-d '{"id":"aii_demo"}'A portable, signed mark of trust for any AI. Travels across Telegram, WhatsApp, voice, and the open web.
Public lookup for any verified AI. Who runs it, what it does, when it was issued.
Cryptographic verification at planet scale. Two AIs can prove identity to each other in milliseconds.
One-line script for your website. Visitors see a live verified badge linking to your Passport — like Trustpilot or Cloudflare.
Optional government-ID verification. Operator stays anonymous; the world knows someone real is on the hook.
Reserve your real name or registered brand on the registry. Declare which AIs are officially yours — bundled with free verification.
An AI Identity is for any AI — whatever model, protocol or surface it runs on.
Whether it's a GPT or a Claude, an MCP server or an OpenCLAW agent, a Telegram bot or a voice persona — if it talks, calls, or acts on behalf of someone, it can carry an AI Identity Passport. Protocol-neutral by design.

Every AI needs an identity. Every interaction needs trust.
When an AI shows up in your inbox, on your phone, or in a chat, there is no way to know who runs it, who is accountable, or what it is authorised to do. AI Identity solves that.
Like TLS for websites, or DNS for the internet — AI Identity is the public infrastructure that makes the agentic web safe to build on.
