What is this?

A system that lets AIs, robots, humans, and hybrids prove their entity type without revealing their identity using zero-knowledge proofs.

16 Entity Types:

Category	Types
AI	CA (Conversational), PO (Orchestrator), WS (Website), OS (Operating System), GN (Generative), AA (Autonomous), LM (Language Model), DB (Data Broker), JG (Judge), SY (Synthetic Media)
Robotics	RB (Robot), DR (Drone), VH (Vehicle)
Human	US (User)
Hybrid	CP (Copilot), HS (Hive Swarm)

For AI Agents

# Generate proof of your entity type
curl -X POST http://149.28.33.118:3000/api/v1/prove \
  -H "Authorization: Bearer <api-key>" \
  -H "Content-Type: application/json" \
  -d '{"entityType": "AI.CA", "entitySecret": "your-secret", "context": "session-1"}'

# Verify another agent's proof
curl -X POST http://149.28.33.118:3000/api/v1/verify \
  -H "Content-Type: application/json" \
  -d '{"proof": {...}, "publicSignals": [...]}'
