No other API offers this
Group Penta is a Human Design framework for analyzing the emergent dynamics of small groups (3-5 people). The POST /v1/group/penta endpoint (Standard plan, 3.0 credits) is exclusive to the Human Design Hub API. No competitor — not humandesignapi.nl, not hdkit, not any open-source library — provides automated Group Penta calculation.
What Group Penta analyzes
When 3 to 5 people come together, their individual charts combine to create an emergent group field called the Penta. The API calculates:
- Defined Centers in the Penta — Which of the 9 Centers are consistently defined by the group’s combined energy. These are the group’s reliable strengths.
- Dominant Gates — Which Gates are activated by multiple members, creating strong group themes.
- Active Channels — Channels formed by the combination of different members’ Gates, representing the group’s functional capacities.
- Per-member contribution — What each person uniquely brings to the group field, helping identify roles and irreplaceable contributions.
Set verbose=true for detailed per-member breakdowns.

}'Use case scenarios
HR tech and team composition — Analyze prospective team configurations before forming project teams. Identify which combination of candidates creates the strongest Penta field.
Group coaching platforms — Provide coaches with a visual map of group dynamics. Show where the group has natural strengths and where external support may be needed.
Corporate training tools — Build workshop facilitation tools that reveal team dynamics in real-time during corporate training sessions.
Retreat and community planning — Help retreat organizers group participants into Penta-optimized small groups for breakout sessions.
Competitive advantage
This endpoint is a market differentiator. If your application involves group dynamics, team analysis, or any multi-person Human Design context, the Human Design Hub API is the only programmatic option. The alternative is manual calculation by a trained analyst, which typically costs $200-500 per group reading.
