# ID-V2V API

> Ath-stoidhleadh bhidio bho chiad fhrèam ath-stoidhleadh fhad ’s a chumas e dearbh-aithne agus gluasad a’ chuspair

Ath-ghinidh e bhidio tùsail (`video_url`) ann an stoidhle ciad fhrèam ath-stoidhleadh (`image_url`), air a stiùireadh le `prompt`. Faodaidh suas ri 5 `keyframes` dearbh-aithne a chumail ann an criomagan nas fhaide. Tha an toradh 480p no 720p le `num_frames` eadar 17 agus 241, agus taghaidh `segmentation_prompt` (person gu bunaiteach) an cuspair aig a bheil na piogsail a’ cumadh an toraidh.

- 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/gd/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 |

| `keyframes[].image_url` |  | string (image URL) | yes |  |  | URL ìomhaigh ath-stiallach airson acair dearbh-aithne ann am bhidio fada; chan fhaod co-mheas taobh na h-ìomhaigh a bhith nas eadar-dhealaichte na 0.1 bho cho-mheas an às-chuir. Nochdaidh an ìomhaigh gun atharrachadh aig `frame_index`. |
| `keyframes[].frame_index` |  | integer | yes |  | ≥ 1 | Cuir am prìomh-fhrèam aig suidheachadh às-chuir co-dhiù 1 agus nas ìsle na àireamh iomlan fhrèamaichean an às-chuir, a’ cleachdadh clàr-amais stèidhichte air 0. Tha suidheachadh 0 glèidhte airson a’ chiad fhrèam ath-stiallach bho `image_url`. |

| `num_frames` |  | integer | no | `81` | 17 – 241 | Cuir crìoch air an àireamh de fhrèamaichean a thèid a chruthachadh; ma tha nas lugha de fhrèamaichean anns an tùs, bidh an àireamh frèam aige mar chrìoch àrd. |
| `segmentation_prompt` |  | string | no | `person` | ≤ 100 characters | Prompt taghaidh cuspair airson SAM-3, a’ comharrachadh na roinne aig an stiùir na piogsail gineadh. Taobh a-muigh a’ chuspair sgaraichte sin, chan eil crìoch air a’ ghineadh. |
| `num_inference_steps` |  | integer | no | `30` | 2 – 40 | Smachd air càileachd is astar clip, air a chur an cèill mar àireamh cheumannan samplachaidh diffusion airson gach clip: bidh barrachd cheumannan a’ leasachadh càileachd ach bheir iad barrachd ùine. |
| `guidance_scale` |  | number | no | `5` | 1 – 10 | Neart stiùiridh classifier-free, a’ cothromachadh gèilleadh don phrompt agus cruthachalachd. |
| `vace_scale` |  | number | no | `1` | 0 – 2 | Gèilleadh structarail don bhidio tùsail, air atharrachadh tro sgèile conditioning VACE. |

## 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 '{

    "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"

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",

request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

### 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.
