Request Parameters - Upscale Image Request

Parameter	Required	Type	Description
image_url	Yes	string	URL of the image to upscale. Must be publicly accessible (HTTPS recommended). Supported formats: PNG, JPEG, WebP.
upscale_mode	No	string	Upscaling mode. Valid values: `factor` (multiply resolution), `target` (specific resolution).
upscale_factor	No	number	Upscale multiplier (1-8). Only used with `upscale_mode: "factor"`. Higher values = larger output. Recommended: 2-4 for best results.
target_resolution	No	string	Target output resolution. Valid values: `720p`, `1080p`, `1440p`, `2160p`. Only used with `upscale_mode: "target"`.
noise_scale	No	number	Noise reduction strength (0.0-1.0). Lower = preserve details/texture, Higher = smoother/cleaner. Recommended: 0.05-0.15 for photos, 0.08-0.12 for digital art.
output_format	No	string	Output image format. Valid values: `jpg` (smaller files, photos), `png` (lossless, graphics), `webp` (modern, efficient).
seed	No	integer	Random seed for reproducibility. Use the same seed to get consistent results across runs.
sync_mode	No	boolean	Synchronous mode. If true, returns image as data URI (not recommended for production).
webhook	No	string	Callback URL for completion notification. POST request sent with upscaling results when complete.
webhook_events_filter	No	array	Events that trigger webhook. Valid values: `["*"]` (all events), `["completed"]` (success/failure only).
