Pixal3D API - AI 3D Model Generation API: Pricing, Documentation

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.

Using curl? These are HTTP request headers — pass each with -H, e.g. -H "X-Webhook-URL: https://your-server.com/webhook/callback". Do not paste them as bare lines, and end every line of a multi-line command with \.

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 a publicly accessible URL. Supported formats: JPG, PNG, WEBP.
seed	No	integer	—	—	Random seed for reproducibility. Reuse the same seed with identical settings to reproduce the same result; leave it empty for a different output each time.
resolution	No	enum	1024	`1024`, `1536`	Output resolution used for the initial structure generation. Higher values are slower but produce more detail.
ss_guidance_strength	No	float	7.5	0-10	How closely the initial 3D structure follows the input image. Higher values produce more faithful but potentially noisier results.
ss_guidance_rescale	No	float	0.7	0-1	Dampens artifacts from high guidance in stage 1 (initial structure generation). Lower values allow stronger guidance effects; higher values stabilize the output.
ss_sampling_steps	No	integer	12	1-50	Number of denoising steps for the initial structure. More steps are slower but can improve quality.
ss_rescale_t	No	float	5	1-6	Controls noise-schedule sharpness for structure generation. Higher values produce sharper transitions. Most users can leave this at the default.
shape_slat_guidance_strength	No	float	7.5	0-10	How closely the detailed geometry follows the input image. Higher values add more detail but may introduce noise.
shape_slat_guidance_rescale	No	float	0.5	0-1	Dampens artifacts from high guidance in the shape refinement stage. Increase if you see noisy geometry.
shape_slat_sampling_steps	No	integer	12	1-50	Number of denoising steps for shape refinement. More steps are slower but can produce smoother geometry.
shape_slat_rescale_t	No	float	3	1-6	Controls noise-schedule sharpness for shape refinement. Higher values produce sharper geometric detail. Most users can leave this at the default.
tex_slat_guidance_strength	No	float	1	0-10	How closely the texture follows the input image colors. Higher values produce more vivid but potentially oversaturated textures.
tex_slat_guidance_rescale	No	float	0	0-1	Dampens artifacts from high guidance in the texture generation stage. Increase if textures look noisy or show color banding.
tex_slat_sampling_steps	No	integer	12	1-50	Number of denoising steps for texture generation. More steps are slower but can produce cleaner textures.
tex_slat_rescale_t	No	float	3	1-6	Controls noise-schedule sharpness for texture generation. Higher values produce sharper texture detail. Most users can leave this at the default.
mesh_scale	No	float	1	0.1-4	Scale factor applied to the inferred mesh. Also affects the camera-distance estimation used by the model.
max_num_tokens	No	integer	49152	4096-131072	Maximum number of high-resolution tokens used by the cascaded shape sampler. Higher values allow finer geometry; lower values reduce memory use and processing time.
decimation_target	No	integer	200000	5000-1586021	Target number of vertices in the final mesh. Lower values produce smaller, simpler files but less detail.
texture_size	No	enum	2048	`1024`, `2048`, `4096`	Resolution of the texture image baked onto the mesh. Higher values capture finer surface detail but produce larger files.
remesh	No	boolean	true	`true`, `false`	Rebuilds the mesh topology for cleaner, more uniform triangles. Slower, but usually produces better results for downstream use.

Content Item Types & Limits
