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": []}' Response: { "status" : "in_progress" , "question" : { "id" : 42 , "text" : "I find deep satisfaction in mastering complex systems." } , "currentDistribution" : { "white" : 0.2 , "blue" : 0.2 , "black" : 0.2 , "red" : 0.2 , "green" : 0.2 } , "entropy" : 2.322 , "progress" : { "answered" : 0 , "total" : 24 } } Step 2: Answer questions The user answers each question on a scale of 1-7: 1 = Strongly Disagree 4 = Neutral 7 = Strongly Agree Append the answer and send all answers so far: curl -X POST https://soultrace.app/api/agent \ -H "Content-Type: application/json" \ -d '{"answers": [{"questionId": 42, "score": 6}]}' Keep accumulating answers. Each response gives the next question. Step 3: Get results After 24 answers, the response automatically returns the final result: { "status" : "complete" , "resultId" : "abc-123-def" , "resultUrl" : "https://soultrace.app/en/results/abc-123-def" , "distribution" : { "white" : 0.15 , "blue" : 0.35 , "black" : 0.25 , "red" : 0.10 , "green" : 0.15 } , "entropy" : 1.89 , "archetype" : { "key" : "blue-black" , "name" : "Strategist" , "alignmentScore" : 87.3 , "coreDynamic" : "..." , "strengths" : [ "..." ] , "weaknesses" : [ "..." ] } , "topMatches" : [ { "key" : "blue-black" , "name" : "Strategist" , "alignmentScore" : 87.3 } , { "key" : "blue" , "name" : "Rationalist" , "alignmentScore" : 82.1 } , { "key" : "black-blue" , "name" : "Operator" , "alignmentScore" : 78.5 } ] , "shadowColors" : [ { "color" : "red" , "score" : 0.10 } , { "color" : "green" , "score" : 0.15 } ] , "progress" : { "answered" : 24 , "total" : 24 } } Agent Interaction Protocol When a user asks to take the personality test: Start by calling the API with {"answers": []} . Present each question to the user clearly. Tell them to answer 1-7 (1=Strongly Disagree, 4=Neutral, 7=Strongly Agree). Collect the user's numeric answer (1-7). If they give a non-numeric or descriptive answer, map it to the scale: "strongly disagree" / "not at all" → 1 "disagree" / "not really" → 2 "slightly disagree" → 3 "neutral" / "maybe" / "sometimes" → 4 "slightly agree" → 5 "agree" / "yes" → 6 "strongly agree" / "absolutely" → 7 Accumulate answers and send ALL previous answers plus the new one each time. After all 24 questions , present the results with: Their archetype name and alignment score Their color distribution (show as percentages) Their top 3 archetype matches The link to their full results page Never skip questions or auto-answer on behalf of the user.
