# Subtitles API

> Brennt styliséiert Ënnertitelen an e Video, aus automatescher Transkriptioun oder Ärem eegenen SRT, mat optionaler Iwwersetzung

Füügt engem Video (`video_url`) gerenderte Ënnertitelen bäi, mat engem obligatoresche Stil-`preset`; et sinn 30 Presets verfügbar. D'Ënnertitele ginn automatesch transkribéiert, oder dës Etapp gëtt iwwersprongen, wann Dir `srt_file_url` oder `srt_content` ugitt. `language` setzt d'Quellsprooch fir méi Genauegkeet, an `translation_language` iwwersetzt d'Ënnertitelen. Eng `vocabulary`-Lëscht mat bis zu 100 Begrëffer an `customization`-Iwwerschreiwunge verbesseren d'Resultat.

- Model id: `veed/subtitles`
- Made by: VEED
- Category: Video to Video
- Output: video
- Price per minute of your input video: from $0.10 / minute of input video (cheapest run $0.10 (100 API credits))
- Run: `POST https://api.doitong.com/v1/run/veed/subtitles`
- Quote: `POST https://api.doitong.com/v1/quote/veed/subtitles`
- Docs page: https://doitong.com/lb/developers/models/veed/subtitles

## Pricing

Price: **from $0.10 / minute of input video** (the lowest tier; the quote prices your exact input). Price per minute 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:

- base rate: $0.10 / minute of input video
- above 1080p: $0.20 / minute of input video

The full example input below costs $0.20 = 200 API credits (1 min input video × $0.20).

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/veed/subtitles` 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.

| `customization` |  | object {position, shadow, text_customizations} \| null | no |  |  | Optional Preset-Personaliséierung, déi Standardwäerter fir ewechgeloossene Felder behält. Overrides kënnen déi vertikal Positioun an d'Schattestäerkt upassen, souwéi Schrëft, Gewiicht an Hex-Faarf separat fir all Wuertwichtegkeetsstuf. |

| `customization.text_customizations.baseline` |  | object {font, weight, color} \| null | no |  |  | Standard-Textausgesinn fir all Transkriptiounswierder, siichtbar ier en individuellt Wuert ervirgehuewe gëtt. |
| `customization.text_customizations.highlighted` |  | object {font, weight, color} \| null | no |  |  | Styling fir d'Wuertstuf am Mëttelrang, déi Presets normalerweis mat méi grousser Schrëft oder méi Gewiicht ervirhiewen. Wierder kommen automatesch an dës Stuf, wann se als bemierkenswäert markéiert ginn, dorënner wichteg Substantiver, Handlungsverben a markant Adjektiver. |

File parameters (`video`, `srt_file_url`) 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",
  "preset": "glass"
}
```

A fuller example:

```json
{
  "video_url": "https://content.doitong.com/video/showcase/v3/gen_fox_cartoon.mp4",
  "preset": "glass"
}
```

## 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/veed/subtitles?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",
    "preset": "glass"
  }'

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

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