API Endpoint

POSThttps://api.segmind.com/v1/topaz-image-upscale

Parameters

imagerequired
string (uri)

Upload the image you want to upscale — works best with JPEGs or PNGs of portraits, products, or film frames.

enhance_modeloptional
string

Choose the enhancement type: Standard V2 for general use, High Fidelity V2 for detail-rich images, CGI for digital art.

Default: "Standard V2"
Allowed values :
"Standard V2""Low Resolution V2""CGI""High Fidelity V2""Text Refine"
face_enhancementoptional
boolean

Toggle to true if faces are present, great for portraits, character renders, and people in videos.

Default: false
face_enhancement_creativityoptional
number

Control artistic liberty in face enhancements, use 0 for realism, higher values for stylized or expressive looks.

Default: 0Range: 0 - 1
face_enhancement_strengthoptional
number

Set how sharp faces appear (0–1); 0.8 is ideal for natural skin textures, 1.0 for hyper-sharp details.

Default: 0.8Range: 0 - 1
output_formatoptional
string

Pick jpg for compression or png for lossless quality, PNG is better for sharp edges and transparency.

Default: "jpg"
Allowed values :
"jpg""png"
subject_detectionoptional
string

Focus enhancement on Foreground, Background, or All, use Foreground for products or portraits.

Allowed values :
"None""All""Foreground""Background"
upscale_factoroptional
string

Select 2x, 4x, or 6x to boost resolution — ideal for printing, zoom-ins, or turning 720p into 4K.

Allowed values :
"None""2x""4x""6x"

Response Type

Returns: Image

Asynchronous requests (v2)

Use Async for video, long-running (>~60s), or high-concurrency workloads; Sync is simplest for fast image & LLM calls. Async submits a request and you poll it to completion.

  1. 1
    POST /v2/topaz-image-upscale

    Submitreturns request_id, status_url, response_url

  2. 2
    GET /v2/requests/{id}/status

    Polluntil COMPLETED or FAILED

  3. 3
    GET /v2/requests/{id}

Status states

QUEUEDAccepted, waiting for a worker
PROCESSINGRunning on a worker
COMPLETEDDone — result body is ready
FAILEDErrored (incl. content/RAI blocks)
  • A FAILED request is served as HTTP 422 — the body still carries the error detail.
  • An unknown or expired request_id returns HTTP 404.
  • Results are retained for 1 hour, then expire.
  • Content / RAI blocks surface as FAILED, not a separate state.
  • Track completion by polling the status endpoint.
