we’ll demonstrate how to fetch financial market and macroeconomic data directly into your Azure Linux virtual machine using the command line and an open-source REST API for stock and economic data.

Getting Started with Azure Linux

Before diving into data collection, ensure you have:

• An Azure account with a deployed Azure Linux VM (e.g., using Azure CLI or Azure Portal).


• curl and jq installed on your VM for API requests and JSON parsing.


• An API key for the Alpha Vantage stock API, which you can obtain for free at https://www.alphavantage.co/support/#api-key. Alternatively, you can choose other popular open-source fintech libraries such as Yahoo-Finance or IEX Cloud, although the latter has been deprecated and is available through (unofficial) community support.

You can install jq if it’s not already available:

sudo apt update && sudo apt install -y jq

Fetching Stock Market Data (e.g., Apple Inc.)

Alpha Vantage offers real-time and historical stock data. For example, to get daily adjusted time series data for AAPL (Apple Inc.), use:

API_KEY=your_alpha_vantage_key

SYMBOL=AAPL

curl -s “https://www.alphavantage.co/query?function=TIME_SERIES_DAILY_ADJUSTED&symbol=$SYMBOL&apikey=$API_KEY”

| jq ‘.[“Time Series (Daily)”] | to_entries[] | {date: .key, close: .value[“4. close”]}’

| head -n 10

This returns the latest several trading days’ worth of close prices for AAPL.

Fetching U.S. GDP Data

To fetch macroeconomic data such as quarterly U.S. GDP data:

curl -s “https://www.alphavantage.co/query?function=REAL_GDP&interval=quarterly&apikey=$API_KEY”

| jq ‘.data[] | {date: .date, value: .value}’

| head -n 10

This command lists recent GDP values (in billions of dollars) for each quarter.

Fetching the Federal Funds Rate

The Federal Funds Rate is a key interest rate affecting monetary policies. Here’s how to access it:

curl -s “https://www.alphavantage.co/query?function=FEDERAL_FUNDS_RATE&interval=monthly&apikey=$API_KEY”

| jq ‘.data[] | {date: .date, rate: .value}’

| head -n 10

You’ll receive a simple date and rate list showing the monthly federal funds rate data.

Bonus: Automation Tips

You can schedule these data retrievals using cron for daily, weekly, or monthly jobs:

crontab -e

Add an entry like the following to fetch AAPL prices every weekday at 5 PM UTC:

0 17 * * 1-5 /home/azureuser/fetch_aapl.sh >> /home/azureuser/aapl_data.log 2>&1

Where fetch_aapl.sh is a shell script wrapping the curl command shown earlier.

Conclusion

With just a few CLI tools and an API key, you can turn your Azure Linux VM into a powerful financial data node. Whether you’re developing financial models, building dashboards, or triggering economic alerts, Azure Linux makes it simple and efficient to work with critical market and macroeconomic data.
