The MM engine places orders automatically based on bookmaker odds. The client API provides read access to all trading activity. You do not place orders through this API — the engine does it for you.
Step 1: Verify your identity
Confirm your API key works and see your client info:
curl -H "X-API-Key: YOUR_API_KEY" \
https://mmapi.55-tech.com/api/v1/me
{
"client": "your-client",
"clientName": "Your Client Name",
"active": true
}
Step 2: View exchange orders
