1 credit = $0.01. A task holds the highest possible charge when it is accepted and settles the real amount when it finishes, rounded up to whole credits; failed tasks are not charged. Ask POST /api/v1/jobs/quote for the exact figure before you run.

Upscale Image

popnow/image-upscaler-v1/upscale

Price

Option	Credits (per image)	US dollars
`Default`	1.8	$0.018

Parameters

Field	Type	Default	Allowed	What it does
`image_url`Required	`string`	—	—	The image to enlarge. Its framing and aspect ratio are kept; only the resolution goes up.
`resolution`Optional	`string`	`4k`	2k, 4k, 8k	Output size tier: a pixel budget of about 4 (2k), 17 (4k) or 67 (8k) megapixels, with the aspect ratio kept. A tier below the source's pixel count scales the image down. All three tiers cost the same.
`output_format`Optional	`string`	`jpeg`	jpeg, png, webp	File type of the returned image. png is lossless but several times larger than jpeg.

Example request

This request runs as it is; any field you leave out uses its default. Put your key in POPNOW_API_KEY first.

The example uses PopNow sample files in image_url. Replace them with your own public HTTPS links, uploads or saved assets.
