Input

Image URL or upload(string)

Upload

PNG, JPEG, WebP, or GIF · 20 MiB maximum

URL of the image containing humans

This field is required.

Image URL or upload(string)

Upload

PNG, JPEG, WebP, or GIF · 20 MiB maximum

Optional URL of a binary mask image (white=person, black=background). When provided, skips auto human detection and uses this mask instead. Bbox is auto-computed from the mask.

Include Mhr Params(boolean)

Include the full MHR (Meta Human Representation) parameter set per person in the response metadata (shape, pose, expression, global rotations, joint coordinates, packed model params, raw pose). Set to `false` to return a leaner metadata block with only keypoints and camera parameters.

Export Meshes(boolean)

Export individual mesh files (.ply) per person

Include 3D Keypoints(boolean)

Include 3D keypoint markers (spheres) in the GLB mesh for visualization

Input Schema

5 parameters · 1 required · 4 optional

Parameter	Type	Required	Description
`image`	string	Required	URL of the image containing humans
`mask`	string	Optional	Optional URL of a binary mask image (white=person, black=background). When provided, skips auto human detection and uses this mask instead. Bbox is auto-computed from the mask.
`export_meshes`	boolean	Optional	Export individual mesh files (.ply) per person · Default: true
`include_mhr_params`	boolean	Optional	Include the full MHR (Meta Human Representation) parameter set per person in the response metadata (shape, pose, expression, global rotations, joint coordinates, packed model params, raw pose). Set to `false` to return a leaner metadata block with only keypoints and camera parameters. · Default: true
`include_3d_keypoints`	boolean	Optional	Include 3D keypoint markers (spheres) in the GLB mesh for visualization · Default: true

Output Schema

Field	Type	Description
`id`	string	Unique identifier for the generation task
`status`	string	Task status: pending, running, completed, failed, timeout
`model`	string	Model used for the generation
`outputs`	array	Array of output items
`outputs[].url`	string	URL of the generated artifact
`outputs[].content_type`	string	MIME type (e.g. image/png, video/mp4)
`error`	object \| null	Error details if failed, null on success
`error.type`	string	Machine-readable error type code
`error.message`	string	Human-readable error description

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

Sam 3 3D Body

Sam 3 3D Body is built for promptable segmentation and reconstruction, with this exact route focused on human-body 3D reconstruction. Sam 3 3d Body is Meta's image-to-3D AI model. Transform photographs into production-ready 3D meshes with accurate geometry and texture mapping. It is designed for production workflows that need a clearly scoped media operation instead of a generic assistant response, preserving the supplied direction while returning an artifact ready for review, iteration, or downstream assembly.

The request surface keeps creative direction and delivery choices explicit through mask_url, image_url, sync_mode, export_meshes, safety_tolerance, include_mhr_params. Teams can lock source material, describe the intended result, choose supported output controls, and rerun the same request structure across variations. This makes experiments easier to compare and larger pipelines easier to operate without hiding important decisions inside an opaque preset.

Highlights

Human-Body 3D Reconstruction. The meta/sam-3/3d-body route is dedicated to human-body 3D reconstruction, keeping inputs and outputs matched to this operation.
Precise Spatial Selection. Within meta/sam-3/3d-body, documented prompt and media controls direct precise spatial selection while keeping the brief close to the result.
Structured Masks Or Geometry. The meta/sam-3/3d-body result provides structured masks or geometry in a machine-consumable form for review and downstream production.
Route-specific control. For meta/sam-3/3d-body, documented controls include mask_url, image_url, sync_mode, export_meshes, safety_tolerance, include_mhr_params, defining the supported variation space for this exact route.

Pricing

Per request	`$0.020000`

When to Use

Scenario	Why it fits
Choose this route	When the deliverable is specifically human-body 3D reconstruction, not a neighboring generation or editing task.
Production iteration	When creative teams need repeatable precise spatial selection with an explicit request payload.
Automated pipelines	When structured masks or geometry must flow into review, storage, compositing, or publishing.
Controlled variations	When a stable brief should be rerun while changing only documented inputs.
Prototype to scale	When the same `meta/sam-3/3d-body` contract should serve a single experiment and a larger batch later.

Prompt Guide

Lead with the subject or source, then state the transformation, important spatial or temporal details, style, and finish. Supply only documented fields, keep media URLs reachable, and vary one control at a time when comparing outputs.
