# Object Upload

Create an object tracking target by posting object metadata and uploading the 3D model to the returned presigned URL.

To create a new Object for tracking using the upload API, make a POST request to **/v1/vps/object** with your authentication token, providing the object name, tracking type (full for 360-degree tracking or side for side-view only), and source details including the file type (glb), provider (web), and coordinate system (RHS for right-handed or LHS for left-handed).

The API will respond with a pre-signed S3 upload URL, unique object ID, and object code.

{% hint style="info" %}
**Objects are now uploaded as a `.zip`.** Package your `.glb` mesh into a zip archive and `PUT` it to the returned `uploadUrl` with **`Content-Type: application/zip`**. Once uploaded, the system automatically unpacks the archive and processes the model for Object tracking. (The `source.fileType` in your request stays `glb`. Only the upload container is a zip.)
{% endhint %}

Once uploaded, the system will automatically process the model for Object tracking.

# Agent Instructions

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.multiset.ai/fundamentals/rest-api-docs/modelset-upload.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
