# MiniMax H3 Reference to Video API

> Video no līdz 9 attēlu, 3 videoklipu un 3 audio atsaucēm, 5 līdz 15 sekundes, līdz 4K izšķirtspējai

Ģenerē video no `prompt`, kas atsauces norāda secībā, piemēram, Image 1, Video 1 vai Audio 1. Nodrošiniet līdz 9 attēliem, 3 videoklipiem un 3 audio klipiem, kopā ne vairāk kā 12 failu. `duration` ir no 5 līdz 15 sekundēm, `resolution` — 480P, 768P, 2K vai 4K, bet `aspect_ratio` ietver adaptive, 21:9, 16:9, 4:3, 1:1, 3:4 un 9:16.

- Model id: `minimax/h3/reference-to-video`
- Made by: MiniMax
- Category: Reference to Video
- Output: video
- Price per second of your output video: from $0.05 / second of output video (cheapest run $0.05 (50 API credits))
- Run: `POST https://api.doitong.ru/v1/run/minimax/h3/reference-to-video`
- Quote: `POST https://api.doitong.ru/v1/quote/minimax/h3/reference-to-video`
- Docs page: https://doitong.com/lv/developers/models/minimax/h3/reference-to-video

## Pricing

Price: **from $0.05 / second of output video** (the lowest tier; the quote prices your exact input). 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.

Price by tier:

- 480P: $0.05 / second of output video
- 768P: $0.06 / second of output video
- 2K: $0.13 / second of output video
- 4K: $0.16 / second of output video

The full example input below costs $0.65 = 650 API credits (5 s output video × $0.13 (2K)).

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/reference-to-video` 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 | Video ģenerēšanas instrukcijas ar atsaucēm, kas identificētas pēc resursa tipa un pozīcijas katrā atsauču sarakstā, izmantojot tādus apzīmējumus kā Audio 1, Video 1, Image 1, Image 2 u. c. |
| `duration` |  | integer | no | `5` | 5 – 15 | Video ilgums sekundēs. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | Izvēlieties ģenerētā video izšķirtspēju, kur 2K un 4K tiek iegūtas, palielinot 768P bāzi. Izvēloties 480P vai 768P, tiek izmantota sākotnēja ģenerēšana. |
| `seed` |  | integer \| null | no |  |  | Nejaušas ģenerēšanas sākumvērtība; ja tā nav norādīta, tā tiek izvēlēta nejauši. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Drošības pārbaudītāja aktivizēšana; true iespējo pārbaudi. |
| `prompt_expansion_mode` |  | string \| null | no | `balanced` |  | Uzvednes pārrakstīšanas intensitāte pirms ģenerēšanas: izvēlieties 'quality', lai iegūtu bagātīgāku uzvedni aptuveni līdz 30 sekunžu laikā, vai 'fast', lai rezultātu saņemtu aptuveni sekundes laikā. Izmantojot 'balanced', izvēle tiek veikta katram pieprasījumam; 'disabled' izslēdz paplašināšanu. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Izvades video malu attiecība. |
| `reference_image_urls` | `images` | array of image URL | no |  | ≤ 9 items | Objekta vai stila atsauces attēlu URL, kopā ar visām video un audio atsaucēm nepārsniedzot 12 failus. Uzvednē identificējiet šos attēlus pēc saraksta pozīcijas, izmantojot Image 1, Image 2 un turpmākos apzīmējumus. |
| `reference_video_urls` |  | array of video URL | no |  | ≤ 3 items | Kustības vai citas atsauces video URL, kas uzvednē identificēti pēc saraksta pozīcijas, izmantojot Video 1, Video 2 un turpmākos apzīmējumus. Kopējais attēlu, video un audio atsauču limits ir 12 faili; katram video klipam jāilgst 2–15 sekundes, bet kopējais ilgums nedrīkst pārsniegt 15 sekundes. |
| `reference_audio_urls` |  | array of audio URL | no |  | ≤ 3 items | Norādiet atsauces audio kā URL un identificējiet klipus uzvednē, izmantojot Audio 1, Audio 2 un turpmākos apzīmējumus. Katram klipam jāilgst 2–15 sekundes, bet kopējais audio ilgums nedrīkst pārsniegt 15 sekundes. Jebkuru attēlu, video un audio atsauces tipu var norādīt atsevišķi vai kombinēt, ievērojot kopējo 12 failu limitu. |

File parameters (`images`, `reference_video_urls`, `reference_audio_urls`) 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
{
  "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
}
```

A fuller example:

```json

  "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.ru/v1/run/minimax/h3/reference-to-video?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"
  }'

# 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"
```

### JavaScript

```javascript
const API = "https://api.doitong.ru/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/minimax/h3/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "prompt": "A red fox trots through fresh snow at sunrise, soft golden light, shallow depth of field"
  }),
});
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.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",
}

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