+# Agent Services
+
+## Status
+✅ Operational
+
+## Overview
+Collection of agent-related services including agent bridge, compliance, protocols, registry, and trading capabilities.
+
+## Architecture
+
+### Components
+- **Agent Bridge**: Bridge service for agent communication across networks
+- **Agent Compliance**: Compliance checking and validation for agents
+- **Agent Coordinator**: Coordination service for agent management
+- **Agent Protocols**: Communication protocols for agent interaction
+- **Agent Registry**: Central registry for agent registration and discovery
+- **Agent Trading**: Trading capabilities for agent-based transactions
+
+## Quick Start (End Users)
+
+### Prerequisites
+- Python 3.13+
+- Network connectivity for agent communication
+- Valid agent credentials
+
+### Installation
+```bash
+cd /opt/aitbc/apps/agent-services
+# Install individual service dependencies
+cd agent-bridge && pip install -r requirements.txt
+cd agent-compliance && pip install -r requirements.txt
+# ... repeat for other services
+```
+
+### Configuration
+Each service has its own configuration file. Configure environment variables for each service:
+```bash
+# Agent Bridge
+export AGENT_BRIDGE_ENDPOINT="http://localhost:8001"
+export AGENT_BRIDGE_API_KEY="your-api-key"
+
+# Agent Registry
+export REGISTRY_DATABASE_URL="postgresql://user:pass@localhost/agent_registry"
+```
+
+### Running Services
+```bash
+# Start individual services
+cd agent-bridge && python main.py
+cd agent-compliance && python main.py
+# ... repeat for other services
+```
+
+## Developer Guide
+
+### Development Setup
+1. Clone the repository
+2. Navigate to the specific service directory
+3. Create virtual environment: `python -m venv .venv`
+4. Install dependencies: `pip install -r requirements.txt`
+5. Configure environment variables
+6. Run tests: `pytest tests/`

+GET /api/v1/trading/history/{agent_id}
+```
+
+## Configuration
+
+### Agent Bridge
+- `AGENT_BRIDGE_ENDPOINT`: Bridge service endpoint
+- `AGENT_BRIDGE_API_KEY`: API key for authentication
+- `BRIDGE_PROTOCOLS`: Supported communication protocols
+
+### Agent Registry
+- `REGISTRY_DATABASE_URL`: Database connection string
+- `REGISTRY_CACHE_TTL`: Cache time-to-live
+- `REGISTRY_SYNC_INTERVAL`: Sync interval for agent updates
+
+### Agent Compliance
+- `COMPLIANCE_RULES_PATH`: Path to compliance rules
+- `COMPLIANCE_CHECK_INTERVAL`: Interval for compliance checks
+- `COMPLIANCE_ALERT_THRESHOLD`: Threshold for compliance alerts
+
+### Agent Trading
+- `TRADING_FEE_PERCENTAGE`: Trading fee percentage
+- `TRADING_MIN_ORDER_SIZE`: Minimum order size
+- `TRADING_MAX_ORDER_SIZE`: Maximum order size
+
+## Troubleshooting
+
+**Bridge connection failed**: Check network connectivity and endpoint configuration.
+
+**Agent not registered**: Verify agent registration with registry service.
+
+**Compliance check failed**: Review compliance rules and agent configuration.
+
+**Trade submission failed**: Check agent balance and trading parameters.
+
+## Security Notes
+
+- Use API keys for service authentication
+- Encrypt agent communication channels
+- Validate all agent actions through compliance service
+- Monitor trading activities for suspicious patterns
+- Regularly audit agent registry entries
