Human Design Hub

About Human Design Hub

Human Design Hub provides a REST API for calculating Human Design charts and related data from a birth datetime. Endpoints cover core chart generation (simple bodygraph, full bodygraph with gate/line/color/tone/base output), circuits, not-self deck and gate diagnostics, transits and transit overlays, cycle analysis, dreamrave sleep charts, composite charts, and penta charts, along with image-rendering versions of several endpoints. Helper endpoints resolve city names to coordinates and IANA timezones and convert local date/time input into offset-bearing ISO datetimes for use in chart requests.

Access requires an API key sent via the X-API-KEY header. Usage is metered by credits, with per-endpoint costs ranging from 0.1 credits for location search and timezone resolution up to 8 credits for transit-overlay window calculations; some endpoints (e.g. full bodygraph) require a Standard plan or higher. Plans include Free (100 credits/month, 5 requests/min), Basic ($9.99/mo, 10,000 credits, 100 req/min), Standard ($29.99/mo, 50,000 credits, 500 req/min), Pro ($49.99/mo, 120,000 credits, 1,000 req/min), and a custom Enterprise tier with unlimited credits and 2,000 req/min.

The product is aimed at developers building applications that incorporate Human Design chart calculations, such as chart-reading tools, astrology-adjacent apps, or integrations needing programmatic access to bodygraph, transit, and cycle data.

Key features

• Calculates Human Design bodygraphs (gates, lines, colors, tones, bases) from birth datetime
• Resolves city names and local times to offset-bearing ISO datetimes via location search and timezone endpoints
• Generates circuits, not-self deck, and not-self gate diagnostics from birth activations
• Computes transit charts, transit overlays, and cycle-analysis life-cycle timings
• Produces bodygraph and transit chart images via dedicated image endpoints
• Credit-based REST API authenticated with an X-API-KEY header
