Human Design Transit API — Real-Time Planetary Transit Data

What Are Human Design Transits?

In Human Design, transits represent the current positions of celestial bodies mapped onto the bodygraph. Just as planets move through the sky, they activate different Gates and Channels in the global bodygraph — creating a “cosmic weather” that influences everyone.

When you overlay the current transit onto a person’s birth chart, you get personalized insights about what energies are active for them right now.

Transit API Endpoints

Basic Transit (Basic Plan)

POST /v1/transit

Returns the current planetary positions mapped to Human Design Gates. Perfect for daily transit reports.

curl -X POST https://api.humandesignhub.app/v1/transit \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"date": "2026-03-20T12:00:00Z"}'

Transit Overlay (Standard Plan)

POST /v1/transit-overlay

Combines a person’s birth chart with current transits to show which channels are activated, which centers become defined, and what themes are present.

const overlay = await fetch('https://api.humandesignhub.app/v1/transit-overlay', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer YOUR_API_KEY',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({
    birth_date: '1990-01-15',
    birth_time: '14:30',
    birth_place: 'Seoul, South Korea',
    transit_date: '2026-03-20T12:00:00Z',
  }),
});

Transit Window (Enterprise Plan)

POST /v1/transit-window

Calculate transits over a date range (up to 90 days). Returns daily transit data for building timeline views, calendars, and trend analysis.

Transit Overlay Window (Enterprise Plan)

POST /v1/transit-overlay-window

Personalized transit overlay for a date range — the most comprehensive transit endpoint.

Use Cases

• Daily transit reports: Show users what energies are active today
• Personalized transit alerts: Notify users when significant transits activate their chart
• Transit calendars: Build monthly/weekly transit views
• Compatibility timing: Find optimal dates for collaboration based on transit patterns
