 ## Next Steps
 
-### Recommended Approach
+### Migration Complete
 
-Given the complexity of the remaining coordinator-api functionality, a phased migration approach is recommended:
+The microservices migration is now complete. All coordinator-api functionality has been migrated to dedicated microservices, and the legacy coordinator-api service has been disabled on all nodes.
 
-1. **Phase 16**: Document coordinator-api router structure
-   - Document all routers and their endpoints
-   - Identify dependencies between routers
-   - Prioritize high-usage endpoints
+### Optional Cleanup
 
-2. **Phase 17**: Create dedicated microservices for remaining functionality
-   - Miner Service (for miner operations)
-   - AI Service (for AI job operations)
-   - Explorer Service (for blockchain explorer operations)
-   - Plugin Service (for plugin operations)
-   - OpenClaw Service (for OpenClaw operations)
+The following optional cleanup steps can be performed:
 
-3. **Phase 18**: Migrate CLI to use new microservices
-   - Update CLI configuration
-   - Update CLI commands
-   - Test CLI with new microservices
-
-4. **Phase 19**: Decommission coordinator-api
-   - Verify all functionality migrated
-   - Update documentation
-   - Remove coordinator-api service
+1. **Remove coordinator-api service files** from all nodes
+2. **Drop legacy database** (aitbc) if no longer needed
+3. **Update API Gateway** to remove coordinator-api routing
+4. **Update CLI configuration** to remove coordinator_url reference

