Embed SDK

One script tag, 16 calculators

The embed SDK gives you both API access and a drop-in widget. Same calculation engine. Different integration options.

<!-- Step 1: Add the SDK -->
&lt;script src="https://salarylabs.site/js/salarylab-embed.js"&gt;</script&gt;

<!-- Step 2: Initialize with your API key -->
&lt;script&gt;
  SalaryLab.init(
    apiKey: 'your_api_key_here',
    theme: 'light'  // or 'dark'
  );
&lt;/script&gt;

<!-- Step 3: Mount a calculator -->
&lt;div id="salary-calc"&gt;</div&gt;
&lt;script&gt;
  SalaryLab.mount(
    el: '#salary-calc',
    tool: 'take-home-pay',
    defaults: (
      gross: 85000,
      state: 'CA'
    )
  );
&lt;/script&gt;
