```

## Python SDK

```python
from cloudflare import Cloudflare

client = Cloudflare(api_token="your-api-token")

# Create
app = client.spectrum.apps.create(
    zone_id="your-zone-id",
    protocol="tcp/22",

    origin_direct=["tcp://192.0.2.1:22"],
    ip_firewall=True,
    tls="off",
)

# List
apps = client.spectrum.apps.list(zone_id="your-zone-id")

# Get
app_details = client.spectrum.apps.get(zone_id="your-zone-id", app_id=app.id)

# Update
client.spectrum.apps.update(zone_id="your-zone-id", app_id=app.id, tls="full")

# Delete
client.spectrum.apps.delete(zone_id="your-zone-id", app_id=app.id)

# Analytics
analytics = client.spectrum.analytics.aggregate(
    zone_id="your-zone-id",
    metrics=["bytesIngress", "bytesEgress"],
    since=datetime.now() - timedelta(hours=1),
)
```

## Go SDK

```go
import "github.com/cloudflare/cloudflare-go"

api, _ := cloudflare.NewWithAPIToken("your-api-token")

// Create
app, _ := api.CreateSpectrumApplication(ctx, "zone-id", cloudflare.SpectrumApplication{
    Protocol:         "tcp/22",
    DNS:              cloudflare.SpectrumApplicationDNS{Type: "CNAME", Name: "ssh.example.com"},
    OriginDirect:     []string{"tcp://192.0.2.1:22"},
    IPFirewall:       true,
    ArgoSmartRouting: true,
})

// List
apps, _ := api.SpectrumApplications(ctx, "zone-id")

// Delete
_ = api.DeleteSpectrumApplication(ctx, "zone-id", app.ID)
```

## Analytics API

**Metrics:**
- `bytesIngress` - Bytes received from clients
- `bytesEgress` - Bytes sent to clients
- `count` - Number of connections
- `duration` - Connection duration (seconds)

**Dimensions:**
- `event` - Connection event type
- `appID` - Spectrum application ID
- `coloName` - Datacenter name
- `ipVersion` - IPv4 or IPv6

**Example:**
```bash
curl "https://api.cloudflare.com/client/v4/zones/$ZONE_ID/spectrum/analytics/aggregate/current?metrics=bytesIngress,bytesEgress,count&dimensions=appID" \
  --header "Authorization: Bearer $CLOUDFLARE_API_TOKEN"
```