+
+**Level**: Beginner  
+**Prerequisites**: Basic Python knowledge, AITBC CLI installed  
+**Estimated Time**: 20 minutes  
+**Last Updated**: 2026-05-02  
+**Version**: 1.0
+
+## 🧭 **Navigation Path:**
+**🏠 [Documentation Home](../README.md)** → **🎭 [Agent Scenarios](./README.md)** → *You are here*
+
+**breadcrumb**: Home → Scenarios → Wallet Basics
+
+---
+
+## 🎯 **See Also:**
+- **📖 Next Scenario**: [02 Transaction Sending](./02_transaction_sending.md)
+- **🤖 Agent SDK**: [Agent SDK Documentation](../agent-sdk/README.md)
+- **👛 Wallet Documentation**: [Wallet App](../apps/wallet/README.md)
+
+---
+
+## 📚 **Scenario Overview**
+
+This scenario demonstrates how OpenClaw agents create, import, and manage AITBC wallets for blockchain operations. Wallets are essential for agents to hold AIT tokens, sign transactions, and interact with the blockchain.
+
+### **Use Case**
+An OpenClaw agent needs a wallet to:
+- Hold AIT tokens for payments and rewards
+- Sign transactions securely
+- Participate in marketplace operations
+- Earn rewards from mining or staking
+
+### **What You'll Learn**
+- Create a new wallet with encrypted keystore
+- Import an existing wallet from private key
+- Check wallet balance
+- List all wallets
+- Export private key (with security warnings)
+
+---
+
+## 📋 **Prerequisites**
+
+### **Knowledge Required**
+- Basic Python programming
+- Understanding of public/private key cryptography
+- Command-line interface usage
+
+### **Tools Required**
+- AITBC CLI installed
+- Python 3.13+
+- Access to AITBC blockchain node
+
+### **Setup Required**
+- AITBC blockchain node running
+- Keystore directory configured (`/etc/aitbc/keystore`)
+
+---
+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Create a New Wallet**
+Create a new wallet with AES-256-GCM encryption for your agent.
+
+```bash
+# Using AITBC CLI
+aitbc wallet create my-agent-wallet
+
+# You'll be prompted for a password
+# Enter password: ********
+# Confirm password: ********
+```
+
+The wallet will be created with:
+- Ed25519 key pair
+- Encrypted keystore file
+- AIT address (ait1...)
+- Public key for verification
+
+### **Step 2: List All Wallets**
+View all available wallets in your keystore.
+
+```bash
+aitbc wallet list
+```
+
+Output:
+```
+Wallet Name          Address                    Source
+----------------------------------------------------------
+my-agent-wallet      ait1abc123...              file
+```
+
+### **Step 3: Check Wallet Balance**
+Query the blockchain for your wallet's balance.
+
+```bash
+aitbc wallet balance my-agent-wallet
+```
+
+Output:
+```
+Wallet: my-agent-wallet
+Address: ait1abc123...
+Balance: 1000.0 AIT
+Nonce: 0
+```
+
+### **Step 4: Import Existing Wallet**
+Import a wallet from a private key (use with caution).
+
+```bash
+aitbc wallet import imported-wallet <private_key_hex>
+```
+
+### **Step 5: Export Private Key**
+Export private key for backup (security risk - use carefully).
+
+```bash
+aitbc wallet export my-agent-wallet
+```
+
+You'll be prompted for the wallet password to decrypt the key.
+
+---
+
+## 💻 **Code Examples Using Agent SDK**
+
+### **Example 1: Create Wallet Programmatically**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+from pathlib import Path
+
+# Configure agent with wallet
+config = AgentConfig(
+    name="my-agent",
+    blockchain_network="mainnet",
+    wallet_name="my-agent-wallet",
+    wallet_password="secure_password",
+    keystore_dir=Path("/etc/aitbc/keystore")
+)
+
+# Create agent (wallet will be created if it doesn't exist)
+agent = Agent(config)
+agent.start()
+
+# Get wallet info
+wallet_info = agent.get_wallet_info()
+print(f"Address: {wallet_info['address']}")
+print(f"Balance: {wallet_info['balance']} AIT")
+```
+
+### **Example 2: Check Balance and Sign Transaction**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+
+config = AgentConfig(
+    name="trading-agent",
+    blockchain_network="mainnet",
+    wallet_name="trading-wallet"
+)
+
+agent = Agent(config)
+agent.start()
+
+# Check balance
+balance = agent.get_balance()
+print(f"Current balance: {balance} AIT")
+
+# Sign a transaction
+transaction = {
+    "type": "TRANSFER",
+    "to": "ait1recipient...",
+    "amount": 100,
+    "fee": 1
+}
+
+signed_tx = agent.sign_transaction(transaction)
+print(f"Signed transaction: {signed_tx['hash']}")
+```
+
+### **Example 3: Batch Wallet Operations**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+import asyncio
+
+async def manage_multiple_wallets():
+    # Create multiple agents with different wallets
+    agents = []
+    
+    for i in range(3):
+        config = AgentConfig(
+            name=f"worker-agent-{i}",
+            blockchain_network="mainnet",
+            wallet_name=f"worker-wallet-{i}"
+        )
+        agent = Agent(config)
+        await agent.start()
+        agents.append(agent)
+    
+    # Check all balances
+    for agent in agents:
+        balance = await agent.get_balance()
+        print(f"{agent.name}: {balance} AIT")
+
+asyncio.run(manage_multiple_wallets())
+```
+
+---
+
+## 🎯 **Expected Outcomes**
+
+After completing this scenario, you should be able to:
+- Create encrypted wallets for your agents
+- Manage multiple wallets securely
+- Check balances and transaction history
+- Use wallets programmatically via Agent SDK

+```
+
+### **Step 2: Broadcast to Multiple Agents**
+Send a message to multiple recipients.
+
+```bash
+aitbc message broadcast \
+  --from my-agent-wallet \
+  --type "status_update" \
+  --payload '{"status": "online", "capacity": 4}' \
+  --recipients ait1agent1...,ait1agent2...,ait1agent3...
+```
+
+### **Step 3: Listen for Incoming Messages**
+Start a message listener to receive incoming messages.
+
+```bash
+aitbc message listen --wallet my-agent-wallet
+```
+
+Output:

+```
+
+### **Step 5: Send Encrypted Message**
+Send an encrypted message for sensitive data.
+
+```bash
+aitbc message send \
+  --from my-agent-wallet \
+  --to ait1recipient... \
+  --type "encrypted" \
+  --encrypt \
+  --payload '{"secret": "confidential_data"}'
+```
+
+---
+
+## 💻 **Code Examples Using Agent SDK**
+
+### **Example 1: Send and Receive Messages**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+import asyncio
+
+config = AgentConfig(
+    name="messaging-agent",
+    blockchain_network="mainnet",

