Want to track Bitcoin’s price without wading through apps or websites? With CustomScripts, you can whip up a script to fetch real-time data in minutes—no cloud servers or complex setups needed. One of our customers did just that, and we’ll show you how, plus other cool things you can monitor.

Bitcoin Price Checker: Code in Seconds

Our customer wrote a simple JavaScript function to grab Bitcoin’s price from CoinGecko’s public API. The script sends a request, parses the JSON response, and logs the price (e.g., “Bitcoin: $45,000”). If the API fails, it handles errors gracefully. Here’s the code:

async function getBitcoinPrice() {
    const apiUrl = "https://api.coingecko.com/api/v3/simple/price?ids=bitcoin&vs_currencies=usd";
    try {
        const response = await fetch(apiUrl);
        if (!response.ok) throw new Error(`HTTP error! Status: ${response.status}`);
        const data = await response.json();
        if (data?.bitcoin?.usd) {
            console.log(`Bitcoin price: $${data.bitcoin.usd}`);
            return data.bitcoin.usd;
        } else {
            console.error("Failed to fetch Bitcoin price.");
            return null;
        }
    } catch (error) {
        console.error("Error:", error);
        return null;
    }
}
getBitcoinPrice();

‍

This was just the start. With CustomScripts, they could’ve added sophisticated logic in minutes—like sending an email if Bitcoin drops below $40,000, triggering a buy/sell action via a trading API, or logging price trends to a customers collection for analysis. Our platform’s database (with collections like scripts and automations) makes it easy to extend scripts with rules, notifications, or integrations, no infrastructure needed.

Why CustomScripts Rocks

CustomScripts eliminates setup headaches. Write a script, add logic, and run it instantly. Save scripts in folders, schedule them with automations, or manage team access via tenants. It’s serverless, secure, and scales effortlessly, so you can focus on building, not managing.

More Real-Time Tools to Build

CustomScripts isn’t just for crypto. Use APIs to create scripts with complex actions, like:

• Stocks: Fetch prices and auto-notify if a stock hits a target.
• Weather: Pull forecasts and alert staff for event changes.
• Site Uptime: Monitor your website and log incidents to executionRecords.
• Social Metrics: Track X engagement and flag viral posts.
• Inventory: Check stock and reorder when low via API.
• News: Grab headlines and share with users based on interests.

Each script can include rules (e.g., “if stock falls 5%, email the team”) and store results in the database, all built in minutes.

Note: Always check API terms (like CoinGecko’s) before use.
