Natal Horoscope

The Natal horoscope, also known as a birth horoscope, calculates a person's unique and personal astrological report based on birthdate, birthplace and birthtime. This is the most widely used horoscope.

Basic Flow

To generate a Natal Horoscope from the AstroAPI, the system (your implementation) makes a POST-request to the /api/natal endpoint with the necessary parameters. With correct parameters the AstroAPI will provide a full natal horoscope in JSON-format + the astrological wheel image url.


The AstroAPI can also calculate asteroids. The following asteroids are available:

  • Apollo (id: 11862)
  • Eros (id: 10433)
  • Pallas (id: 18)
  • Athene (id: 10881)

Add the ID to the planets array to calculate the asteroid.