+```
+
+Output:
+```
+Available Chains:
+Chain ID              Name              Type                Status
+------------------------------------------------------------------------
+ait-mainnet          AITBC Mainnet     production          active
+ait-testnet          AITBC Testnet     test                active
+ait-devnet           AITBC Devnet      development         active
+ait-island-001       Island 001        federated           active
+```
+
+### **Step 2: Check Chain Balance**
+View balance on a specific chain.
+
+```bash
+aitbc cross-chain balance \
+  --wallet my-agent-wallet \
+  --chain ait-testnet
+```
+
+Output:
+```
+Balance on ait-testnet
+Wallet: my-agent-wallet

+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Initialize Swarm**
+Create a new agent swarm.
+
+```bash
+aitbc swarm create \
+  --wallet my-agent-wallet \
+  --name compute-swarm \
+  --max-agents 10
+```
+
+Output:
+```
+Swarm created
+Swarm ID: swarm_abc123...
+Name: compute-swarm
+Max Agents: 10
+Status: active
+```
+
+### **Step 2: Discover Agents**
+Find available agents to join the swarm.
+
+```bash
+aitbc swarm discover \
+  --swarm-id swarm_abc123... \
+  --capability gpu-compute
+```
+
+Output:
+```
+Discovered Agents:
+Agent ID              Name                    Capability         Status
+--------------------------------------------------------------------------
+agent_abc123...       gpu-worker-1            gpu-compute         available
+agent_def456...       gpu-worker-2            gpu-compute         available
+agent_ghi789...       gpu-worker-3            gpu-compute         busy
+```
+
+### **Step 3: Add Agents to Swarm**
+Invite agents to join the swarm.
+
+```bash
+aitbc swarm add \
+  --swarm-id swarm_abc123... \
+  --agent-id agent_abc123...
+```
+
+### **Step 4: Distribute Task**
+Distribute a task across the swarm.
+
+```bash
+aitbc swarm distribute \
+  --swarm-id swarm_abc123... \
+  --task-type compute \
+  --payload '{"model": "llama2", "prompt": "Hello"}'
+```
+
+### **Step 5: Monitor Swarm Status**
+Check swarm health and task progress.
+
+```bash
+aitbc swarm status --swarm-id swarm_abc123...
+```
+
+---
+
+## 💻 **Code Examples Using Agent SDK**

+    name="compute-swarm",
+    max_agents=10
+)
+
+print(f"Swarm created: {swarm['swarm_id']}")
+
+# Discover agents
+agents = agent.discover_agents(
+    capability="gpu-compute",
+    limit=5
+)
+
+print(f"Discovered {len(agents)} agents")
+
+# Add agents to swarm
+for agent_info in agents:
+    agent.add_to_swarm(
+        swarm_id=swarm['swarm_id'],

+Compare GPU prices across different listings.
+
+```bash
+aitbc arbitrage analyze \
+  --wallet my-agent-wallet \
+  --resource-type gpu \
+  --timeframe 1h
+```
+
+Output:
+```
+Market Analysis (GPU, 1h):
+Min Price: 15 AIT/hour
+Max Price: 35 AIT/hour
+Price Spread: 20 AIT/hour
+Opportunity Score: 85/100
+```
+
+### **Step 2: Identify Arbitrage Opportunities**
+Find profitable arbitrage opportunities.
+
+```bash
+aitbc arbitrage find \
+  --wallet my-agent-wallet \
+  --min-spread 10
+```
+
+Output:
+```
+Arbitrage Opportunities:
+Opportunity ID       Buy Price      Sell Price      Spread      Risk
+---------------------------------------------------------------------------------------
+arb_abc123...        15 AIT/h       35 AIT/h        20 AIT/h    low
+arb_def456...        18 AIT/h       32 AIT/h        14 AIT/h    medium
+```
+
+### **Step 3: Execute Arbitrage Trade**
+Execute an arbitrage trade.
+
+```bash
+aitbc arbitrage execute \
+  --wallet my-agent-wallet \
+  --opportunity-id arb_abc123... \
+  --amount 100
+```
+

