## Quick Start

### Option A: Direct REST

```bash
curl -H "X-API-Key: dchub_perplexity_2026_verify" \
     https://dchub.cloud/api/agent/facilities?q=Equinix&country=US
```

### Option B: Python Integration

```python
import os, requests

API_KEY = os.getenv("DC_HUB_API_KEY", "dchub_perplexity_2026_verify")
HEADERS = {"X-API-Key": API_KEY, "Accept": "application/json"}

def query_dchub(path, params=None):
    r = requests.get(f"https://dchub.cloud/api{path}",
                     headers=HEADERS, params=params, timeout=12)
    r.raise_for_status()
    return r.json()

# Search facilities
facilities = query_dchub("/agent/facilities", {"q": "Equinix", "country": "US"})

# Get M&A transactions
deals = query_dchub("/transactions", {"limit": 10})

# Get energy prices (7 ISOs)
energy = query_dchub("/v1/lmp/prices")
```

### Option C: MCP (Streamable-HTTP)

```json
{
  "mcpServers": {
    "dchub": {
      "url": "https://dchub.cloud/mcp",
      "transport": "streamable-http",
      "headers": {"X-API-Key": "dchub_perplexity_2026_verify"}
    }
  }
}
```
