// Fetch all featured tools from Utilko
const res = await fetch('https://utilko.com/api/tools');
const data = await res.json();

console.log(`Total tools: ${data.total_tools}`);

data.featured_tools.forEach(tool => {
  console.log(`${tool.name} — ${tool.url}`);
});

Python Fetch tools with requests

import requests

res = requests.get('https://utilko.com/api/tools')
data = res.json()

print(f"Total tools: {data['total_tools']}")

for tool in data['featured_tools']:
    print(f"{tool['name']} — {tool['url']}")

curl Quick test in your terminal

curl https://utilko.com/api/tools | jq '.'

# Pretty print just the tool names
curl -s https://utilko.com/api/tools | jq '[.featured_tools[].name]'

Embed Tools on Your Site

You can embed any Utilko tool directly into your website using our widget script. Just add one line of HTML:

<!-- Embed the JSON Formatter tool -->
<script src="https://utilko.com/widget.js" data-tool="json-formatter"></script>

<!-- Embed the Password Generator -->
<script src="https://utilko.com/widget.js" data-tool="password-generator"></script>

<!-- Custom size -->
<script
  src="https://utilko.com/widget.js"
  data-tool="word-counter"
  data-width="800"
  data-height="600"
></script>

The widget inserts an iframe automatically. Supported data-tool values match the tool slug in Utilko URLs (e.g. json-formatter, bmi-calculator, etc.)

No API Key Required

The Utilko API is completely free and public. No registration, no API key, no rate limits. Just fetch and use. If you build something with it, let us know — we'd love to feature it.
