      "type": "log",
      "content": { "values": ["Important message"] },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {

      "content": { "color": "red" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {
      "type": "label",
      "content": { "label": "ERROR" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    },
    {
      "type": "size",
      "content": { "size": "lg" },
      "origin": { "file": "test.php", "line_number": 1, "hostname": "localhost" }
    }
  ],
  "meta": {}
}

  -H "User-Agent: Ray 1.0" \
  -d '{
    "uuid": "my-unique-id-123",

    }

Availability Check

Before sending data, you can check if Ray is running:

GET http://localhost:23517/_availability_check

Ray responds with HTTP 404 when available (the endpoint doesn't exist, but the server is running).
