Pixal3D API - AI 3D Model Generation APIs

by Pixal3D

Pixal3D API is a cutting-edge 3D generative reconstruction interface designed to instantly transform 2D visuals into highly accurate, asset-ready 3D models. By utilizing a sophisticated pixel-aligned back-projection scheme, the API seamlessly lifts standard image features directly into a 3D spatial volume. This unique framework bridges the gap between traditional geometric reconstruction and AI generation, tightly binding visible surfaces to the source input while intelligently completing hidden elements through advanced generative priors. Engineered for effortless integration, it allows developers to automate high-fidelity, object-separated 3D mesh creation from both single-view and multi-view perspectives.

Webhook (Optional)

Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.

Webhook Headers

Header	Required	Default	Description
`X-Webhook-URL`	Yes (to enable)	—	HTTPS endpoint on your server that will receive the `POST` callback. Must respond `2xx` within a few seconds (process async if needed).
`X-Webhook-Mode`	No	`terminal`	`terminal` — fires once at the final status (`COMPLETED`/`FAILED`/`ERROR`). `sync` — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates.

Example: enable webhook

X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal

Callback Payload

Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):

{
  "request_id": "pixal3d_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "COMPLETED",
  "model_id": "pixal3d",
  "error": null,
  "output": {
    "media_url": [
      "https://pub-582b7213209642b9b995c96c95a30381.r2.dev/v1/pixal3d_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/output.glb"
    ],
    "media_type": "model/glb"
  },
  "created_at": "2026-05-22T13:17:32.110Z",
  "updated_at": "2026-05-22 13:19:23",
  "completed_at": "2026-05-22 13:19:23"
}

Failure callback shape

{
  "request_id": "pixal3d_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "ERROR",
  "model_id": "pixal3d",
  "error": "Description of the error",
  "output": null,
  "created_at": "...",
  "updated_at": "...",
  "completed_at": "..."
}

Delivery semantics

terminal mode (default) — exactly one POST when the request reaches a terminal status. No callback during PROCESSING.
sync mode — POST on every status poll (with delay capped at ~15s) plus a final POST at terminal status. Use when you want progress updates.
Idempotency — use request_id as your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates.
Response — respond 200 OK within a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries.
HTTPS required — plain http:// URLs are rejected.

Request Parameters - Pixal3D generate request

Parameter	Required	Type	Default	Allowed values / range	Description
image_url	Yes	string	—	—	URL of the input image to convert to 3D. Must be publicly accessible.
seed	No	integer	—	—	Random seed for reproducibility. If omitted, a random seed is used.
resolution	No	enum	1024	1024, 1536	Output resolution for initial structure generation. Higher values yield more detail but increase processing time.
ss_guidance_strength	No	float	7.5	—	How closely the initial 3D structure follows the input image. Higher values increase fidelity but may introduce artifacts.
ss_guidance_rescale	No	float	0.7	—	Dampens artifacts from high guidance in stage 1 (initial structure generation).
ss_sampling_steps	No	integer	12	—	Number of denoising steps for the initial 3D structure generation.
ss_rescale_t	No	float	5	—	Controls noise schedule sharpness for structure generation. Higher values emphasize early denoising stages.
shape_slat_guidance_strength	No	float	7.5	—	How closely the detailed geometry follows the input image. Higher values preserve fine structural details.
shape_slat_guidance_rescale	No	float	0.5	—	Dampens artifacts from high guidance in the shape refinement stage.
shape_slat_sampling_steps	No	integer	12	—	Number of denoising steps for shape refinement.
shape_slat_rescale_t	No	float	3	—	Controls noise schedule sharpness for shape refinement. Higher values prioritize early-stage noise reduction.
tex_slat_guidance_strength	No	float	1	—	How closely the texture follows the input image colors. Lower values prevent color oversaturation.
tex_slat_guidance_rescale	No	float	—	—	Dampens artifacts from high guidance in the texture generation stage.
tex_slat_sampling_steps	No	integer	12	—	Number of denoising steps for texture generation.
tex_slat_rescale_t	No	float	3	—	Controls noise schedule sharpness for texture generation. Higher values emphasize early denoising stages.
mesh_scale	No	float	1	—	Scale factor applied to the inferred mesh. Values >1 enlarge the model, values <1 shrink it.
max_num_tokens	No	integer	49152	—	Maximum number of high-resolution tokens used by the cascaded shape sampler. Higher values improve detail at the cost of memory and time.
decimation_target	No	integer	200000	—	Target number of vertices in the final mesh. Lower values reduce file size and improve performance.
texture_size	No	enum	2048	1024, 2048, 4096	Texture resolution baked onto the mesh. Higher values yield sharper textures but increase file size.
remesh	No	boolean	true	—	Rebuilds the mesh topology for cleaner, more uniform triangles. Disabling may preserve original topology but can result in irregular geometry.
