https://api.segmind.com/v1/seedream-5-proParameters
promptrequiredstringText describing the image subject, style and setting. Be specific and name lighting and mood; put on-image text in quotes to render it exactly.
aspect_ratiooptionalstringWidth-to-height ratio of the output. Use 1:1 for social, 16:9 or 21:9 for banners, 9:16 for mobile, 3:4 for portraits.
"3:2""1:1""4:3""3:4""16:9""9:16""3:2""2:3""21:9"image_inputoptionalstring[]Reference image URLs for image-to-image or multi-reference editing, up to 10. Add product or character refs to preserve identity; leave empty for pure text-to-image.
output_formatoptionalstringFile format of the returned image. Use jpeg for smaller photographic files, png for transparency and lossless text or edges.
"jpeg""jpeg""png"sizeoptionalstringOutput resolution tier. Use 1K for fast drafts and iteration, 2K for print-ready detail and crisp small text.
"2K""1K""2K"watermarkoptionalbooleanToggles a visible watermark on the output. Keep false for clean production assets; set true only when attribution is required.
falseResponse 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/seedream-5-proSubmit — 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.
