THD API Docs

Getting started

Make your first THD API call in under 5 minutes.

Prerequisites

  • An API key from Studio
  • Node.js 18+ or Python 3.10+

Authenticate

All requests require a Bearer token. Generate a key at /keys.

Authorization: Bearer $THD_API_KEY

First API call — bodygraph

Use one of the following to generate a Human Design bodygraph:

curl -X POST "https://api.totalhumandesign.com/pi/v1/chart/bodygraph" \
  -H "Authorization: Bearer $THD_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name":"Jane Doe","birthDate":"1990-06-15","birthTime":"14:30","birthPlace":"New York, NY"}'
const response = await fetch("https://api.totalhumandesign.com/pi/v1/chart/bodygraph", {
  method: "POST",
  headers: {
    "Authorization": `Bearer ${process.env.THD_API_KEY}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    name: "Jane Doe",
    birthDate: "1990-06-15",
    birthTime: "14:30",
    birthPlace: "New York, NY",
  }),
})

const data = await response.json()
console.log(data)
