SoulTrace Personality Assessment

Take an adaptive personality assessment through the soultrace API. Answer 24 questions on a 1-7 Likert scale and receive your personality archetype based on a 5-color psychological model.

API Endpoint

POST https://soultrace.app/api/agent

No authentication required. Rate limited to 100 requests/hour per IP.

How It Works

The API is stateless. You pass all accumulated answers with every request, and the server replays the Bayesian inference to select the next optimal question.

Step 1: Start the test

Send an empty answers array to get the first question:

curl -X POST https://soultrace.app/api/agent \
  -H "Content-Type: application/json" \
  -d '{"answers": []}'
