Based on the scripts in your homelab, here are the Unifi API examples you're looking for. The code uses the **Network Integration API** (`/proxy/network/integration/v1/...`) and the **Static DNS API** (`/proxy/network/v2/api/...`).

### 1. Authentication
Both scripts use a Bearer-style header `X-API-Key`.
*   **Source:** `active/device_unifi/update_dns.py` & `active/aws_route53/unifi_to_aws.py`

```python
headers = {
    "Accept": "application/json",
    "X-API-Key": os.environ.get("API_KEY")
}
```

### 2. List All Sites
Used to find the `site_id` required for other calls.
*   **Endpoint:** `GET /proxy/network/integration/v1/sites`
*   **Source:** `active/device_unifi/update_dns.py`

```python
# Example from update_dns.py
response = requests.get(
    f"{UNIFI_API_ENDPOINT}/proxy/network/integration/v1/sites",
    headers={"X-API-Key": UNIFI_API_KEY},
    verify=False
)
sites = response.json().get("data")
```

### 3. Fetch Static DNS Devices
Returns a list of devices with hostnames and IPs.
*   **Endpoint:** `GET /proxy/network/v2/api/site/default/static-dns/devices`
*   **Source:** `active/aws_route53/unifi_to_aws.py`

```python
# Example from unifi_to_aws.py
devices_url = "https://10.1.0.1/proxy/network/v2/api/site/default/static-dns/devices"
devices_data = requests.get(devices_url, headers=headers, verify=False).json()
# Result format: [{"hostname": "...", "ip_address": "..."}, ...]
```

### 4. Fetch DNS Policies
Returns DNS records (policies) for a specific site.
*   **Endpoint:** `GET /proxy/network/integration/v1/sites/{site_id}/dns/policies`
*   **Source:** `active/device_unifi/update_dns.py` & `active/aws_route53/unifi_to_aws.py`

```python
# Example from unifi_to_aws.py
site_id = "88f7af54-98f8-306a-a1c7-c9349722b1f6"
policies_url = f"https://10.1.0.1/proxy/network/integration/v1/sites/{site_id}/dns/policies"
policies_data = requests.get(policies_url, headers=headers, verify=False).json()
# Result format: {"data": [{"domain": "...", "ipv4Address": "..."}, ...]}
```

### 5. DNS Record Structure
If you are creating or updating records (like in `unifi_to_aws.py`), the expected payload structure is:

```json
{
  "Action": "UPSERT",
  "ResourceRecordSet": {
    "Name": "mydevice.reeselink.com",
    "Type": "A",
    "TTL": 60,
    "ResourceRecords": [
      {"Value": "192.168.1.50"}
    ]
  }
}
```
