Upscale an image to a higher resolution. The image can be provided either as a multipart form-data file upload or as a base64-encoded string in a JSON request.

Authentication: This endpoint accepts either a Bearer API key or a SIGN-IN-WITH-X header for x402 wallet-based authentication. The legacy X-Sign-In-With-X header is also accepted during migration. When using x402, a 402 Payment Required response indicates insufficient balance and includes top-up instructions.

application/jsonmultipart/form-data

Upscale an image to a higher resolution.

image · any string · 필수

The image to upscale. Can be either a file upload or a base64-encoded string. Image dimensions must be at least 65536 pixels and final dimensions after scaling must not exceed 16777216 pixels. File size must be less than 25MB.

creativity · number | null · 기본값: 0.01

How much detail and texture the upscaler adds. Higher values add more; lower values stay closer to the source. Clamped to the 0–0.02 range.

예시:

0.01

scale · number · 기본값: 2

The scale factor for upscaling the image. Must be either 2 or 4. A scale of 4 with large images will result in the scale being dynamically reduced to ensure the final image stays within the maximum size limits.

필수 범위: 2 <= x <= 4

예시:
