+# API Reference: Implementing Microsegmentation with Guardicore
+
+## Akamai Guardicore API
+
+```python
+import requests
+headers = {"Authorization": "Bearer <token>"}
+base = "https://guardicore.example.com/api/v3.0"
+# Get assets
+assets = requests.get(f"{base}/assets", headers=headers).json()
+# Get policies
+policies = requests.get(f"{base}/policies", headers=headers).json()
+# Get traffic map
+traffic = requests.get(f"{base}/connections", headers=headers,
+                       params={"from_time": "2024-01-01"}).json()
+```
+
+## Policy Modes
+
+| Mode | Description |
+|------|-------------|
+| Reveal | Monitor only, log violations |
+| Enforce | Block unauthorized traffic |

+| 3 | Any | Backend:* | Deny |
+| 4 | Backend | Any | Deny |
+
+## Segmentation Metrics
+
+| Metric | Target |
+|--------|--------|
+| Coverage rate | > 80% of flows |
+| Enforced policies | > 90% |
+| Cross-zone flows controlled | 100% |
+| Default deny coverage | All zones |
+
+## Traffic Analysis Fields
+
+| Field | Description |
+|-------|-------------|
+| `src_ip` | Source IP address |
+| `dst_ip` | Destination IP |
+| `dst_port` | Destination port |
+| `src_label` | Source workload label |
