You may get all on-orbit object information in 1 API call or track them individually or even filter them based on a specific group (like launch year, country of origin etc.). All values in a standard response from the API can be used as individual parameters. Using the "&limit=" parameter with a drastically high value will let you get all available data via a single API call. Make new calls frequently to update the live data for a smooth tracking experience.

• Geography: Location information such as latitude, longitude, altitude and direction.
• Core satellite data: Core details of the satellite such as the NORAD code, country of origin, name, and size
• Launch details: Exact launch date, year, number and part.
• ECI (Earth-centered inertial) Coordinates: The coordinates (position) of the satellite that are defined as the distance from the origin along the three orthogonal (mutually perpendicular) axes.
• Geographical location: Altitude, latitude and longitude values of the satellite's current location
• Orbit and ascension values: Orbital apogee, perigee, inclination and period  as well as right ascension values of the satellite
• TLE (Two-line Element Set): The two-line standard designation of satellite data consisting of satellite number, launch date and the parameters of its orbit