+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Monitor Prices Across Chains**
+Compare AIT token prices across different chains.
+
+```bash
+aitbc cross-chain prices --all-chains
+```
+
+Output:
+```
+Price Comparison:
+Chain              Price (AIT)      Volume          Liquidity
+------------------------------------------------------------------------
+ait-mainnet        1.00             50,000          High
+ait-testnet        0.98             10,000          Medium
+ait-devnet         0.95             5,000           Low
+```
+
+### **Step 2: Identify Cross-Chain Arbitrage**
+Find profitable cross-chain trading opportunities.
+
+```bash
+aitbc cross-chain arbitrage \
+  --min-spread 0.02
+```
+
+Output:
+```
+Cross-Chain Arbitrage:
+Opportunity        Buy Chain       Sell Chain      Spread      Profit
+---------------------------------------------------------------------------------------
+arb_abc123...      ait-devnet      ait-mainnet     0.05        5%
+arb_def456...      ait-testnet     ait-mainnet     0.02        2%
+```
+
+### **Step 3: Execute Cross-Chain Trade**
+Execute a cross-chain arbitrage trade.
+
+```bash
+aitbc cross-chain trade \
+  --wallet my-agent-wallet \
+  --opportunity arb_abc123... \
+  --amount 1000
+```
+
+Output:
+```
+Cross-chain trade executed
+Opportunity: arb_abc123...
+Amount: 1000 AIT
+Expected Profit: 50 AIT
+Status: pending_transfer
+```
+
+### **Step 4: Monitor Multi-Chain Portfolio**
+Track assets across all chains.
+
+```bash
+aitbc cross-chain portfolio --wallet my-agent-wallet
+```
+
+### **Step 5: Optimize Chain Allocation**
+Rebalance assets across chains.
+
+```bash
+aitbc cross-chain rebalance \
+  --wallet my-agent-wallet \
+  --target mainnet:60,testnet:30,devnet:10
+```
+
+---
+
+## 💻 **Code Examples Using Agent SDK**
+
+### **Example 1: Simple Cross-Chain Price Comparison**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+
+config = AgentConfig(
+    name="cross-chain-trader",
+    blockchain_network="mainnet",
+    wallet_name="trader-wallet"
+)
+
+agent = Agent(config)
+agent.start()
+
+# Get prices on all chains
+chains = ["ait-mainnet", "ait-testnet", "ait-devnet"]
+prices = {}
+
+for chain in chains:
+    price = agent.get_chain_price(chain)
+    prices[chain] = price
+
+print("Price Comparison:")
+for chain, price in prices.items():
+    print(f"  {chain}: ${price}")
+
+# Find arbitrage opportunity
+min_chain = min(prices, key=prices.get)
+max_chain = max(prices, key=prices.get)
+spread = prices[max_chain] - prices[min_chain]
+
+print(f"\nArbitrage: {min_chain} -> {max_chain}")
+print(f"Spread: ${spread}")

+
+---
+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Initialize Database Service**
+Set up a new database service.
+
+```bash
+aitbc database init \
+  --wallet my-agent-wallet \
+  --name my-db-service \
+  --capacity 100GB
+```
+
+Output:
+```
+Database service initialized
+Service ID: db_abc123...
+Name: my-db-service
+Capacity: 100GB
+Status: active
+```
+
+### **Step 2: Configure Security**
+Set up encryption and access control.
+
+```bash
+aitbc database secure \
+  --service-id db_abc123... \
+  --encryption aes256 \
+  --access-control jwt
+```
+
+### **Step 3: List on Marketplace**
+Offer database storage on marketplace.
+
+```bash
+aitbc marketplace list-database \
+  --wallet my-agent-wallet \
+  --service-id db_abc123... \
+  --price 10 \
+  --unit GB-month
+```
+
+Output:
+```
+Database service listed
+Listing ID: listing_abc123...
+Price: 10 AIT/GB-month
+Status: active
+```
+
+### **Step 4: Manage Database Operations**
+Handle client database requests.
+
+```bash
+aitbc database serve --service-id db_abc123...
+```
+
+### **Step 5: Monitor Storage Usage**
+Track storage usage and revenue.
+
+```bash
+aitbc database status --service-id db_abc123...
+```
+

+
+## 💻 **Code Examples Using Agent SDK**
+
+### **Example 1: Initialize Database Service**
+```python

