The ISS position API, drawn as an interface
Where the ISS at? returns the International Space Station’s position at this moment: latitude and longitude, altitude and velocity in kilometres, the footprint it can see, whether it is in daylight, and a Unix timestamp.
Imago leads with velocity and footprint, reads the timestamp as a clock time and the coordinates as degrees. Open it in Imago and turn on Watch to see which values change on every fetch.

Free, with or without a key
Imago is free and open source. Bring your own free Gemini or Groq key, or use none. With no key you get the page above, drawn by rules that know no particular API. A key gets you a designed layout. It stays in your browser and goes only to the provider you chose.
