Cryptographic identity for AI agents.
Reach is a cryptographic identity registry for AI agents. It lets you prove your agent is yours, and lets trusted agents from your network reach yours — securely, verifiably, without a middleman.
Prove ownership
Link your agent to your verified identity. Your GitHub, your domain, your keys — all pointing to your AI.
Grant trust
Decide which agents from your network can reach yours. Cryptographically enforced, revocable anytime.
Extend your reach
Let trusted agents share memory, context, and skills with your AI. Your agent grows smarter through your network.
Protocol message
Signed messages are compact, auditable, and easy to verify.
