https://api.segmind.com/v1/hunyuan-3d-3.1-pro-image-to-3dParameters
input_image_urlrequiredstring (uri)Front view of a single object. JPG, PNG or WEBP, 128-5000 px, up to 8 MB. Works best on a plain background with the object filling over half the frame.
back_image_urloptionalstring (uri)Back/rear view of the object. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
bottom_image_urloptionalstring (uri)Bottom view. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
enable_pbroptionalbooleanGenerate PBR materials (metallic, roughness, normal maps). Adds a surcharge. Ignored, and not charged, when Generate type is Geometry.
falseface_countoptionalintegerTarget polygon count, 40,000 to 1,500,000. Any value other than the 500,000 default adds a surcharge.
500000Range: 40000 - 1500000generate_typeoptionalstringNormal returns a textured model. Geometry returns an untextured white mesh.
"Normal""Normal""Geometry"left_front_image_urloptionalstring (uri)Left-front view at 45 degrees. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
left_image_urloptionalstring (uri)Left side view. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
right_front_image_urloptionalstring (uri)Right-front view at 45 degrees. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
right_image_urloptionalstring (uri)Right side view. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
top_image_urloptionalstring (uri)Top-down view. Optional. Adding any extra view adds a multi-view surcharge (flat, not per image).
Response Type
Returns: 3D Model
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/hunyuan-3d-3.1-pro-image-to-3dSubmit — 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.
