How do I increase image resolution?

Use the "scale" integer min: 1 max: 4 flag in your requests to add a scale multiplier for increased resolution, as shown in the example below.

{
  "template": "MvqYnLpgQwQ0DPKxye",
	"formats": ["png", "jpg", "pdf", "webp"],
	"scale": 2,
	"modifications": {
    "objects": [
      {
        "name": "title",
        "text": "Hello World",
        "color": "#FF5733"
      },
      {
        "name": "avatar",
        "background-image": "https://example.com/photo.jpg"
      },
      {
        "name": "background",
        "background-color": "#d6d0e15e"
      }
    ]
  }
}

Note: When determining credit costs, the scale value will multiple the format count (e.g. "scale": 2 x "formats": ["png","jpg"] = 4 credits)
