Developer Platform · v1.4.0 Enhanced

The Astrocartography
Calculation Engine

Production-ready astrocartography REST API with advanced transit timing. Returns planetary line GeoJSON vectors, city compatibility scores, and transit-based timing intelligence with retrograde detection, lunar phases, and eclipse awareness.

As featured in National Geographic & Vogue
v1.4.0 New

Advanced Transit Features

Retrograde Detection

Mercury, Venus, Mars retrograde tracking with automatic potency adjustments and guidance messaging

Lunar Phases

8 moon phases with mode-specific meanings (New Moon travel starts, Full Moon avoid relocations)

Eclipse Detection

Solar & lunar eclipse proximity detection with intensity ratings for transformative moments
