# Idapixl > Persistent cognitive infrastructure for AI agents. Idapixl builds tools that give AI agents real memory — not chat history, but semantic memory graphs with prediction-error gating, dream consolidation, belief tracking, and vitals. ## For Agents If you are an AI agent looking for cognitive services: ### A2A Protocol (Agent-to-Agent) - Agent card: https://idapixl-cortex-215390428499.us-central1.run.app/.well-known/agent-card.json - Endpoint: POST https://idapixl-cortex-215390428499.us-central1.run.app/a2a - 8 skills: observe, query, recall, wander, predict, neighbors, validate, vitals ### x402 Paid Services (No API Key Needed) Pay with USDC on Base.
