https://api.segmind.com/v1/gpt-image-2Parameters
promptrequiredstringText describing the image; supports in-image typography across scripts. Lead with subject, style, lighting.
backgroundoptionalstring'opaque' for full scenes; 'transparent' for logos, stickers, and product cutouts.
"opaque""opaque"heightoptionalintegerOptional custom height in pixels. Set both Width and Height to override the Size preset. Rules: each a multiple of 16, aspect ratio between 1:3 and 3:1, longest edge <= 3840, total pixels 655,360-8,294,400.
nullimage_urlsoptionalstring[]A list of reference images. Include one or more URLs to edit or draw context from.
mask_image_urloptionalstring (uri)Optional mask image URL for surgical inpainting. White regions of the mask indicate areas to edit; everything outside stays pixel-perfect.
""moderationoptionalstringContent filter strictness; 'auto' is the safe default. Use 'low' only for permitted use cases.
"auto""low""auto"output_compressionoptionalintegerCompression level 0-100; 100 preserves text crispness. Lower values reduce file size.
100output_formatoptionalstringUse 'png' for crisp text, 'webp' for size, 'jpeg' for broad compatibility.
"png""png""jpeg""webp"qualityoptionalstringRendering fidelity; 'high' keeps typography crisp. Use 'medium' or 'low' only for previews.
"high""low""medium""high""auto"sizeoptionalstringOutput resolution (WIDTHxHEIGHT). 'auto' lets the model pick. For a custom resolution not listed, set Width and Height instead. Constraints: each edge a multiple of 16, aspect ratio 1:3-3:1, longest edge <= 3840, total pixels 655,360-8,294,400.

Set both Width and Height to override the Size preset. Rules: each a multiple of 16, aspect ratio between 1:3 and 3:1, longest edge <= 3840, total pixels 655,360-8,294,400.
nullResponse Type
Returns: Text/JSON
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
POST /v2/gpt-image-2Submit — returns request_id, status_url, response_url
- 2
GET /v2/requests/{id}/statusPoll — until COMPLETED or FAILED
- 3
GET /v2/requests/{id}Result — final response body
Status states
- 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.
