# Sam 3 · 3D Objects API

> Hujenga vitu vya 3D kutoka kwenye picha, vilivyochaguliwa kwa vidokezo au maski za maandishi, pointi au visanduku, pamoja na matokeo ya splat

Hubadilisha vitu kwenye picha kuwa mali za 3D. Chagua vitu kwa `mask_urls`, `prompt` ya maandishi, `point_prompts` au `box_prompts`; visanduku vingi hutoa vitu tofauti. `detection_threshold` inakubali 0.1 hadi 1, na `export_textured_glb` huunganisha tekstura na UV. Hutoa GLB, faili za Gaussian splat, faili kwa kila kitu katika mandhari yenye vitu vingi, metadata na kifurushi cha 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/sw/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 ya picha kwa uundaji upya wa 3D. |
| `mask_urls` |  | array of image URL | no |  |  | Orodha ya hiari ya URL za maski kwa kila kitu. Bila maski, segmentation ya kiotomatiki hutumia kidokezo, point_prompts au box_prompts zikipeanwa; ikiwa maski wala vidokezo vya segmentation havijatolewa, picha nzima hutumiwa. |
| `prompt` |  | string \| null | no | `car` |  | Maandishi yanayotumika kwa segmentation ya kiotomatiki ikiwa maski hazipo, kama vile 'chair' au 'lamp'. |
| `point_prompts` |  | array of object {x, y, label, object_id} | no | `[]` |  | Vidokezo vinavyotegemea nukta vinavyotumika kwa segmentation ya kiotomatiki ikiwa maski hazipo. |
| `point_prompts[].x` |  | integer \| null | no |  |  | Nafasi ya kidokezo kwenye mhimili wa X. |
| `point_prompts[].y` |  | integer \| null | no |  |  | Nafasi ya kidokezo kwenye mhimili wa Y. |
| `point_prompts[].label` |  | enum (integer) \| null | no |  | `0`, `1` | Lebo ya mandhari ya mbele/mandharinyuma: 1 huonyesha mandhari ya mbele; 0 huonyesha mandharinyuma. |
| `point_prompts[].object_id` |  | integer \| null | no |  |  | Kitambulisho cha hiari kinachopanga vidokezo vinavyoboresha kitu kimoja. Ikiwa maandishi pia yametolewa kama kidokezo, kitambulisho hiki huamua ni kitu gani kilichogunduliwa ambacho pointi hizo huboresha. |
| `box_prompts` |  | array of object {x_min, y_min, x_max, y_max, object_id} | no | `[]` |  | Vidokezo vya visanduku vinavyotoa maski za vitu binafsi kwa uundaji upya wa 3D kupitia segmentation ya kiotomatiki, vinavyotumika tu maski zisipotolewa. Visanduku vingi vinaweza kutumwa. |
| `box_prompts[].x_min` |  | integer \| null | no |  |  | Koordinati ya chini ya x ya kisanduku. |
| `box_prompts[].y_min` |  | integer \| null | no |  |  | Koordinati ya chini ya y ya kisanduku. |
| `box_prompts[].x_max` |  | integer \| null | no |  |  | Kiwianishi cha juu zaidi cha X cha kisanduku. |
| `box_prompts[].y_max` |  | integer \| null | no |  |  | Kiwianishi cha juu zaidi cha Y cha kisanduku. |
| `box_prompts[].object_id` |  | integer \| null | no |  |  | Kitambulisho cha hiari kinachopanga visanduku vinavyoboresha kitu kimoja. |
| `seed` |  | integer \| null | no |  |  | Seed inayotumika kwa uzalishaji wa nasibu unaoweza kurudiwa. |
| `pointmap_url` |  | string \| null | no |  |  | URL ya hiari ya kuboresha ukadiriaji wa kina katika uundaji upya wa 3D kwa kutoa pointmap au data ya kina ya nje kama NPY au NPZ. |
| `detection_threshold` |  | number \| null | no |  | 0.1 – 1 | Kikomo cha kujiamini cha utambuzi, kinachoachwa kwenye thamani chaguomsingi ya modeli kisipotolewa. Thamani ziko kati ya 0.1 na 1.0, huku thamani ndogo zikibadilisha usahihi kwa kuongeza idadi ya utambuzi. |
| `export_textured_glb` |  | boolean | no | `false` |  | Chaguo la usafirishaji wa GLB: kuwezesha chaguo hili hubadilisha rangi za vertex kuwa texture iliyookwa na 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.
