# Flux 3 Text To Video Draft API

> صرف متنی پرامپٹ سے تخلیق کردہ ڈرافٹ ویڈیو، اختیاری آڈیو کے ساتھ

Flux 3 draft سیٹ کا صرف ٹیکسٹ والا اندراج۔ ایک `prompt` فراہم کریں، `aspect_ratio` (auto یا 21:9 سے 9:16) اور `duration` (auto یا مکمل سیکنڈز) منتخب کریں، اور طے کریں کہ `generate_audio` فعال ہو یا نہیں۔ `safety_tolerance` 0 سے 4 تک ہے۔ مکمل معیار کی رینڈرنگ کے لیے `draft_cache` واپس کیا جاتا ہے۔

- Model id: `blackforestlabs/flux-3/text-to-video/draft`
- Made by: Black Forest Labs
- Category: Text to Video
- Output: video
- Price: $0.06 / second (5 s ≈ $0.30) (cheapest run $0.30 (300 API credits))
- Run: `POST https://api.doitong.ru/v1/run/blackforestlabs/flux-3/text-to-video/draft`
- Quote: `POST https://api.doitong.ru/v1/quote/blackforestlabs/flux-3/text-to-video/draft`
- Docs page: https://doitong.com/ur/developers/models/blackforestlabs/flux-3/text-to-video/draft

## Pricing

Price: **$0.06 / second (5 s ≈ $0.30)**. Billed per second of output (`duration`, default 20).

The full example input below costs $1.20 = 1200 API credits (20 s × 60 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/blackforestlabs/flux-3/text-to-video/draft` 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

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `prompt` |  | string | yes |  |  | ڈرافٹ ویڈیو کی متنی وضاحت۔ |
| `aspect_ratio` |  | enum (string) | no | `auto` | `auto`, `21:9`, `2:1`, `16:9`, `4:3`, `1:1`, `3:4`, `9:16` | ڈرافٹ آؤٹ پٹ کا پہلو تناسب؛ `auto` انتخاب ماڈل کے سپرد کرتا ہے۔ |
| `duration` |  | enum | no | `auto` | `auto`, `5`, `6`, `7`, `8`, `9`, `10`, `11`, `12`, `13`, `14`, `15`, `16`, `17`, `18`, `19`, `20` | ڈرافٹ کی لمبائی، 5 سے 20 سیکنڈ تک عدد صحیح یا `auto` کے طور پر۔ |
| `generate_audio` |  | boolean | no | `true` |  | ڈرافٹ ویڈیو کے لیے آڈیو کی تخلیق کو کنٹرول کرتا ہے۔ |

## 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/blackforestlabs/flux-3/text-to-video/draft?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/blackforestlabs/flux-3/text-to-video/draft?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/blackforestlabs/flux-3/text-to-video/draft", 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": "blackforestlabs/flux-3/text-to-video/draft",
      "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.

### Output fields (`output`)

| Field | Type | Description |
|---|---|---|
| `video` | object {url, content_type, file_name, file_size} | ڈرافٹ کے طور پر تیار کردہ ویڈیو۔ |
| `draft_cache` | object {url, content_type, file_name, file_size} \| null | `draft-enhance` کے ذریعے مکمل معیار میں ڈرافٹ رینڈر کرنے کے لیے کیش ڈیٹا، پائیدار انکرپٹڈ بنڈل میں محفوظ۔ اگر پارٹنر نے ڈرافٹ کے لیے کوئی بنڈل واپس نہ کیا ہو تو یہ آؤٹ پٹ موجود نہیں ہوتا۔ |
