API Endpoint

POSThttps://api.segmind.com/v1/segfit-v1.2

Parameters

model_imagerequired
string (uri)

Image of the outfit to be fitted. Example: a dress or suit.

base64optional
boolean

Return image as base64 string instead of URL.

Default: false
cn_endoptional
number

Endpoint for ControlNet's effect. Controls the model body shape, Higher the value, higher the control

Default: 0.35Range: 0 - 1
cn_strengthoptional
number

Strength of ControlNet's influence. Maintains the shape of the model.

Default: 0.35Range: 0 - 1
image_formatoptional
string

Output image format. 'PNG' is versatile, 'JPEG' compresses well.

Default: "png"
Allowed values :
"png""jpeg""webp"
image_qualityoptional
integer

Determine image quality (1-100). Use 100 for best detail, lower for smaller file size.

Default: 90Range: 1 - 100
model_typeoptional
string

Choose the generation model type. Use 'Speed' for fast results, 'Quality' for high detail.

Default: "balanced"
Allowed values :
"Speed""Balanced""Quality"
seedoptional
integer

Default: 42Range: -1 - 999999

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/segfit-v1.2

    Submitreturns request_id, status_url, response_url

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

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.
