# Sam 3 · 3D Objects API

> Jirrekkonstruċi oġġetti 3D minn immaġni, magħżula permezz ta’ prompts ta’ test, punt jew kaxxa jew maskri, b’output splat

Jikkonverti l-oġġetti f’ritratt f’assi 3D. Agħżel l-oġġetti b’`mask_urls`, prompt ta’ test `prompt`, `point_prompts` jew `box_prompts`; diversi kaxxi jagħtu oġġetti separati. `detection_threshold` jaċċetta 0.1 sa 1, u `export_textured_glb` jintegra n-nisġa u l-UVs. L-outputs huma GLB, fajls Gaussian splat, fajls għal kull oġġett f’xeni b’diversi oġġetti, metadata u pakkett zip.

- Model id: `sam-3/3d-objects`
- Made by: Meta
- Category: Image to 3D
- Output: 3d
- Estimated price per run: $0.02 / run (cheapest run $0.02 (20 API credits))
- Run: `POST https://api.doitong.com/v1/run/sam-3/3d-objects`
- Quote: `POST https://api.doitong.com/v1/quote/sam-3/3d-objects`
- Docs page: https://doitong.com/mt/developers/models/sam-3/3d-objects

## Pricing

Price: **$0.02 / run**. Estimated from the typical cost of one run. The quote is exactly what the run charges.

The full example input below costs $0.02 = 20 API credits (1 request × 20 API credits).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/sam-3/3d-objects` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `image_url` | `image` | string (image URL) | yes |  |  | URL tal-immaġni għar-rikostruzzjoni 3D. |
| `mask_urls` |  | array of image URL | no |  |  | Lista fakultattiva ta' URLs tal-maskri għal kull oġġett. Mingħajr maskri, is-segmentazzjoni awtomatika tuża prompt, point_prompts jew box_prompts jekk jiġu pprovduti; jekk ma jingħatawx la maskri u lanqas prompts tas-segmentazzjoni, tintuża l-immaġni kollha. |
| `prompt` |  | string \| null | no | `car` |  | Test użat għas-segmentazzjoni awtomatika meta ma jkunx hemm maskri, bħal 'chair' jew 'lamp'. |
| `point_prompts` |  | array of object {x, y, label, object_id} | no | `[]` |  | Prompts ibbażati fuq punti użati għas-segmentazzjoni awtomatika meta ma jkunx hemm maskri. |
| `point_prompts[].x` |  | integer \| null | no |  |  | Pożizzjoni tal-prompt fuq l-assi X. |
| `point_prompts[].y` |  | integer \| null | no |  |  | Pożizzjoni tal-prompt fuq l-assi Y. |
| `point_prompts[].label` |  | enum (integer) \| null | no |  | `0`, `1` | Tikketta tat-tagħrif ta’ quddiem/l-isfond: 1 tindika t-tagħrif ta’ quddiem; 0 tindika l-isfond. |
| `point_prompts[].object_id` |  | integer \| null | no |  |  | Identifikatur mhux obbligatorju li jiġbor prompts li jirfinaw oġġett wieħed. Jekk test jiġi pprovdut ukoll bħala prompt, dan l-identifikatur jiddetermina liema oġġett misjub jirfinaw dawk il-punti. |
| `box_prompts` |  | array of object {x_min, y_min, x_max, y_max, object_id} | no | `[]` |  | Prompts tal-kaxxi li jipproduċu maskri individwali tal-oġġetti għar-rikostruzzjoni 3D permezz tas-segmentazzjoni awtomatika, użati biss meta ma jiġux ipprovduti maskri. Jistgħu jintbagħtu diversi kaxxi. |
| `box_prompts[].x_min` |  | integer \| null | no |  |  | Il-koordinata x minima għall-kaxxa. |
| `box_prompts[].y_min` |  | integer \| null | no |  |  | Il-koordinata y minima għall-kaxxa. |
| `box_prompts[].x_max` |  | integer \| null | no |  |  | Koordinata X massima għall-kaxxa. |
| `box_prompts[].y_max` |  | integer \| null | no |  |  | Koordinata Y massima għall-kaxxa. |
| `box_prompts[].object_id` |  | integer \| null | no |  |  | Identifikatur mhux obbligatorju li jiġbor kaxxi li jirfinaw oġġett wieħed. |
| `seed` |  | integer \| null | no |  |  | Seed użat għall-ġenerazzjoni każwali riproduċibbli. |
| `pointmap_url` |  | string \| null | no |  |  | URL fakultattiv għat-titjib tal-istima tal-fond fir-rikostruzzjoni 3D billi jipprovdi dejta esterna ta' pointmap jew fond bħala NPY jew NPZ. |
| `detection_threshold` |  | number \| null | no |  | 0.1 – 1 | Limitu ta' qtugħ tal-kunfidenza tad-detezzjoni, li jitħalla fuq il-prestabbilit tal-mudell jekk jitħalla barra. Il-valuri jvarjaw minn 0.1 sa 1.0; valuri iżgħar jnaqqsu l-preċiżjoni iżda jżidu n-numru ta' detezzjonijiet. |
| `export_textured_glb` |  | boolean | no | `false` |  | Għażla tal-esportazzjoni GLB: l-attivazzjoni tissostitwixxi l-kuluri tal-vertiċi b'tessut maħruq u UVs. |

File parameters (`image`, `mask_urls`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "image": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

A fuller example:

```json
{
  "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/sam-3/3d-objects?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/sam-3/3d-objects?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/sam-3/3d-objects", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "sam-3/3d-objects",
      "input": {
        "image_url": "https://content.doitong.com/images/showcase/v3/gen_fox_cartoon.jpg"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
