  "description_for_model": "Free Human Design API. Use calculateChart to compute a full Human Design (Rave) chart from birth data (year, month, day, hour, minute, place + latitude/longitude) — returns type, strategy, authority, profile, definition, incarnation cross, defined/undefined centers, channels, personality/design gates (each with its planet), and an aiSummary; invalid birth data returns HTTP 400 with details. Use getInterpretation for the meaning of any HD element (type, authority, profile, gate, gate_line, channel, center_defined, center_undefined, cross, cross_quantum, planet, gene_key, transit_gate, phs_*, and more). Use listInterpretations (GET /api/v1/interpret/list, optionally ?type=) to discover the exact valid keys for a type before calling getInterpretation, instead of guessing. The interpret endpoint canonicalizes common key variants (channel \"3-60\"=\"60/3\", authority case-insensitive, gate numeric or gate_N). Use getTransits for today's planetary activations from birth data. No API key required (free tier, rate-limited per IP).",
