https://api.segmind.com/v1/ssd-1bParameters
promptrequiredstringDescriptive phrases guide the model's output. Include vivid details and context for diverse results.
base64optionalbooleanEncodes images in Base64 for seamless integration. Enable if encoding is needed.
falseguidance_scaleoptionalnumberDetermines output fidelity to prompt. Higher for precision, lower for creative variance.
7Range: 1 - 25img_heightoptionalintegerDetermines output height; fixed at 1024 for optimal resolution.
10241024img_widthoptionalintegerDefines output width; set to 1024 for best clarity and detail.
10241024negative_promptoptionalstringFilters out unwanted elements. Use to enforce clarity and aesthetics.
"blurry,out of focus"num_inference_stepsoptionalintegerControls detail via denoising steps. Raise steps for intricate textures, lower for speed.
45Range: 20 - 100samplesoptionalintegerSpecifies the number of images to generate. More samples increase diversity, fewer for speed.
2Range: 1 - 4scheduleroptionalstringDetermines denoising pattern. 'DPM Multi' for balanced outputs, 'Euler' for sharper results.
"DPM Multi""DDIM""DPM Multi""DPM Single""Euler a""Euler""Heun""DPM2 a Karras""DPM2 Karras""LMS""PNDM"+2 moreseedoptionalintegerEnsures repeatable results by fixing randomness. User-defined or random for unique images.

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/ssd-1bSubmit — 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.
Common Error Codes
The API returns standard HTTP status codes. Detailed error messages are provided in the response body.