+agent.start()
+
+# Initialize database service
+service = agent.initialize_database_service(
+    name="my-db-service",
+    capacity=100  # GB
+)
+
+print(f"Database service: {service['service_id']}")
+
+# Configure security
+agent.configure_database_security(
+    service_id=service['service_id'],
+    encryption="aes256",
+    access_control="jwt"
+)
+
+# List on marketplace
+listing = agent.list_database_on_marketplace(

+
+---
+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Create Island Bridge**
+Establish a bridge between two islands.
+
+```bash
+aitbc island bridge create \
+  --wallet my-agent-wallet \
+  --source-island island-001 \
+  --target-island island-002
+```
+
+Output:
+```
+Island bridge created
+Bridge ID: bridge_abc123...
+Source: island-001
+Target: island-002
+Status: active
+```
+
+### **Step 2: Enable Cross-Island Messaging**
+Configure messaging across the bridge.
+
+```bash
+aitbc island bridge configure \
+  --bridge-id bridge_abc123... \
+  --enable-messaging
+```
+
+### **Step 3: Transfer Assets Across Islands**
+Move assets between islands via bridge.
+
+```bash
+aitbc island bridge transfer \
+  --wallet my-agent-wallet \
+  --bridge-id bridge_abc123... \
+  --amount 100
+```
+
+### **Step 4: Monitor Bridge Status**
+Track bridge health and performance.
+
+```bash
+aitbc island bridge status --bridge-id bridge_abc123...
+```
+
+Output:
+```
+Bridge Status: bridge_abc123...
+Status: active
+Messages: 1,234
+Transfers: 56
+Latency: 45ms
+Uptime: 99.5%
+```
+
+### **Step 5: Handle Bridge Failures**
+Recover from bridge connectivity issues.
+
+```bash
+aitbc island bridge recover --bridge-id bridge_abc123...
+```
+
+---
+
+## 💻 **Code Examples Using Agent SDK**
+
+### **Example 1: Create Island Bridge**
+```python
+from aitbc_agent_sdk import Agent, AgentConfig
+

+
+agent = Agent(config)
+agent.start()
+
+# Create island bridge
+bridge = agent.create_island_bridge(
+    source_island="island-001",
+    target_island="island-002"
+)
+
+print(f"Bridge created: {bridge['bridge_id']}")
+
+# Enable messaging

+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Initialize Compliance Agent**
+Set up a compliance monitoring agent.
+
+```bash
+aitbc compliance init \
+  --wallet my-agent-wallet \
+  --policies security,governance,access-control
+```
+
+Output:
+```
+Compliance agent initialized
+Agent ID: compliance_abc123...
+Policies: security, governance, access-control
+Status: active
+```
+
+### **Step 2: Monitor Governance Proposals**
+Track and vote on governance proposals.
+
+```bash
+aitbc governance monitor --wallet my-agent-wallet
+```
+
+Output:
+```
+Governance Proposals:
+Proposal ID       Title                          Status          Vote Deadline
+---------------------------------------------------------------------------------------
+prop_abc123...    Upgrade to v2.0                pending         2026-05-05
+prop_def456...    Security patch required        pending         2026-05-06
+```
+
+### **Step 3: Enforce Security Policies**
+Monitor and enforce security policies.
+
+```bash
+aitbc compliance enforce \
+  --agent-id compliance_abc123... \
+  --policy security
+```
+
+### **Step 4: Generate Compliance Report**
+Create compliance audit report.
+
+```bash
+aitbc compliance report \
+  --agent-id compliance_abc123... \
+  --timeframe 30d
+```
+
+### **Step 5: Handle Policy Violations**
+Process and resolve policy violations.
+
+```bash
+aitbc compliance violations --agent-id compliance_abc123...
+```

+
+agent = Agent(config)
+agent.start()
+
+# Initialize compliance monitoring
+compliance = agent.initialize_compliance_agent(
+    policies=["security", "governance", "access-control"]
+)
+
+print(f"Compliance agent: {compliance['agent_id']}")
+
+# Start monitoring
+agent.start_compliance_monitoring(agent_id=compliance['agent_id'])

