Icelandic APIs — Free Iceland Data and Services API (No Key)

TL;DR

The Icelandic APIs project (apis.is) provides a collection of free REST APIs serving data about Iceland. Endpoints cover Icelandic weather forecasts, bus routes in Reykjavík (Strætó), airline schedules, government institution data, geography (municipalities, regions), and more. All APIs return JSON and require no authentication. A perfect resource for building Iceland-focused applications.

Quick start: http://apis.is/weather/climate?stations=1

Frequently Asked Questions

What endpoints are available?: Major endpoints include /weather, /bus/realtime, /company, /car, /airline, /pension, and /university/programs. Each provides Iceland-specific data from official sources.
Are the bus times real-time?: Yes — the Strætó bus endpoint provides real-time departure data from the Reykjavík bus system. Use the stop parameter with the stop name (e.g., Hlemmur, Lækjartorg, Mjódd).
What weather data is available?: Temperature, wind speed and direction, precipitation, humidity, and atmospheric pressure from Icelandic Meteorological Office stations across the country.
Can I look up individuals or just companies?: The company endpoint is for registered Icelandic companies (kennitala). It returns name, address, status, and registration date from the Icelandic Registry of Companies.
