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
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.
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
POSThttps://convrgent.ai/api/kyh/mbtiUse 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.

"interpretation": "This individual presents as an ESTJ — the \"Executive\" — part of the Sentinels group. Organized, decisive leaders who value order, responsibility, and getting things done right. They create structure and hold people accountable, ensuring that traditions and standards are maintained.\n\nTheir preferences break down as: Extraversion (19% strength), Sensing (29%), Thinking (22%), and Judging (16%). Their cognitive function stack is led by Te (Extraverted Thinking) as the dominant function, supported by Si (Introverted Sensing) as the auxiliary. Under stress, their inferior function Fi (Introverted Feeling) may emerge in uncharacteristic ways.\n\nKey strengths include excellent organizer and administrator, decisive and action-oriented, reliable and committed. In communication, they tend to be direct, clear, and authoritative. states expectations plainly. values efficiency in communication. may come across as blunt or demanding. When making decisions, they are practical and efficient. relies on facts, data, and proven methods. decides quickly and expects action. values order and accountability.\n\nAreas for growth include listening to alternative perspectives and showing patience with different working styles and being more flexible with rules and procedures. An agent working with this person should be organized, factual, and action-oriented. present clear plans with timelines. respect their authority and position. be efficient — don't waste their time. follow through on commitments.",
