FAQ
Frequently Asked Questions
What is the Human Design API? +
The Human Design API is a REST API that calculates Human Design bodygraph charts from birth data. It uses the Swiss Ephemeris engine for astronomical precision and returns chart components including Type, Strategy, Authority, Profile, Centers, Gates, and Channels.
How do I calculate a Human Design chart programmatically? +
Send a POST request to /v1/simple-bodygraph with birth_date, birth_time, and birth_place in the JSON body. The API returns the complete chart calculation including Type, Strategy, and Authority. Get your free API key at humandesignhub.app/developer.
Is there a free Human Design API? +
Yes. The Human Design API offers a free tier with 100 API credits per month and 5 requests per minute. No credit card required. The free tier includes the Simple Bodygraph endpoint for basic chart calculations.
What is a bodygraph and how does the API generate one? +
A bodygraph is the visual representation of a Human Design chart, showing 9 Centers, 64 Gates, and 36 Channels. The API calculates planetary positions at birth using Swiss Ephemeris, maps them to the I Ching hexagram system, and returns structured data you can use to render bodygraph visualizations.
Can I build a Human Design calculator with this API? +
Absolutely. The API handles all astronomical calculations — you provide birth data (date, time, place) and receive a complete chart. Use the free tier for prototyping, then upgrade for full bodygraph data, composite charts, and interactive visualization components.
What programming languages work with the Human Design API? +
Any language that can make HTTP requests works with the API. We provide examples in cURL, JavaScript, and Python. The API returns JSON, making it easy to integrate with React, Vue, Angular, Node.js, Django, Flask, or any other framework.
