# H3 Max Reframe API

> Huongeza video hadi uwiano mpya wa picha, ikijaza eneo la ziada huku ikihifadhi sauti na muda wake

Hutosheleza video chanzo (sekunde 0.25 hadi 300) kwenye turubai lengwa na huzalisha eneo linaloizunguka. Chaguo za `aspect_ratio` ni 16:9, 9:16, 1:1, 4:3, 3:4, 21:9 na 9:21. `prompt` ya hiari huongoza mazingira mapya. `resolution` ni 480p, 768p au 1080p, huku 1080p ikikuzwa kutoka reframe asilia ya 768p.

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

## Pricing

Price: **from $0.05 / second of input video** (the lowest tier; the quote prices your exact input). Price per second of your input 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 input video
- 768p: $0.08 / second of input video
- 1080p: $0.16 / second of input video

The full example input below costs $0.80 = 800 API credits (10 s input video × $0.08 (768p)).

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-max/reframe-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 | no | `` | ≤ 50000 characters | Maagizo ya hiari ya eneo linalozunguka litakalozalishwa. Mchakato wa upanuzi huweka manukuu ya chanzo kiotomatiki. |
| `video_url` | `video` | string (video URL) | yes |  |  | Video chanzo iliyowekwa kwenye turubai lengwa bila kubadilisha ratiba yake ya muda au sauti. Muda unaokubalika ni kuanzia sekunde 0.25 hadi 300. |
| `aspect_ratio` |  | enum (string) | no | `16:9` | `16:9`, `9:16`, `1:1`, `4:3`, `3:4`, `21:9`, `9:21` | Uwiano wa turubai kwa upanuzi kuzunguka video chanzo. Chanzo kizima huingia ndani ya turubai hii, huku upanuzi ukijaza eneo lolote lisilofunikwa. |
| `resolution` |  | enum (string) | no | `768p` | `480p`, `768p`, `1080p` | Wasifu wa mwonekano wa turubai, huku 1080p ikipatikana kwa kuongeza latent iliyojifunzwa badala ya kurekebisha fremu kiasili katika ukubwa huo. Reframe yake ya msingi huzalishwa kiasili katika 768p. |
| `seed` |  | integer \| null | no |  | 0 – 4,294,967,295 |  |
| `enable_safety_checker` |  | boolean | no | `true` |  |  |

File parameters (`video`) 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
{
  "video": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
}
```

A fuller example:

```json
{
  "video_url": "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/minimax/h3-max/reframe-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }'

# 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-max/reframe-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
  }),
});
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 = {
    "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/minimax/h3-max/reframe-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-max/reframe-video",
      "input": {
        "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4"
      },
      "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.
