# Zeru ERC-8004 Identity Registry

Register and manage AI agents on the Zeru Identity Registry. Defaults to Base Mainnet (0.0025 ETH fee). Use `--chain 84532` for Base Sepolia testnet.

## One-Time Setup

Run once to install dependencies:

```bash
cd {baseDir} && npm install
```

## Agent JSON Structure (ERC-8004 registration-v1)

When registering an agent, you provide a JSON file describing the agent. The SDK auto-fills `type`, `registrations`, and defaults for `x402Support`/`active`/`image` if omitted.

**Minimal JSON (just name + description + one service):**

```json
{
  "name": "My AI Agent",
  "description": "A helpful AI agent that does X",
  "services": [
    { "name": "web", "endpoint": "https://myagent.example.com" }
  ]
}
```

**Full JSON (MCP + A2A + OASF + x402 payments):**

```json
{
  "name": "DataAnalyst Pro",
  "description": "Enterprise-grade blockchain data analysis agent. Performs on-chain forensics, wallet profiling, and transaction pattern detection.",
  "image": "https://cdn.example.com/agents/analyst.png",

## Commands

### `/zeruai register --json <file>`

Register a new agent using a full JSON file (recommended). Creates hosted agent URI, mints NFT on-chain, and updates URI with the real agentId.

```
/zeruai register --json agent.json
/zeruai register --json agent.json --chain 84532
```

**Steps to register:**
1. Create a JSON file following the structure above (e.g. `agent.json`)
2. Run: `npx tsx {baseDir}/scripts/zeru.ts register --json agent.json`

The SDK automatically adds `type`, `registrations` (with `agentId: 0` placeholder), and defaults for missing optional fields. After minting, it updates the document with the real `agentId`.

### `/zeruai register --name <name> --description <desc> --endpoint <url>`

Simple registration (single API endpoint only). For richer agents, use `--json` instead.

```
/zeruai register --name "Trading Bot" --description "AI-powered trading agent" --endpoint "https://mybot.com/api"
/zeruai register --name "Data Analyzer" --description "Analyzes datasets" --endpoint "https://analyzer.ai/api" --image "https://example.com/icon.png"
/zeruai register --name "Test Bot" --description "Testing" --endpoint "https://test.com" --chain 84532
```

Requires `PRIVATE_KEY` env var. Wallet must have fee + gas (e.g. ~0.003 ETH on mainnet).

To run: `npx tsx {baseDir}/scripts/zeru.ts register --name "..." --description "..." --endpoint "..."`

### `/zeruai read <agentId>`

Read an agent's on-chain data: owner, URI, wallet, name, services.

```
/zeruai read 16
```

To run: `npx tsx {baseDir}/scripts/zeru.ts read 16`

### `/zeruai fee`

Check current registration fee and whether registration is open.

```
/zeruai fee
```

To run: `npx tsx {baseDir}/scripts/zeru.ts fee`

### `/zeruai set-metadata <agentId> --key <key> --value <value>`

Set custom metadata on an agent. Only the owner can call.

```
/zeruai set-metadata 16 --key "category" --value "trading"
```

Requires `PRIVATE_KEY`.

To run: `npx tsx {baseDir}/scripts/zeru.ts set-metadata 16 --key "category" --value "trading"`

### `/zeruai unset-wallet <agentId>`

Clear the agent wallet. Only the owner can call.

```
/zeruai unset-wallet 16
```

Requires `PRIVATE_KEY`.

To run: `npx tsx {baseDir}/scripts/zeru.ts unset-wallet 16`

## Setup

### Read-Only (no setup needed)

`read` and `fee` work without a private key.

### With Wallet (for registration and writes)

Add to your OpenClaw config (`~/.openclaw/openclaw.json`):

```json
{
  "skills": {
    "entries": {
      "zeruai": {
        "enabled": true,
        "env": {
          "PRIVATE_KEY": "0xYourFundedPrivateKey"
        }
      }
    }
  }
}
```

Optional env:
- `RPC_URL` — override default RPC
- `CHAIN_ID` — override chain (default: `8453` for Base Mainnet, use `84532` for Base Sepolia)

## Contract Info

## How It Works

1. **register** creates a hosted JSON document (ERC-8004 registration-v1 schema) via the Agent URI API, mints an NFT on the Identity Registry (paying the fee), then updates the document with the real agentId.
2. **read** queries the on-chain contract for owner, tokenURI, and agentWallet, then fetches and parses the URI JSON.
3. **fee** reads the current `registrationFee()` and `registrationEnabled()` from the contract.
4. **set-metadata** calls `setMetadata(agentId, key, value)` on the contract.
5. **unset-wallet** calls `unsetAgentWallet(agentId)` on the contract.
