# Void Video Inpainting API

> Poistaa videosta kohteen ja sen vaikutukset kohtaukseen maskivideon tai tekstimuotoisen maskikehotteen avulla

Vastaanottaa `video_url`-videon ja halutun taustan kuvaavan `prompt`-kehotteen. Anna `quad_mask_video_url` tai anna `mask_prompt`, jotta maski luodaan. Säätöihin kuuluvat `num_frames` (1–197), `num_inference_steps` (1–50), `guidance_scale`, `strength` ja valinnainen hitaampi `enable_pass2_refinement` ajallista yhdenmukaisuutta varten.

- Run: `POST https://api.doitong.com/v1/run/void-video-inpainting`

## Pricing

Price: **from $0.10 / run** (the lowest tier; the quote prices your exact input). Price per run: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $0.10 = 100 API credits (1 run × $0.10).

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/void-video-inpainting` 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 |
|---|---|---|---|---|---|---|
| `video_url` | `video` | string (video URL) | yes |  |  | Lähdevideon URL, joka sisältää poistettavaksi tarkoitetun kohteen. |
| `quad_mask_video_url` |  | string (video URL) | no | `` |  | Poistomaskin video-URL; jos sitä ei toimiteta, sovellus luo väliaikaisen videomaskin SAM-3-videopäätepisteen kautta käyttäen `mask_prompt`-arvoa ja muuntaa sen sitten automaattisesti quadmaskiksi. Parhaat tulokset saat toimittamalla VOID-tyylisen quadmaskin, jossa käytetään 4 harmaasävyarvoa: 255 säilytettävälle taustalle, 127 vaikutusalueelle, 63 limitykselle ja 0 poistettavalle kohteelle. Myös binaariset maskit hyväksytään: 255 säilyttää ja 0 poistaa. |
| `mask_prompt` |  | string \| null | no |  |  | SAM-3:n maskikohdetta koskevat ohjeet väliaikaisen maskivideon luomiseen, kun `quad_mask_video_url`-arvoa ei toimiteta. Määritä maskattava kohde, esimerkiksi lähdevideosta poistettava esine tai henkilö. |
| `prompt` |  | string | yes |  |  | Kuvaus siitä, miltä taustan tulee näyttää kohteen poistamisen jälkeen. |
| `enable_pass2_refinement` |  | boolean | no | `false` |  | Valinnainen VOID-hienosäätö, joka vaihtaa hitaamman käsittelyn mahdollisesti parempaan ajalliseen yhtenäisyyteen pidemmissä leikkeissä. Se käyttää vääristetyn kohinan hienosäätöä vaiheena Pass 2 vaiheen Pass 1 jälkeen. |
| `negative_prompt` |  | string | no | `The video is not of a high quality, it has a low resolution. Watermark present in each frame. The background is solid. Strange body and strange trajectory. Distortion.` |  | Negatiivinen kehote, joka kuvaa ei-toivottuja tuloksia ja ohjaa generointia niistä poispäin. |
| `num_inference_steps` |  | integer | no | `30` | 1 – 50 | Kohinanpoistovaiheiden määrä. Sen kasvattaminen parantaa laatua mutta lisää viivettä. |
| `guidance_scale` |  | number | no | `1` | 0 – 20 | Luokittelijavapaan ohjauksen voimakkuus. |
| `strength` |  | number | no | `1` | 0 – 1 | Kohinanpoiston voimakkuus; 1.0 tarkoittaa täydellistä kohinanpoistoa. |
| `seed` |  | integer \| null | no |  |  | Toistettavia tuloksia ohjaava satunnaisuussiemen. |
| `num_frames` |  | integer | no | `85` | 1 – 197 | Pyydetty ajallinen päättelyikkuna, jonka taustajärjestelmä säätää yhteen CogVideoX:n turvallisista kooista 69, 77, 85, ..., 197. Lähin tällainen koko valitaan ajallisen pakkauksen ja lohkomisen mahdollistamiseksi. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Ottaa käyttöön generoidun sisällön turvallisuustarkistukset. |

File parameters (`video`, `quad_mask_video_url`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

## 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/void-video-inpainting?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }'

# 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/void-video-inpainting?wait=20", {

  }),
});
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 = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/void-video-inpainting", 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": "void-video-inpainting",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
      },
      "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.
