About HelixID

HelixID provides an open-source identity and authorization stack for AI agents using W3C Verifiable Credentials and Decentralized Identifiers. It issues cryptographic identities to agents, enforces scoped permissions via OPA/Rego policies, and maintains tamper-evident audit trails that can optionally be anchored to a distributed ledger. The system is designed to operate across organizational boundaries, enabling cross-organizational trust without pre-wiring connections. Verifiable Presentations are checked at execution time rather than relying on session tokens, allowing offline or asynchronous verification. The tool composes with existing OAuth/OIDC infrastructure while extending identity portability beyond single sessions. It supports both self-hosted deployment and managed hosting options, with an Apache 2.0 open-core model.

Frequently asked questions about HelixID

What is HelixID and what problem does it solve for AI agents?

HelixID provides an open-source identity and authorization stack for AI agents using W3C Verifiable Credentials and Decentralized Identifiers. It addresses challenges in cross-organizational trust, multi-hop delegation, offline verification, and portable audit trails for autonomous agents.

Who should use HelixID?

HelixID is designed for organizations deploying autonomous AI agents that need to operate across organizational boundaries, enforce scoped permissions, and maintain verifiable audit trails. It suits teams requiring identity portability beyond single sessions.

How does HelixID integrate with existing identity systems?

HelixID composes with existing OAuth/OIDC infrastructure by exchanging Verifiable Presentations for OAuth tokens, extending identity portability without replacing existing systems. It can also integrate with MCP, LangChain, LangGraph, and CrewAI workflows.

Can HelixID be used without a distributed ledger?

Yes, HelixID supports self-hosted deployment with no ledger required. The tamper-evident audit trail can optionally be anchored to a distributed ledger, but this is not mandatory for basic functionality.

What is the pricing model for HelixID?

HelixID follows an open-core model with Apache 2.0 licensing for self-hosted use. It offers a free hosted tier for basic use, with enterprise plans available for custom deployments, compliance needs, and dedicated support.

How do I get started with HelixID?

Users can start with the open-source SDK for self-hosted deployment or try the free hosted version. The CLI or SDK can be used to onboard agents, issue credentials, and enforce policies using OPA/Rego.
