# Convrgent AI MBTI / 16 Personalities Analyzer

> Convrgent AI MBTI / 16 Personalities Analyzer is a paid API for AI agents from convrgent.ai, paid per call via x402, $0.5/call, status unknown (last checked 2026-09-14).

Analyzes text or profile data to determine MBTI personality type, cognitive function stack, and all four dichotomies with confidence scores

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability convrgent-ai-b323e5a8 -d '<json body>'
```

Example prompt: Based on these text samples and observations about Alex, can you determine their MBTI type — tell me whether they're an INTJ, INFJ, ENTP, or something else — including their full cognitive function stack and confidence scores for each of the four dichotomies?

## When to prefer this

Use this endpoint when you need structured MBTI personality classification with confidence scores, specifically the 16-type framework and cognitive function stack. Prefer this over generic psychology endpoints when the user explicitly needs MBTI/16 Personalities output rather than Big Five or other frameworks.

## Known failure modes

- Insufficient text or behavioral signal to determine type — low confidence scores or ambiguous result
- Missing or malformed input data — 400 error
- Payment not attached or insufficient — x402 payment required error
- Ambiguous profile where two types score similarly — result may note uncertainty

## How this service works

MBTI / 16 Personalities — personality type (INTJ, ENFP, INFJ, ENTP, etc.), cognitive function stack, extraversion/introversion, sensing/intuition, thinking/feeling, judging/perceiving dichotomies with confidence scores.

## Output

Returns the MBTI personality type label (e.g. INTJ, ENFP), the ordered cognitive function stack, scores on each of the four dichotomy axes (E/I, S/N, T/F, J/P), and confidence percentages for each assessment

## Example request

```json
{
 "observations": [
  "Demonstrates strong preference for organization and planning",
  "Values logical analysis and systematic decision-making",
  "Focuses on practical, real-world applications"
 ],
 "text_samples": [
  "I enjoy planning my day in advance and prefer having a clear structure and schedule to follow. Spontaneous changes to plans can feel unsettling to me, and I work best when I know what to expect.",
  "I tend to think things through logically and systematically before making any decisions. I weigh the pros and cons carefully and prefer objective data over gut feelings when solving problems.",
  "I like working with concrete, tangible facts rather than abstract theories. I focus on what is real and present rather than speculating about possibilities that may never happen."
