https://api.segmind.com/v1/qwen-imageParameters
promptrequiredstringDescribe imaginative landscapes or detailed environments for image generation. Examples: 'A mystical dragon cave' or 'rustic mountain cabin'.
stepsrequiredintegerNumber of steps for generating the image
30Range: 1 - 50aspect_ratiooptionalstringDefines image proportion. Use 16:9 for cinematic, 1:1 for square formats.
"16:9""1:1""16:9""9:16""4:3""3:4""3:2""2:3"base64optionalbooleanOutputs base64 image string. Enable for embedding, disable for files.
falseguidanceoptionalnumberAdjusts adherence to prompt. Set 2.5 for creativity, 5.0 for precision.
3.5Range: 1 - 20image_formatoptionalstringSelect image format. Use 'jpeg' for small files, 'png' for quality.
"png""png""jpeg""webp"negative_promptoptionalstringExclude elements to control results. Useful filters: 'blur' for clarity, 'cartoonish' for realism.
"blurry, cartoonish"qualityoptionalintegerSet clarity level. Choose 80 for web, 100 for print quality.
90Range: 10 - 100seedoptionalintegerDetermines image variation. Use -1 for unique images, fixed for repeatability.
-1Response 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/qwen-imageSubmit — 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.
