Quick start

# 1) Resolve a birth city to coordinates
curl "https://hdmatrix.pro/api/v1/geocode?q=Kyiv, Ukraine"
# -> { "name": "Kyiv, Ukraine", "lat": 50.45, "lon": 30.52 }

# 2) Calculate a full Human Design chart (no API key)
curl -X POST "https://hdmatrix.pro/api/v1/calculate" \
  -H "Content-Type: application/json" \
  -d '{
    "birth_date": "15.05.1990",
    "birth_time": "10:30",
    "birth_place": "Kyiv, Ukraine",
    "lat": 50.45, "lng": 30.52
  }'

FAQ

Is the HD Matrix API free?

Yes. The public v1 API and the MCP server are free and require no API key. Usage is rate-limited per IP to keep the service healthy.

How do I use the API from an AI agent or custom GPT?

Import the OpenAPI 3.1 schema at https://hdmatrix.pro/openapi.json as a tool/Action, or connect the MCP server at https://hdmatrix.pro/mcp. No authentication is needed.

What is the MCP server?

A Model Context Protocol server (JSON-RPC 2.0 over Streamable-HTTP, protocol version 2025-06-18) at https://hdmatrix.pro/mcp. It exposes five tools and works with Claude Desktop, Cursor, Windsurf, Cline and Continue.

Do I need coordinates to calculate a chart?

You can pass latitude/longitude directly, or pass a birth place string — call /api/v1/geocode first to resolve a city to coordinates, then /api/v1/calculate.

What error codes does the API return?

Errors use structured JSON with a code field, e.g. RATE_LIMIT_EXCEEDED, MISSING_FIELD, GEOCODE_FAILED, plus standard HTTP status codes. Rate-limit responses include X-RateLimit-Limit and X-RateLimit-Remaining headers.
