# MiniMax H3 Reference to Video API

> Myndband úr allt að 9 mynd-, 3 myndbands- og 3 hljóðviðmiðum, 5 til 15 sekúndur, allt að 4K

Myndar myndband úr `prompt` sem vísar til viðmiða eftir röð, svo sem Image 1, Video 1 eða Audio 1. Gefðu upp allt að 9 myndir, 3 myndbandsbúta og 3 hljóðbúta, að hámarki 12 skrár samtals. `duration` er 5 til 15 sekúndur, `resolution` er 480P, 768P, 2K eða 4K og `aspect_ratio` inniheldur adaptive, 21:9, 16:9, 4:3, 1:1, 3:4 og 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.com/v1/run/minimax/h3/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/minimax/h3/reference-to-video`
- Docs page: https://doitong.com/is/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.com/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 | Leiðbeiningar fyrir myndbandsgerð með tilvísunum sem eru auðkenndar eftir gerð og staðsetningu í hverjum tilvísanalista, með merkjum á borð við Audio 1, Video 1, Image 1, Image 2 og svo framvegis. |
| `duration` |  | integer | no | `5` | 5 – 15 | Lengd myndbands, mæld í sekúndum. |
| `resolution` |  | enum (string) | no | `2K` | `480P`, `768P`, `2K`, `4K` | Veldu upplausn myndaðs myndbands; 2K og 4K fást með uppstærðingu á 768P-grunni. Val á 480P eða 768P notar í staðinn upprunalega efnisgerð. |
| `seed` |  | integer \| null | no |  |  | Sáð fyrir slembna efnisgerð; ef það er sleppt er eitt valið af handahófi. |
| `enable_safety_checker` |  | boolean | no | `true` |  | Virkjun öryggisathugunar; true virkjar athugun. |
| `prompt_expansion_mode` |  | string \| null | no | `balanced` |  | Vinnsla við endurskrifun kvaðningar fyrir efnisgerð: veldu 'quality' fyrir ríkari kvaðningu sem tekur allt að um 30 sekúndur eða 'fast' fyrir niðurstöðu á um það bil sekúndu. Með 'balanced' er valið fyrir hverja beiðni; 'disabled' slekkur á útvíkkun. |
| `aspect_ratio` |  | enum (string) | no | `adaptive` | `adaptive`, `21:9`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | Stærðarhlutfall úttakmyndbandsins. |

Auðkenndu þessar myndir í kvaðningunni eftir stöðu í listanum með Image 1, Image 2 og síðari merkjum. |
| `reference_video_urls` |  | array of video URL | no |  | ≤ 3 items | Slóðir á tilvísunarmyndbönd fyrir hreyfingu eða annað, auðkennd eftir stöðu í kvaðningunni með Video 1, Video 2 og síðari merkjum. Sameiginlegt hámark fyrir myndir, myndbönd og hljóð er 12 skrár; hvert myndband verður að vera 2–15 sekúndur og samanlagt að hámarki 15 sekúndur. |
| `reference_audio_urls` |  | array of audio URL | no |  | ≤ 3 items | Gefðu upp tilvísunarhljóð sem slóðir og auðkenndu bútana í kvaðningunni með Audio 1, Audio 2 og síðari merkjum. Hver bútur verður að vera 2–15 sekúndur og heildarhljóðið að hámarki 15 sekúndur. Hægt er að gefa upp hvaða gerð tilvísunar sem er ein sér eða saman, með sameiginlegu hámarki 12 skráa. |

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.com/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.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/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.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",
}

# 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.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": "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.
