API Endpoint

POSThttps://api.segmind.com/v1/seededit-v3

Parameters

image_urlrequired
string (uri)

URL of the image to be edited. Use a clear source like S3 for best results.

promptrequired
string

Describe the change you want in the image. For playful edits, try 'Make the bubbles cat-shaped'.

guidance_scaleoptional
number

Provides control over prompt adherence. Use a higher value, like 9, for strict guidance.

Default: 5.5Range: 1 - 10
seedoptional
integer

Seed ensures consistent outputs. Use 42 for experiments or 1987 for varied results.

Default: 42Range: 1 - 999999
sizeoptional
string

Specifies output size behavior. Choose 'square' for social media or 'original' for no cropping.

Default: "adaptive"
Allowed values :
"adaptive""original""square"

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/seededit-v3

    Submitreturns request_id, status_url, response_url

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

  3. 3

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.
