Recraft Crisp Upscale: one image URL in, a sharper image at 2× the width and height out with the content unchanged — for product photos, text banners, screenshots and design assets.

Production guidance

For production, pass callback.url at the top level of the request body so HiAPI can notify your service when the task reaches a terminal state.
GET /v1/tasks/:id is better for local debugging, low-volume jobs, or fallback reconciliation if a callback is missed.
Result URLs expire — copy the output to your own storage once the task succeeds.
Validate the input format and size (up to 10MB) before submitting; requests beyond the limits fail.

Best suited for

Product photos

Double low-resolution product shots for listings and hero images.

image_url

Banners & screenshots with text

Letter shapes stay the same while edges sharpen — no new text is invented.

image_url

Assets & textures

Materials, textures and design assets keep continuous detail at 2×.

Request body

{
  "model": "recraft/crisp-upscale",
  "input": {
    "image_url": "https://dev-static.hiapi.ai/model-onboarding/recraft-crisp-upscale/2026/10/16/1792139966228-25c647f84f4600ac-c1-ceramic-640.jpg"
  }
}

Getting the result

The response returns a taskId immediately without waiting for generation to finish.
In production, prefer waiting for callback.url to receive the terminal notification. For local debugging, poll GET /v1/tasks/:id.
When status=success, download the upscaled JPEG image from output[].url.
When status=fail, fix the request based on the returned error instead of retrying the same invalid payload.
