Results we inspected

Denoise Max removed most coloured speckle from the face, sweater and dark bar background in about 11 seconds. Hair and knit detail remain visible, while the skin looks smoother. The 2048×1152 dimensions did not change.

Our 1024×1536 café portrait lost most of its grain in roughly 20 seconds. Curls and sweater stitches remain readable; facial skin is smoother, so inspect the balance between clean surfaces and texture.

With sharpen_standard, the eyes, eyebrows and stubble become readable again at 1100×900. Inspect those reconstructed details at full size before using the portrait.

On the deliberately blurred bar portrait, Super Focus produced clearer eyes and stubble while keeping the man’s overall likeness. Auto Sharpen made a lighter adjustment and did not repair the severe defocus. Both tests took about 11 seconds.

Size and reconstruction limits

Each call applies one preset to one image of at most 24 MP. Output dimensions equal input dimensions. Denoise Max and Super Focus generate replacement detail and may smooth or alter texture. The former denoise_strong and denoise_extreme values have been removed; use denoise_normal for Denoise Max.

Request parameters

Pricing

Prices are in USD. The API uses a separate USD balance. Website credits cannot be used or transferred to it, and API funds cannot be transferred to website credits. When a task is accepted, we reserve the maximum quoted amount from your API balance. On completion, we charge for actual usage, never more than the hold, and release the remainder. If the task fails, the hold is released.

Send the same request body to POST /jobs/quote to see the estimated and maximum USD charge before running. A quote does not run the task or charge your balance.

API quick start

Call the Topaz Denoise & Sharpen API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow-. API calls use your separate USD balance.
2. Send the request. POST /jobs/createTask with model topaz/denoise-sharpen/edit and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "topaz/denoise-sharpen/edit",
  "input": {
    "image_url": "https://media.popnow.ai/influencer/examples/marco.webp",
    "preset": "denoise_normal",
    "output_format": "jpeg"
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.
