API Endpoint

POSThttps://api.segmind.com/v1/bria-gen-fill

Parameters

imagerequired
string | string

Provide the source image via URL or Base64. Use different formats to test input handling.

Default: "https://segmind-resources.s3.amazonaws.com/input/84380902-5a75-4ae6-b499-4e8c08777792-6e2fc83c-b77b-4f89-869e-76fdbf746c81.jpeg"
Exactly one of:
Option 1optional
string (uri)
Option 2optional
string
maskrequired
string (uri)

Define the generation area with a mask. Test different regions by altering mask shape.

Default: null
promptrequired
string

Enter a prompt to guide object generation. Try creative or detailed prompts for varied outputs.

Default: "Place a wooden bench on the grass"
mask_typeoptional
string

Specify if the mask is manual or automatic. Use 'manual' for custom, 'automatic' for algorithm-generated.

Default: "manual"
Allowed values :
"manual""automatic"
negative_promptoptional
string

Exclude elements from generation using this field. Use for undesired features or details.

Default: "No skyscrapers or ground vehicles"
preserve_alphaoptional
boolean

Decide if the alpha channel is retained. Keep true for transparency needs.

Default: true
prompt_content_moderationoptional
boolean

Moderate the prompt for safety. Enable for sensitive environments.

Default: true
seedoptional
integer

Select a seed for reproducibility. Use fixed seed for consistent results.

Default: 42
visual_input_content_moderationoptional
boolean

Enable to check input images for inappropriate content. Useful for platform compliance.

Default: false
visual_output_content_moderationoptional
boolean

Check output images for content issues. Activate for moderated environments.

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-gen-fill

    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.
