# Getting Started

> How to start using Gizmo — browser editor and API access

## Browser Editor

Gizmo runs entirely in the browser — no installation required.

1. Sign up at [gizmo.antimlabs.com](https://gizmo.antimlabs.com)
2. Sign in and open the editor
3. Type a prompt or attach a reference image
4. Watch the agent build your scene in real time

Your scenes, assets, generated textures, and exports are all stored in your Gizmo workspace.

## API Access

For programmatic workflows, Gizmo provides a REST API at `https://api.gizmo.antimlabs.com/v1/`.

1. Create an API key in [**Settings → API Keys**](https://gizmo.antimlabs.com/settings#api-keys)
2. Pass it via the `Authorization` header:

```bash theme={null}
curl "https://api.gizmo.antimlabs.com/v1/whoami" \
  -H "Authorization: Bearer gzm_k1_YOUR_KEY"
```

See [API Access](/api-access) for the full endpoint reference.

## What Gets Generated

Every asset the agent produces includes:

* **Geometry** — parametric primitives or precision CAD solids
* **Materials** — PBR textures with surface type classification
* **Joints** — revolute, prismatic, spherical, or fixed, with axis and limits
* **Physics** — mass, inertia, friction, restitution, collision shapes
* **Affordances** — labeled handles, knobs, drawers, doors, wheels
* **Groups** — components grouped by mechanical function

## Credits and Billing

Generation consumes credits. Your current balance is visible in Settings. The API returns `402 Insufficient Credits` when your balance is depleted.
