Render Your Visual Chart.
Turn Human Design Chart data into a stylable, edge-rendered SVG you drop straight into your app. Available on Developer plans and up.
Easy and fast
Drop a simple URL into your app, chart renders on the edge.
Style it your way
svgRenderUrl returns clean SVG, drop into an img tag or CSS background-image, style however you want.
Your own branding
Build a custom chart style in the template editor.
Whether you're hand-coding a custom engine or prompting your next big idea, we provide the raw power you need.
Prompt-to-Product in Minutes.
Our API is designed to be consumed by AI coding tools like n8n, Lovable, Bolt.new and LLM-based agents out of the box.
Describe It
Tell your AI assistant what you want to build using our API.
AI Builds It
Your AI tool integrates our API, writes the code, and renders the chart.
Ship It
Clean JSON responses, no SDK needed. Ship-ready from first prompt.
Use the Human Design API's /v2/visual-charts endpoint. Accept birthdate, time, and location inputs, then render the bodygraph as data and visuals: a profile card on one side, the returned svgRenderUrl in an <img> tag on the other.

See why developers choose our API to power their Human Design applications.
Great API to work with. Easy to install and integrates seamlessly with my n8n and Notion workflow. The support is fast and dedicated (and also in Dutch).
Using the Human Design API, I can access the data needed to help people connect with their ancestors through personalized archetypes. The API is both easy to use and highly reliable for the accuracy I require daily. The support is exceptional; Matthijs went above and beyond to help me troubleshoot, making me feel like I have a true partner rather than just a tool. I wouldn’t be able to help others heal through their ancestral stories without it.
Working with this API was a really smooth experience. It connected seamlessly into my custom REVEAL Human Design project, and one of the things I appreciated most was the flexibility to tailor the readings in a way that fit my brand voice and audience. It gave me a strong foundation to build something that felt both functional, personalized and authentic from me, created for my audience.
I use the Human Design API as a data engine to facilitate my studies of competition and friction on teams to enhance teamwork and performance.
The API for the Human Design was very easy to use. It enabled me to feed the human design data to an AI model that finds (hidden) patterns in someones design to give them better and more personalized insights.
The API was easy to use, and when we had a new feature request they made a live update in record time!

FAQ
Frequently Asked Questions
- Our calculations are based on the NASA JPL Ephemeris. Planetary positions, gate activations, and channel definitions are computed from first principles — no scraping, no third-party chart services.
- Every release is tested against a reference set of known charts with verified gate and channel activations. We compare our planetary degree calculations against the NASA JPL Ephemeris directly, ensuring that no rounding or conversion errors affect the final Human Design chart data.
- You get API access to accurate Human Design chart data per request. The Hobbyist plan returns basic data: energy types, profiles, gates, channels, and centers. Developer and higher plans return the full dataset: all basic data plus strategy & authority, incarnation cross, variables & cognition, all activations, definition, and signature & not-self theme. See the full JSON response spec in the documentation.
- The Hobbyist plan returns energy types, profiles, gates, channels, and centers via the
/v2/charts/simpleendpoint. Developer and Scale plans unlock the full dataset — strategy & authority, incarnation cross, variables & cognition, all activations, definition, signature & not-self theme, and more — across three endpoints:/v2/charts,/v2/charts/simple, and/v2/charts/coordinates. Browse the full field reference in the documentation. - The Human Design API is a RESTful API that returns JSON. You can call it from any programming language or platform that can make HTTP requests — including Node.js, Python, PHP, Ruby, and no-code tools like n8n, Make, and Zapier. Authentication is via API key passed in the request header. See the quickstart guide in the documentation.
- Each API call costs one credit. Plans include a monthly credit allowance: 5,000 on Hobbyist, 10,000 on Developer, and 50,000 on Scale. If you exceed your allowance, additional credits are billed at your plan's rollover rate (€1.00 - €2.00 per 1,000 credits depending on plan). Credits reset monthly. The Lifetime plan includes 50,000 credits per month.
- There is no free tier. The entry-level Hobbyist plan starts at €22.50/month and includes 5,000 monthly credits and basic chart data — enough to build and test a full integration. All plans include a 7-day refund policy. Compare all plans.
- This API is for developers who want to build Human Design apps. Using this API requires you to have some coding skills, know how to use a no/low-code platform, or have access to someone who can do either of these.
- No. Only the data is returned. The visual chart is not included. You can follow the tutorial to create your own visual chart from the data.
- Yes, you can upgrade at any time from your dashboard. Your new plan activates immediately and your API key keeps working without interruption. Credits reset to your new plan's monthly allowance on your next billing date.
- Yes! You can request a refund within 7 days of your purchase. Reach out by email. Please note that you will be charged 3.5% of the purchase value for the refund processing fee.

Built by a developer, for developers.
Hey there, I'm Matthijs, a full-stack developer with a background in aeronautical engineering and 10 years of experience building data-driven products. I built the Human Design API because I needed accurate, reliable chart data in my own projects and couldn't find anything worth using. So I built it myself. Every endpoint, every data point, every uptime decision: made by someone who actually uses it.
