# ID-V2V API

> Mijenja stil videa prema preoblikovanom prvom kadru uz zadržavanje identiteta subjekta i kretanja

Ponovno generira izvorni video (`video_url`) u izgledu preoblikovanog prvog kadra (`image_url`), vođenog pomoću `prompt`. Do 5 `keyframes` može učvrstiti identitet u duljim isječcima. Izlaz je 480p ili 720p s `num_frames` od 17 do 241, a `segmentation_prompt` (zadano person) odabire subjekt čiji pikseli usmjeravaju rezultat.

- 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/hr/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 |  |  | Prompt koji određuje željeni stilizirani videozapis. |
| `video_url` | `video` | string (video URL) | yes |  |  | Referenca pokreta i kadriranja za generiranje, navedena kao URL izvornog videozapisa. |
| `image_url` | `image` | string (image URL) | yes |  |  | Referenca identiteta i stila za ponovno generiranje videozapisa, navedena kao URL koji upućuje na stiliziranu prvu sličicu. |
| `keyframes` |  | array of object {image_url, frame_index} | no |  | ≤ 5 items | Neobavezne sidrene točke identiteta za duge videozapise: navedite stilizirane ključne sličice s indeksima izlaznih sličica na kojima se moraju pojaviti. |
| `keyframes[].image_url` |  | string (image URL) | yes |  |  | URL stilizirane slike za sidrenu točku identiteta u dugom videozapisu; omjer slike ne smije se razlikovati od izlaznog za više od 0.1. Slika se pojavljuje bez izmjena na `frame_index`. |
| `keyframes[].frame_index` |  | integer | yes |  | ≥ 1 | Postavite ključnu sličicu na izlazni položaj od najmanje 1 i manji od ukupnog broja izlaznih sličica, koristeći indeksiranje od 0. Položaj 0 rezerviran je za stiliziranu početnu sličicu iz `image_url`. |
| `resolution` |  | enum (string) | no | `720p` | `480p`, `720p` | Odaberite 720p za izlaz 1280×720 ili 720×1280, odnosno 480p za izlaz 832×480 ili 480×832. Orijentacija izvornog videozapisa određuje koje se dimenzije primjenjuju. |
| `num_frames` |  | integer | no | `81` | 17 – 241 | Ograničite broj sličica koje treba proizvesti; ako izvor sadrži manje sličica, njihov broj postaje gornja granica. |
| `segmentation_prompt` |  | string | no | `person` | ≤ 100 characters | Prompt za odabir subjekta za SAM-3 koji određuje područje čiji će pikseli usmjeravati generiranje. Izvan tog segmentiranog subjekta generiranje nije ograničeno. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | Kontrola kvalitete i brzine isječka izražena kao broj koraka uzorkovanja difuzije za svaki isječak: veći broj koraka poboljšava kvalitetu, ali traje dulje. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Snaga vođenja bez klasifikatora koja usklađuje pridržavanje prompta i kreativnost. |
| `vace_scale` |  | number | no | `1` | 0 – 2 | Pridržavanje strukture izvornog videozapisa, prilagođeno skalom uvjetovanja VACE. |
| `seed` |  | integer \| null | no |  |  | Nasumična početna vrijednost zajednička svim isječcima pri generiranju više isječaka, koja omogućuje ponovljivo generiranje. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Omogućuje sigurnosne provjere ulaza i izlaza. |

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:

  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",

## 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",
    "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/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.
