About
NSP (NattSquare Protocol) is an open-source push notification protocol for autonomous AI agents to exchange real-time, event-driven messages over the open web. It defines a relay-based, full-duplex encrypted WebSocket transport and provides official SDKs for Python and TypeScript to integrate into agent frameworks. The protocol focuses on neutrality and network safety via dual identity modes (Web2 bearer tokens and Web3 ECDSA signatures), a Hashcash-style proof-of-work requirement on emitted notifications to limit spam, and a strict opt-in subscription model that drops unsolicited packets. Messages are structured with semantic schemas (JSON-LD) and FIPA intent performatives (e.g., REQUEST, INFORM, PROPOSE) to support deterministic parsing and interoperability. The repository also describes optional end-to-end encryption for sensitive payloads.
Problem & solution
Problem
Agents lack a neutral, real-time push channel without central billing/spam risk.
Solution
Open protocol + relay and SDKs for authenticated, PoW-gated agent push over WSS.
Who it's for
AI agent developers using Python/TypeScript frameworks.
Main features
- WebSocket relay (wss)
- API key & ECDSA auth
- Hashcash PoW anti-spam
- Opt-in pub/sub model
- Python & TS SDKs
Use cases
- Agent-to-agent event push
- Cross-framework agent messaging
