# ID-V2V API

> Endurmótar myndband út frá endurmótuðum fyrsta ramma og heldur auðkenni og hreyfingu viðfangsefnisins

Myndar upprunamyndband (`video_url`) að nýju í útliti endurmótaðs fyrsta ramma (`image_url`), stýrt af `prompt`. Allt að 5 `keyframes` geta fest auðkennið í lengri myndböndum. Úttak er 480p eða 720p með `num_frames` frá 17 til 241 og `segmentation_prompt` (sjálfgefið person) velur viðfangsefnið sem hefur áhrif á niðurstöðuna.

- Model id: `id-v2v`
- Made by: Open model
- Category: Video to Video
- Output: video
- Price per second of your output video: $0.20 / second of output video (cheapest run $0.20 (200 API credits))
- Run: `POST https://api.doitong.com/v1/run/id-v2v`
- Quote: `POST https://api.doitong.com/v1/quote/id-v2v`
- Docs page: https://doitong.com/is/developers/models/id-v2v

## Pricing

Price: **$0.20 / second of output video**. Price per second of your output video: 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 $1.013 = 1013 API credits (5.0625 s output video × $0.20).

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/id-v2v` 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 |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | Kvaðning sem tilgreinir æskilegt endurstílað myndband. |
| `video_url` | `video` | string (video URL) | yes |  |  | Tilvísun í hreyfingu og ramma fyrir efnisgerð, gefin sem vefslóð upprunamyndbandsins. |
| `image_url` | `image` | string (image URL) | yes |  |  | Tilvísun í auðkenni og stíl fyrir endurgerð myndbands, gefin sem vefslóð sem vísar á endurstílaða fyrsta rammann. |
| `keyframes` |  | array of object {image_url, frame_index} | no |  | ≤ 5 items | Valfrjálsar auðkennisfestur fyrir löng myndbönd: gefðu upp endurstílaða lykilramma ásamt úttaksrammavísunum þar sem þeir eiga að birtast. |
| `keyframes[].image_url` |  | string (image URL) | yes |  |  | Vefslóð endurstílaðrar myndar fyrir auðkennisfestu í löngu myndbandi; myndhlutfall myndarinnar má ekki vera meira en 0.1 frá úttakinu. Myndin birtist óbreytt á `frame_index`. |
| `keyframes[].frame_index` |  | integer | yes |  | ≥ 1 | Settu lykilrammann á úttaksstað sem er að minnsta kosti 1 og undir heildarfjölda úttaksramma, með 0-grundaðri vísitölu. Staður 0 er frátekinn fyrir endurstílaða upphafsrammann úr `image_url`. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Veldu 720p fyrir 1280×720 eða 720×1280 úttak, eða 480p fyrir 832×480 eða 480×832 úttak. Stefna upprunamyndbandsins ákvarðar hvaða mál eru notuð. |
| `num_frames` |  | integer | no | `81` | 17 – 241 | Takmarkaðu hversu marga ramma á að búa til; ef uppsprettan inniheldur færri ramma verður fjöldi þeirra efri mörkin. |
| `segmentation_prompt` |  | string | no | `person` | ≤ 100 characters | Kvaðning fyrir val á myndefni í SAM-3 sem auðkennir svæðið þar sem pixlarnir leiðbeina efnisgerð. Fyrir utan það afmarkaða myndefni er efnisgerðin óheft. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | Stýring á gæðum og hraða myndskeiðs, gefin sem fjöldi dreifisýnatökuskrefa fyrir hvert myndskeið: fleiri skref bæta gæði en taka lengri tíma. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Styrkur leiðsagnar án flokkara sem vegur saman fylgni við kvaðningu og sköpunargáfu. |
| `vace_scale` |  | number | no | `1` | 0 – 2 | Fylgni við byggingu upprunamyndbandsins, stillt með VACE-skilyrðiskvarðanum. |
| `seed` |  | integer \| null | no |  |  | Slembifræ sem deilt er milli allra myndskeiða þegar mörg myndskeið eru búin til, sem gerir endurtekna efnisgerð mögulega. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Virkjar öryggisathuganir á bæði inntaki og úttaki. |

File parameters (`video`, `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:

## 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/id-v2v?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
    "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

### Python

```python
import os
import requests

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

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

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/id-v2v", 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":

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": "id-v2v",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
        "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.
