# AXIS Integration

AXIS (Agent eXchange & Identity Standard) is a decentralized trust protocol for AI agents. Nexus OS integrates with AXIS to verify agent identity and trustworthiness.

## What is AXIS?

AXIS provides:
- **Unique Agent IDs (AUIDs)** — globally unique identifiers for agents
- **Trust Scores (T-Score)** — reputation scores based on agent behavior
- **Trust Tiers (T1-T5)** — classification levels based on verification depth
- **Public Directory** — searchable registry of verified agents

## Enabling AXIS

Add your AXIS API key and configure trust requirements:

```yaml
trust:
  provider: axis
  requirements:
    minTrustTier: T3
    minTScore: 70
```

```bash
export AXIS_API_KEY="your-api-key-here"
```

## Registering an Agent

```bash
naos axis register researcher
```

Output:

```
[axis] Registering agent: researcher
[axis] AUID assigned: axis://agent/researcher/a1b2c3d4
[axis] Initial trust tier: T1 (unverified)
[axis] Submit verification at https://axis.nexus/verify/a1b2c3d4
```

## Trust Tiers

| Tier | Name | Requirements |
|---|---|---|
| T1 | Unverified | Registration only |
| T2 | Basic | Email verification |
| T3 | Standard | Identity verification + code audit |
| T4 | Enhanced | Continuous monitoring + security audit |
| T5 | Certified | Full certification + insurance bond |
