API Endpoint

POSThttps://api.segmind.com/v1/bria-expand-image

Parameters

imagerequired
string (uri)

Input image for processing. Use an accessible URL or Base64 string.

Default: "https://segmind-resources.s3.amazonaws.com/input/3f05def3-776b-4944-a0f6-c23cec41a09e-cbf61f2b859662c0.jpg"
aspect_ratiooptional
string

Defines image aspect ratio. For landscapes use 16:9, for portraits use 2:3.

Default: "4:3"
Allowed values :
"1:1""2:3""3:2""3:4""4:3""4:5""5:4""9:16""16:9"
negative_promptoptional
string

Excludes elements in generating image. Use 'cityscapes' to avoid urban features.

Default: "Do not include buildings or modern architecture"
preserve_alphaoptional
boolean

Keeps transparency in images. Use with PNGs to maintain transparency.

Default: true
promptoptional
string

Text guidance for image expansion. Use keywords like 'sunset' or 'ocean'.

Default: null
prompt_content_moderationoptional
boolean

Scans prompt for NSFW content. Keep enabled for safe usage.

Default: true
seedoptional
integer

Sets randomization seed for reproducibility. Use any integer for consistency.

Default: 12345
visual_input_content_moderationoptional
boolean

Moderates input visuals for NSFW content. Enable for safer uploads.

Default: false
visual_output_content_moderationoptional
boolean

Moderates output visuals for NSFW content. Use to ensure clean results.

Default: false

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/bria-expand-image

    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.
