Introduction

Highflame's Agent Identity infrastructure is based on ZeroID which is our open-source identity infrastructure for autonomous agents. It gives each agent, service, MCP server, or application a stable identity, issues short-lived credentials, preserves delegation chains, and lets downstream systems verify who is acting and on whose authority.

For developers, the key idea is simple: stop treating agents like anonymous service accounts. Register them as first-class identities, issue scoped tokens, and preserve delegation across orchestrators and sub-agents.

What You Can Build With ZeroID

• Autonomous agents that authenticate as themselves with short-lived credentials instead of long-lived shared secrets.

• Multi-agent systems where orchestrators delegate only a subset of their scope to sub-agents.

• Identity-aware APIs that verify ZeroID JWTs and make authorization decisions from claims like sub, act.sub, delegation_depth, trust_level, and scopes.

• Operational controls such as revocation, credential policies, and real-time shutdown via Continuous Access Evaluation (CAE) signals.

Public and Admin Surfaces

ZeroID exposes two logical API surfaces:

• Public endpoints for token issuance, introspection, revocation, health, and discovery.

• Admin endpoints for identity registration, agent lifecycle, API keys, policies, signals, attestation, and proof-token workflows.

This separation is important when you design your deployment. Agents call the public surface directly. Platform and control-plane services call the admin surface.

When To Reach For ZeroID

Use ZeroID when you need any of the following:

• Per-agent identity instead of shared credentials

• Verifiable delegation between agents

• Scoped tokens that encode operational context

• Real-time revocation and incident response

• A standards-based identity layer for agentic systems

What's Next?

• Start with Quick Start to run ZeroID locally and register your first agent.

• Read Identity Model before designing your production tenant and identity taxonomy.

• Use SDK Overview if you plan to integrate ZeroID from Python or TypeScript first.
