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

Code Examples

Ready-to-run snippets

const apiKey = process.env.SANDBASE_API_KEY;
const response = await fetch("https://api.sandbase.ai/v1/run", {
  method: "POST",
  headers: {
    Authorization: `Bearer ${apiKey}`,
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
    "model": "meta/sam-3/3d-body",
    "image": "https://static.sandbase.ai/examples/meta/sam-3/3d-body/input_image_0.jpeg",
    "export_meshes": true,
    "include_mhr_params": true,
    "include_3d_keypoints": true
  }),
});

if (!response.ok) throw new Error(await response.text());
let result = await response.json();
for (let attempt = 0; attempt < 120 && !["completed", "failed", "timeout"].includes(result.status); attempt++) {
  await new Promise((resolve) => setTimeout(resolve, 2_000));
  const poll = await fetch(`https://api.sandbase.ai/v1/run/${result.id}`, {
    headers: { Authorization: `Bearer ${apiKey}` },
  });
  if (!poll.ok) throw new Error(await poll.text());
  result = await poll.json();
}
if (result.status !== "completed") throw new Error(`Generation ended: ${result.status}`);
console.log(result);
