# MiniMax H3 Image to Video LoRA API

> Beochan íomhá neamhbheo mar an chéad fhráma, le 1 go 3 oiriúntóir LoRA do chomhsheasmhacht an ábhair agus fráma deiridh roghnach

Tiontaíonn sé íomhá neamhbheo ina ghearrthóg físeáin le fuaim, ag úsáid oiriúntóir LoRA amháin go trí cinn chun ábhar nó stíl oilte a choinneáil comhsheasmhach. Seol `image_url` mar an fráma tosaigh agus `end_image_url` go roghnach don fhráma deiridh. Maireann an fad 5 go 15 soicind, agus is féidir `resolution` a bheith 480P, 768P, 2K nó 4K, áit a n-uas-scálaíonn 2K agus 4K bonn 768P. Is féidir gearrthóg fuaime a sholáthar trí `target_audio_url`.

## Pricing

Price: **from $0.0625 / second (5 s ≈ $0.313)** (the lowest tier; the quote prices your exact input). Billed per second of output (`duration`, default 15).

Price rules (the first rule that matches the input wins; a parameter you leave out counts as its default):

- When `resolution` = 768P: $0.075 (75 API credits) / second
- When `resolution` = 2K: $0.1625 (162.5 API credits) / second
- When `resolution` = 4K: $0.20 (200 API credits) / second

The full example input below costs $0.813 = 813 API credits (5 s × 162.5 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.ru/v1/quote/minimax/h3/image-to-video/lora` 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 |  | 1 – 50000 characters | Treoracha téacs chun an físeán a ghiniúint. |
| `duration` |  | integer | no | `5` | 5 – 15 | Fad an fhíseáin, tomhaiste i soicindí. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | Roghnaigh taifeach an fhíseáin a gineadh, agus 2K agus 4K faighte trí bhonn 768P a mhéadú. Úsáideann roghnú 480P nó 768P giniúint dhúchasach ina ionad. |
| `seed` |  | integer \| null | no |  |  | Síol don ghiniúint randamach; mura soláthraítear é, roghnaítear ceann go randamach. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Gníomhachtú an tseiceálaí sábháilteachta; cumasaíonn true an tseiceáil. |
| `prompt_expansion_mode` |  | string \| null | no | `balanced` |  | Iarracht athscríofa an leide roimh an nginiúint: roghnaigh 'quality' le haghaidh leid níos saibhre a thógann suas le thart ar 30 soicind, nó 'fast' le haghaidh toraidh i gceann thart ar soicind. Le 'balanced', déantar an rogha in aghaidh an iarratais; casann 'disabled' an leathnú as. |
| `target_audio_url` |  | string (audio URL) \| null | no |  | ≥ 1 characters | Fuaimrian roghnach athsholáthair a sholáthraítear trí URL HTTP(S) nó URI sonraí base64; caithfidh an ghearrthóg maireachtáil 2 shoicind ar a laghad agus gan a bheith níos mó ná 15 MB. Tagann an fhuaim a sholáthraítear in áit an fhuaimriain a gineadh ag luas athsheinnte gan athrú: baintear fad breise den deireadh, agus cuirtear tost le gearrthóga níos giorra chun fad an fhíseáin a mheaitseáil. D’fhéadfadh athshampláil go 96 kHz tarlú i gcás rátaí samplála atá thar a bheith ard. |
| `image_url` | `image` | string (image URL) \| null | no |  |  | URL íomhá roghnach a shainíonn an fráma tosaigh agus an chanbhás aschuir. Mura soláthraítear ach end_image_url, cinnfidh a fhráma deiridh an chanbhás ina ionad. Gan ceachtar íomhá, úsáideann an giniúint téacs-go-físeán le cóimheas gné réamhshocraithe 16:9. |
| `end_image_url` | `end_image` | string (image URL) \| null | no |  |  | URL roghnach d’íomhá an fhráma dheiridh, inúsáidte fiú gan íomhá tosaigh. Sa mhód eochrabhíoma deiridh amháin sin, cinnfidh an íomhá seo canbhás an aschuir. |
| `loras` |  | array of object {path, weight_name, scale} | yes |  | 1 – 3 items | Liosta oiriúnóirí LoRA le cur i bhfeidhm ar an trasfhoirmeoir. |
| `loras[].path` |  | string | yes |  |  | Suíomh mheáchain LoRA, tugtha mar URL nó mar aitheantas stór HuggingFace i bhfoirm owner/repo. |
| `loras[].weight_name` |  | string \| null | no |  |  | Sonraigh ainm comhaid mheáchan LoRA chun roghnú idir iliomad LoRAanna i stór HuggingFace a shainaithnítear le `path`. |
| `loras[].scale` |  | number | no | `1` | 0 – 4 | Neart tionchair LoRA, idir 0.0 agus 4.0. |

File parameters (`target_audio_url`, `image`, `end_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:

  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
  "loras": [
    {
      "path": "https://example.com/your-file.safetensors"

## 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.ru/v1/run/minimax/h3/image-to-video/lora?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",
    "loras": [
      {
        "path": "https://example.com/your-file.safetensors"
      }
    ]
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.ru/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"

```python
import os
import requests

API = "https://api.doitong.ru/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",
    "loras": [
        {
            "path": "https://example.com/your-file.safetensors",

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3/image-to-video/lora", 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()

### MCP

The MCP server at `https://api.doitong.ru/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": "minimax/h3/image-to-video/lora",
      "input": {
        "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field",
        "loras": [
          {
            "path": "https://example.com/your-file.safetensors"
          }
        ]
      },
      "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.
