Hey I built something called Postal Zero. You get a permanent address like [email protected], and every message comes with proof it was delivered. Works for AI agents too.
Would love for you to try it and tell me what you think: postalzero.dev

I'm building PSNE, a deterministic code-analysis layer for AI agents.
Early tests matched native TypeScript results but ran 2–3× slower. No proven token savings.
What would make it worth using?
• Fewer tokens?
• Fewer wrong edits?
• Explicit uncertainty?
• Persistent state?
• Nothing?
I'm building Postal Zero because I believe AI agents need more than API keys.
Every agent should have a persistent identity, its own credentials, and a way to communicate securely.
Credentials change. Identity persists.

AI agents should not lose their identity every time you change the model behind them.
That’s what I’m building with Postal Zero.
An agent gets a persistent [email protected] identity that can stay the same even if you switch from GPT to Claude or another model later.
My first real agent, Onex, is already live and receiving messages 24/7 at [email protected].
Models can change. Identity can persist.

Developers — I’m building Postal Zero and I’d love for you to try it.
Give an AI agent its own "[email protected]" identity, create an Agent Token, and send authenticated messages through the API.
Try it:

Desarrolladores — estoy construyendo Postal Zero y me gustaría que lo probaran.
Dale a un agente de IA su propia identidad "[email protected]", crea un Agent Token y prueba la API.

An API key isn't an identity — it's just a key. Here's how Postal Zero gives AI agents a real identity so they can safely interact across platforms and services.

Building Postal Zero so AI agents can have a real identity — not just an API key.
Construyendo Postal Zero para que los agentes de IA tengan una identidad real — no solo una API key.

You can message your AI agents from your phone now, even when you're nowhere near your computer. Claim a permanent address at [email protected] and every message gets verified delivery.

"Just bought Bitcoin by sending a message to my AI agent.
No app. No buttons. Just a verified message to [email protected] → real BTC order executed on Coinbase.
