Overview

The Icelandic APIs project (apis.is) provides a collection of free, open APIs exposing various Icelandic public data including flights, currency rates, and public transportation. No API key is required, making it extremely easy to start using. It is a great free resource for developers interested in Icelandic data or building travel apps for Iceland.

💡

Beginner Tip

No registration or API key is needed — simply call the endpoints directly. Start with the /flight endpoint to explore Keflavik airport arrivals and departures, or /currency for live ISK exchange rates.

Common Errors & Troubleshooting

Connection timeout or no response The apis.is service may have intermittent downtime as it is community-maintained
✓ Add retry logic with a short delay in your code. If the service is down, check the GitHub repository at https://github.com/apis-is/apis for status updates.
Empty results array No flights or data available for the requested time window
✓ Try the request without time filters first to verify the endpoint is working, then narrow down with date parameters.
CORS error in browser The HTTP (non-HTTPS) endpoints may be blocked by modern browsers
✓ Make the request from a server-side script (Node.js, Python) instead of directly from a browser, or use the HTTPS version of the URL.
