# Image Outpaint API

> Pinapalawak ang larawan palabas nang hanggang 700 px bawat gilid, na may opsyonal na zoom-out at teksto prompt para gabayan ang mga bagong bahagi

Pinapalawak ang source na larawan mula sa `image_url` sa pamamagitan ng pagtatakda ng `expand_left`, `expand_right`, `expand_top` at `expand_bottom`, na bawat isa ay 0 hanggang 700 pixels. Ang mga idinagdag na margin lang ang pinupunan. Pinaliliit muna ng `zoom_out_percentage` (0 hanggang 90, default 20) ang orihinal sa loob ng frame, at ginagabayan ng opsyonal na `prompt` na hanggang 500 character ang bagong content. Nagbabalik ito ng 1 hanggang 4 na larawan sa png, jpeg, jpg o webp.

- Made by: Utility
- Category: Image Editing
- Output: image
- Estimated price per run: $0.07 / image (cheapest run $0.07 (70 API credits))
- Run: `POST https://api.doitong.com/v1/run/image-apps-v2/outpaint`
- Quote: `POST https://api.doitong.com/v1/quote/image-apps-v2/outpaint`
- Docs page: https://doitong.com/fil/developers/models/image-apps-v2/outpaint

## Pricing

Price: **$0.07 / image**. Estimated from the typical cost of one run, per output (`num_images`). The quote is exactly what the run charges.

The full example input below costs $0.07 = 70 API credits (1 image × 70 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/image-apps-v2/outpaint` 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 ng larawang ie-extend sa pamamagitan ng outpainting. |
| `expand_left` |  | integer | no | `0` | 0 – 700 | Expansion sa kaliwang bahagi sa pixels, na pupunuin ng itim; tumatanggap ng 0–700. |
| `expand_right` |  | integer | no | `0` | 0 – 700 | Expansion sa kanang bahagi sa pixels, na pupunuin ng itim; tumatanggap ng 0–700. |
| `expand_top` |  | integer | no | `0` | 0 – 700 | Expansion sa itaas na gilid sa pixels, na pupunuin ng itim; tumatanggap ng 0–700. |
| `expand_bottom` |  | integer | no | `0` | 0 – 700 | Expansion sa ibabang gilid sa pixels, na pupunuin ng itim; tumatanggap ng 0–700. |
| `zoom_out_percentage` |  | number | no | `20` | 0 – 90 | Porsyento ng zoom-out na inilalapat sa loob ng canvas na hindi nagbabago: iniiwan ng 50 ang larawan sa 50% ng orihinal nitong laki, na napalilibutan ng itim. Kapag ibinigay, pinapaliit ng setting na ito ang larawan ayon sa tinukoy na porsyento at pinupuno ng itim na margin ang napalaya nitong espasyo. |
| `prompt` |  | string | no | `` | ≤ 500 characters | Opsyonal na outpainting guidance na idinadagdag pagkatapos ng base outpaint instruction, halimbawa: 'with a beautiful sunset in the background'. |
| `seed` |  | integer \| null | no |  |  | Seed para sa nauulit na mga larawan: ang magkaparehong prompt at seed ay gumagawa ng magkaparehong larawan kapag hindi nagbago ang bersyon ng modelo. |
| `num_images` | `num_outputs` | integer | no | `1` | 1 – 4 | Bilang ng larawang bubuuin. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Pag-activate ng safety checker; pinapagana ng true ang checking. |
| `output_format` |  | enum (string) | no | `png` | `png`, `jpeg`, `jpg`, `webp` | File format ng resultang larawan. |

File parameters (`image`) 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/image-apps-v2/outpaint?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/image-apps-v2/outpaint?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/image-apps-v2/outpaint", 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": "image-apps-v2/outpaint",
      "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.
