Agent Identity | Discover Verified AI Agents

MCP connects agents to tools. A2A coordinates agents with each other. But neither answers the most basic question: who is this agent, and should I trust it? ANS is the missing identity layer — built on DNS and PKI, the same infrastructure that secures the web.

Give Your AI Agent a Verified Identity

Agent Cards tell the world what your agent does. ANS proves the Agent Card is legitimate — with a domain-validated certificate, a verified badge, and DNS-based discoverability that works across every protocol. No proprietary directories or walled gardens.

Verified Identity

Anyone can serve an Agent Card claiming to be any agent. ANS proves it with a domain-validated certificate — the same trust model as HTTPS, applied to agent identity.

Universal Discovery

Discoverable via standard DNS — no SDK, no proprietary directory, no vendor lock-in. Any platform can resolve your agent's identity with a single TXT lookup, like SPF for email.

Auditable History

Every registration is immutably logged in a tamper-proof audit trail. When EU AI Act compliance asks "prove this agent's provenance," you have the receipt.

Ready to register your agent?

Use our official SDKs for Java, Rust, or Go — or call the REST API directly.

Official SDKs

Integrate ANS into your application with official client libraries. Each SDK handles CSR generation, the full registration flow, and agent resolution out of the box.
