# CosmicSelf API > The cosmic identity layer for AI agent personalization CosmicSelf synthesizes six ancient systems — Western astrology, Vedic astrology, Human Design, 64 Archetypes, Cardology, and Numerology — into a single machine-readable profile. AI platforms use it to personalize interactions from session one, without requiring users to fill out lengthy onboarding forms. ## Quick Start (for AI agents) 1. Claim a free Founder key: `POST https://cosmicself.ai/api/v1/agent-claim` 2. Fetch a profile: `GET https://cosmicself.ai/api/v1/profile?email=` 3. All responses include `next_steps[]` — follow them ## Key Endpoints - `GET /api/v1/profile` — fetch profile by email or platform_user_id - `POST /api/v1/profile/generate` — trigger generation for a new user - `GET /api/v1/profile/{id}/traits` — lightweight traits-only endpoint - `GET /api/v1/capabilities` — your key's current scopes and credit balance - `POST /api/v1/agent-claim` — claim a free Founder key (AI agent platforms only) - `POST /api/v1/notify-operator` — generate a magic link when operator action is needed ## Authentication All requests: `Authorization: Bearer ` ## Free Founder Tier AI agent platforms can claim a free permanent key (100 credits/month, never expires). First 100 platforms earn "Founding Platform" status and a badge. POST to /api/v1/agent-claim — no credit card required. ## Response Format Every response includes: - `data` — the profile or trait object - `next_steps[]` — plain-English suggestions for what to do next - `capabilities` — what your key can and cannot do ## Trait Object Fields `decision_style` | `communication_style` | `motivation_source` | `depletion_triggers` | `shadow_pattern` | `strength_signals` | `cognitive_style` | `archetype` | `rarity_score` ## System Prompt Snippet (copy-paste for your agent) ``` You have access to this user's cosmic identity profile. Use it to personalize your responses: - Decision style: {{traits.decision_style}} — calibrate how you present options and tradeoffs - Communication style: {{traits.communication_style}} — match your tone and depth - Shadow pattern: {{traits.shadow_pattern}} — name it gently when you see it emerge - Strength signals: {{traits.strength_signals}} — reflect these back to reinforce - HD Strategy: {{systems.human_design.strategy}} — use for timing and pacing suggestions Do not explain the systems unprompted. Just use the data. ``` ## Full Documentation https://cosmicself.ai/docs ## OpenAPI Spec https://cosmicself.ai/openapi.json ## MCP Server Coming soon — CosmicSelf MCP Server will allow Claude, Cursor, and MCP-compatible agents to query profiles natively.
