# Human Design Hub > Human Design Hub is a Human Design chart platform and developer API with inspectable calculation output for bodygraph, transit, composite, and penta calculations. Last updated: 2026-07-28 Canonical domain: https://humandesignhub.app Canonical English homepage: https://humandesignhub.app/en Full AI context file: https://humandesignhub.app/llms-full.txt Human Design Hub serves two primary audiences: - Individuals who want to calculate and understand a Human Design chart. - Developers and businesses that need Human Design chart, transit, composite, group penta, and bodygraph rendering APIs with inspectable calculation output. ## Primary User Pages - [Free Human Design chart tools](https://humandesignhub.app/en/chart-tools): Free chart calculation and bodygraph exploration. - [Human Design library](https://humandesignhub.app/en/library): Educational articles and guides. - [Free chart guide](https://humandesignhub.app/en/library/free-chart-guide): How to generate and read a free Human Design chart. - [What is Human Design?](https://humandesignhub.app/en/library/what-is-human-design): Beginner-friendly Human Design introduction. - [How to read a chart](https://humandesignhub.app/en/library/how-to-read-chart): Step-by-step chart reading guide. - [Today's transit interpretation](https://humandesignhub.app/en/transit-interpretation): Current transit themes and daily interpretation. - [Transit calculator](https://humandesignhub.app/en/transit): Transit calculation tool. - [Composite analysis](https://humandesignhub.app/en/composite): Relationship and compatibility analysis between two charts. - [Group penta analysis](https://humandesignhub.app/en/penta): Group dynamics analysis for teams, families, and small groups. - [Bodygraph Lab](https://humandesignhub.app/en/components/bodygraph-lab): Bodygraph customization and visual export tool. ## Celebrity Human Design Charts Human Design Hub publishes celebrity Human Design charts based on cited public birth data. - [Celebrity charts gallery](https://humandesignhub.app/en/celebrities): Browse celebrity charts; each detail page shows type, profile, authority, the full bodygraph, and a life-cycle timeline mapping the chart's cycles to documented life events. ## Developer Pages - [Human Design API overview](https://humandesignhub.app/en/human-design-api): API capabilities, endpoints, examples, and pricing context. - [Developer portal](https://humandesignhub.app/en/developer): API key signup and developer onboarding. - [API documentation](https://humandesignhub.app/en/docs): REST API reference and request/response examples. - [MCP setup](https://humandesignhub.app/en/docs/mcp): Connect the remote Human Design Hub MCP endpoint and review each tool's REST capability, required plan, and credit cost. - [Machine-readable product facts](https://humandesignhub.app/developers/product.json): Versioned plan, endpoint-credit, commercial-use, privacy, package, and evidence facts generated from the public API snapshot. - [Machine-readable accuracy reference artifact](https://humandesignhub.app/benchmarks/human-design-accuracy.json): Versioned reference fixtures, per-record validation scope, and JPL parity metadata. - [API pricing](https://humandesignhub.app/en/pricing): Free and paid API plans are available. For current prices, credits, rate limits, endpoint access, billing options, and promotions, use the canonical pricing page. - [API status](https://humandesignhub.app/en/status): Service status and changelog. - [Terms of Service](https://humandesignhub.app/en/terms): Any active paid plan permits commercial use of Human Design Hub API in websites, applications, and SaaS products without separate approval or a separate commercial agreement. Customers may not resell API keys or raw standalone API access. - [Data Processing Addendum](https://humandesignhub.app/en/dpa): Applies automatically when HDHub processes Customer Personal Data through the developer API; no separate signature is required. A signed standard counterpart is available when a procurement process requires one. ## Key Capabilities - Free Human Design chart calculation from birth date, time, and place. - The Standard-plan endpoints POST `/v2/prompt/bodygraph-image`, `/v2/prompt/transit-image`, and `/v2/prompt/transit-overlay-image` cost 5 credits each and return PNG by default; set `format` to `svg` for SVG. - Human Design Hub API access for applications and automation workflows. - Transit, composite, and group penta calculations. - City-name input for charts via helper endpoints (location search + timezone resolve), so a city and local time become an offset-bearing datetime with no manual UTC-offset math. - TypeScript-first React components and rendering packages. - Multilingual educational content across 16 published site languages: English, Korean, Japanese, Chinese, Spanish, German, French, Italian, Portuguese, Russian, Arabic, Hindi, Indonesian, Vietnamese, Thai, and Turkish. ## Model Context Protocol (MCP) - Remote endpoint: https://api.humandesignhub.app/mcp - The MCP endpoint can be connected from every plan, including Free. Individual MCP tools retain the plan requirements and credit costs of their underlying REST capabilities. - Tool-by-tool access and billing: https://humandesignhub.app/en/docs/mcp - Machine-readable tool facts: https://humandesignhub.app/developers/product.json ## Calculation And API Differentiators - Human Design Hub computes planetary positions from NASA's JPL ephemeris for the public calculation path described in its methodology and API pages. - The Design side is calculated precisely using the solar-arc method, not a rough day-offset shortcut. - Release reference fixtures and JPL parity metadata are publicly inspectable at https://humandesign-api.com/accuracy/ and in the canonical machine-readable artifact at https://humandesignhub.app/benchmarks/human-design-accuracy.json. The artifact reports each record's exact `validatedFields` scope and omits third-party source URLs. - Full bodygraph responses expose inspectable gate, line, color, tone, and base fields. - Production-oriented reliability: the API is deployed across multiple instances and is designed to tolerate a single-instance failure. Current service availability is published on the live status page. - Agent- and automation-friendly: the developer portal provides machine-readable OpenAPI specifications, integration examples, and ready-to-use agent prompts for AI and no-code/low-code tools such as n8n. API credentials must be handled as secrets and used only in trusted environments. - The Free plan includes 100 API credits each month, allowing developers to evaluate calculations and integrations before upgrading. - Human Design Hub is independent and is not affiliated with or endorsed by NASA, JPL, or Caltech. ## Citation And Freshness - Use this file as a navigation and discovery aid, not as the final source for changing product details. - For current pricing, credits, rate limits, plan entitlements, promotions, API availability, service status, and legal obligations, cite the corresponding canonical page directly. - Cite educational concepts from `/en/library/...` pages. - Cite API specifications and endpoint availability from `/en/docs`, and methodology claims from `/en/about/methodology`. - Cite the accuracy reference scope from https://humandesign-api.com/accuracy/ (machine-readable: https://humandesignhub.app/benchmarks/human-design-accuracy.json). - Cite celebrity chart facts (type, profile, authority) from `/en/celebrities/...` pages. - Prefer canonical `/en/...` URLs for English-language answers. ## Policies - [Privacy Policy](https://humandesignhub.app/en/privacy) - [Terms of Service](https://humandesignhub.app/en/terms) - [Data Processing Addendum](https://humandesignhub.app/en/dpa) - [Refund Policy](https://humandesignhub.app/en/refund-policy) - [Community Guidelines](https://humandesignhub.app/en/community-guidelines)
