Overview

Iconfinder (now served through the Freepik API) gives access to a massive library of icons and vector graphics you can search, filter by style, and download in various formats. Designers and developers use it to find consistent icons for UI projects without needing a subscription to individual icon packs. An API key is required.

💡

Beginner Tip

Get a Freepik API key at https://freepik.com/api to access the icons endpoint. Use the search endpoint with a keyword like "home" to browse available icons before downloading.

Common Errors & Troubleshooting

401 Unauthorized Missing or invalid Freepik API key in the request header
✓ Add the header "x-freepik-api-key: YOUR_API_KEY" to every request
Empty results array Search term too specific or the icon style filter excludes all results
✓ Broaden your search term or remove style filters; try a generic word like "arrow" to test the integration
CORS blocked in browser The API does not advertise CORS support for all origins
✓ Route API calls through your backend server to avoid browser CORS restrictions
