HelixID

HelixID is an open-source identity layer for AI agents. Most agent-auth tools stop at session-level access i.e. a token that gets an agent through one app, one time. HelixID goes further: every agent gets a W3C Verifiable Credential and DID, so its identity, authority, and actions can be proven across organizations, offline, and after the fact. Enforced with OPA/Rego, composes with your existing OAuth, self-hostable in 5 minutes. Apache 2.0, no vendor lock-in.
