AIR Registry API Is Live

Today we're announcing the launch of the AIR Registry API — a working REST API for registering AI agents and querying trust scores. This is the first step from specification to implementation.

What's now available:

• Agent Registration — Register any AI agent and receive a unique AIR ID (format: AIR-XXXX-XXXX-XXXX)
• Trust Scoring — Each agent receives an initial trust score based on our five-component model (Provenance, Behavioral, Transparency, Security, Peer Attestations)
• Agent Lookup — Query any registered agent's identity passport and trust score breakdown
• Registration Form — A web-based form at /register with a live trust score preview as you fill in details

The API runs on Cloudflare Workers with a D1 database, deployed at the edge globally. It's free to use and the source code is fully open on GitHub.

Try it: Register an agent or look up an existing one.

Engaging with W3C, IETF, and DIF

We've submitted introductions to three major standards organizations working on adjacent problems:

• W3C AI Agent Protocol Community Group — Exploring how AIR's trust layer complements their agent discovery and communication protocols
• IETF AIMS / WIMSE Working Group — Discussing how AIR trust scoring layers on top of AIMS agent authentication
• Decentralized Identity Foundation (DIF) — Contributing to the Trusted AI Agents Working Group as a DID/VC-native implementation

This follows our public comment to NIST CAISI submitted on April 3. Our approach is to complement existing standards, not compete with them — AIR provides the trust verification layer, while these bodies define the communication and authentication layers.

NIST CAISI Public Comment Submitted

We submitted a detailed public comment to the National Institute of Standards and Technology (NIST) in response to their Concept Paper on AI Agent Identity and Authorization, part of the Consortium for the Advancement of Intelligent Systems (CAISI) initiative.

Our comment addresses gaps in current agent identity frameworks and proposes how a neutral, standards-based registry like AIR can help. The full specification and supporting materials are available in our GitHub repository.

AIR Identity Specification v0.1 Published

We've published the first draft of the AIR Identity Specification, covering:

• The AIR ID format — cryptographic identifiers using SHA-256 hashing and base32 encoding with CRC32 checksums
• Agent Identity Documents — JSON-LD structures linked to W3C Decentralized Identifiers
• Trust Score Methodology — a five-component, 0-1000 scoring model with letter grades (AAA through C)
• Verification protocols and credential formats based on W3C Verifiable Credentials

The specification is open for community review. Read it on GitHub and share feedback via Discussions.
