API Endpoint

POSThttps://api.segmind.com/v1/automatic-mask-generator

Parameters

imagerequired
string (uri)

Upload your input image

promptrequired
string

Prompt to render

base64optional
boolean

Base64 encoding of the output image.

Default: false
grow_maskoptional
integer

Selectively expand image regions

Default: 10Range: 0 - 100
invert_maskoptional
boolean

Refers to inverting the mask.

Default: false
return_alphaoptional
boolean

Check this to obtain alpha mask image

Default: false
return_maskoptional
boolean

Check this to obtain the mask as the output.

Default: true
seedoptional
integer

Seed for image generation.

Default: -1Range: -1 - 999999999999999
stop_on_empty_maskoptional
boolean

Refers to stop the execution on an empty mask.

Default: false
thresholdoptional
number

Detection threshold

Default: 0.2Range: 0 - 1

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/automatic-mask-generator

    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.
