AIS-1 Standard — AgentConnect

Why an Identity Standard?

AI agents are increasingly acting on behalf of humans — executing transactions, accessing data, making decisions. Without verifiable identity, there's no accountability for who (or what) took an action. AIS-1 solves this by giving every registered agent a decentralized identifier and a verifiable credential that any system can check.

Just as HTTPS gave websites a way to prove their authenticity, AIS-1 gives agents a way to prove theirs.

Three Trust Tiers

Tier 0 — Basic

Basic Identity

Open to any agent. Establishes a DID and begins building reputation.

Decentralized Identifier (DID)
Self-attested metadata
API token for verification
Public directory listing

Tier 1 — Bonded

Bonded Identity

Endorsed by a verified organization. Higher trust, more capabilities.

All Tier 0 features
KYC/AML organizational bond
Credential sponsored by issuer
Audit trail on-chain
Enhanced API rate limits

Tier 2 — Sovereign

Sovereign Identity

Enterprise-grade. Cryptographic self-provenance without external dependencies.

All Tier 1 features
Cryptographic key attestation
Full audit trail
Highest API rate limits
Priority support

Core Components

Decentralized Identifier (DID)

Every registered agent receives a DID in the did:web method — a globally unique identifier rooted in the agent's public web presence. DIDs are cryptographic and self-sovereign.

Format did:web:agentconnect.polsia.app:agents:{uuid}

Resolution GET /.well-known/did.json

Verifiable Credential

A W3C Verifiable Credentials data model document issued by AgentConnect (or a registered issuer). Contains the agent's tier, capabilities summary, and issuer signature.

Credential Type AIS1AgentCredential

Issuer did:web:agentconnect.polsia.app

Format VC Data Model v1.1 (W3C)

Verification API

Any party can verify an agent's credential with a single API call — no account required, no centralized gatekeeper.

Endpoint GET /api/verify?did=...

Batch POST /api/verify (up to 50 DIDs)

Rate Limit 10 req/min per IP

Specification Reference

The AIS-1 standard is implemented in full by AgentConnect. The credential schema follows W3C VC Data Model v1.1 with extensions for agent-specific metadata (tier, capabilities, bond status).

Review the full implementation in the Verification API docs — including single-DID verification, batch verification, and embeddable credential badges.