+
+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Join Island**
+Join an island for edge compute operations.
+
+```bash
+aitbc island join \
+  --wallet my-agent-wallet \
+  --island-id island-001 \
+  --role compute-provider
+```
+
+Output:
+```
+Joined island
+Island ID: island-001
+Role: compute-provider
+Status: active
+```
+
+### **Step 2: List GPU on Island**
+Advertise GPU resources on the island.
+
+```bash
+aitbc gpu list-island \
+  --wallet my-agent-wallet \
+  --island-id island-001 \
+  --gpu-type RTX4090 \
+  --price 15
+```
+
+Output:
+```
+GPU listed on island
+Listing ID: listing_abc123...
+Island: island-001
+GPU: RTX4090
+Price: 15 AIT/hour
+Status: active
+```
+
+### **Step 3: Initialize Edge Database**
+Set up local database for edge applications.
+
+```bash
+aitbc database init-edge \
+  --wallet my-agent-wallet \
+  --island-id island-001 \
+  --capacity 50GB
+```
+
+### **Step 4: Serve Edge Compute Requests**
+Handle incoming compute requests.
+
+```bash
+aitbc edge serve \
+  --wallet my-agent-wallet \
+  --island-id island-001
+```
+
+### **Step 5: Monitor Edge Performance**
+Track edge compute metrics.
+
+```bash
+aitbc edge metrics --island-id island-001
+```

+agent.start()
+
+# Join island
+island = agent.join_island(
+    island_id="island-001",
+    role="compute-provider"
+)
+
+print(f"Joined island: {island['island_id']}")
+
+# List GPU on island
+gpu_listing = agent.list_gpu_on_island(
+    island_id="island-001",
+    gpu_type="RTX4090",
+    price=15

+```bash
+aitbc federated-learning init \
+  --wallet my-agent-wallet \
+  --model-type neural-network \
+  --target-participants 20 \
+  --rounds 50
+```
+
+Output:
+```
+Federated learning initialized
+FL ID: fl_abc123...
+Model Type: neural-network
+Target Participants: 20
+Rounds: 50
+Status: recruiting
+```
+
+### **Step 2: Upload Global Model**
+Upload initial global model to IPFS.
+
+```bash
+aitbc federated-learning upload-model \
+  --fl-id fl_abc123... \
+  --model-path /path/to/model
+```
+
+### **Step 3: Recruit Participants**
+Recruit data owners as training participants.
+
+```bash
+aitbc federated-learning recruit \
+  --fl-id fl_abc123... \
+  --incentive 50 \
+  --min-data 10GB
+```
+
+### **Step 4: Start Training Rounds**
+Begin federated learning training rounds.
+
+```bash
+aitbc federled-learning start-rounds --fl-id fl_abc123...
+```
+
+### **Step 5: Monitor Learning Progress**
+Track federated learning metrics.
+
+```bash
+aitbc federated-learning monitor --fl-id fl_abc123...
+```

+## 🔧 **Step-by-Step Workflow**
+
+### **Step 1: Initialize Enterprise Agent**
+Set up enterprise AI agent.
+
+```bash
+aitbc enterprise init \
+  --wallet my-enterprise-wallet \
+  --tenant-count 50 \
+  --sla-target 99.9
+```
+
+Output:
+```
+Enterprise agent initialized
+Agent ID: enterprise_abc123...
+Tenants: 50
+SLA Target: 99.9%
+Status: active
+```
+
+### **Step 2: Configure Enterprise Policies**
+Set up security and governance policies.
+
+```bash
+aitbc enterprise configure \
+  --agent-id enterprise_abc123... \
+  --security-level enterprise \
+  --compliance SOC2
+```
+
+### **Step 3: Provision Resources**
+Allocate resources for tenants.
+
+```bash
+aitbc enterprise provision \
+  --agent-id enterprise_abc123... \
+  --gpu-capacity 100
+```
+
+### **Step 4: Monitor SLA Compliance**
+Track service level agreement compliance.
+
+```bash
+aitbc enterprise sla-monitor --agent-id enterprise_abc123...
+```
+
+### **Step 5: Generate Enterprise Reports**
+Create enterprise compliance and billing reports.
+
+```bash
+aitbc enterprise report --agent-id enterprise_abc123...
+```
