# Subtitles API

> Brandt gestileerde ondertitels in een video vanuit automatische transcriptie of je eigen SRT, met optionele vertaling

Voegt gerenderde ondertitels toe aan een video (`video_url`) met een verplichte stijl-`preset`, waarbij 30 voorinstellingen beschikbaar zijn. De video wordt automatisch getranscribeerd, tenzij je `srt_file_url` of `srt_content` opgeeft. `language` stelt de brontaal in voor nauwkeurigheid en `translation_language` vertaalt de ondertitels. Een `vocabulary`-lijst met maximaal 100 termen en `customization`-overschrijvingen verfijnen het resultaat.

- 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/nl/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.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

Zonder doeltaal blijven de ondertitels in de oorspronkelijk gesproken taal. |
| `srt_file_url` |  | string (file URL) \| null | no |  | 1 – 2083 characters | Lever ondertitels aan in plaats van transcriptie uit te voeren door een .srt-bestand te uploaden of de URL ervan te plakken. |
| `srt_content` |  | string \| null | no |  |  | Onbewerkte ondertiteltekst in SRT-indeling, aangeleverd in plaats van srt_file_url. Dit omzeilt transcriptie. |
| `vocabulary` |  | array of object {word, replaces} \| null | no |  | ≤ 100 items | Optionele transcriptievocabulaire, alleen actief wanneer noch srt_content noch srt_file_url is aangeleverd. Voeg merknamen en specialistische vaktermen toe die transcriptieproviders vaak verkeerd spellen, bijvoorbeeld "VEED" → "vid". |
| `vocabulary[].word` |  | string | yes |  | 1 – 100 characters | Geef de correcte spelling van de term op, bij voorkeur een merknaam, productnaam of gespecialiseerde term uit je domein. |
| `vocabulary[].replaces` |  | array of string | yes |  | 1 – 20 items | Vermeld elke spelfout eenmaal om deze te laten vervangen door `word`. Er is een volledige woordovereenkomst vereist, maar hoofdlettergebruik wordt genegeerd: `['vid']` komt overeen met `vid`, `Vid` en `VID`, zonder afzonderlijke vermeldingen voor elke schrijfwijze. |
| `customization` |  | object {position, shadow, text_customizations} \| null | no |  |  | Optionele aanpassing van de preset, waarbij standaardwaarden behouden blijven voor weggelaten velden. Overrides kunnen verticale positie en schaduwsterkte aanpassen, evenals lettertype, gewicht en hex-kleur afzonderlijk voor elke laag van woordbelang. |
| `customization.position` |  | enum (string) \| null | no |  | `top`, `center`, `bottom` | Schermpositie langs de verticale as voor statische ondertitels. |
| `customization.shadow` |  | enum (string) \| null | no |  | `none`, `min`, `mid`, `max` | Verbetering van de leesbaarheid van ondertitels tegen lichte of visueel drukke achtergronden. |
| `customization.text_customizations` |  | object {baseline, highlighted} \| null | no |  |  | Instellingen voor tekstweergave per laag, voor basiswoorden en gemarkeerde woorden. |
| `customization.text_customizations.baseline` |  | object {font, weight, color} \| null | no |  |  | Standaardweergave van tekst voor alle transcriptiewoorden, zichtbaar voordat een afzonderlijk woord nadruk krijgt. |
| `customization.text_customizations.highlighted` |  | object {font, weight, color} \| null | no |  |  | Styling voor de middelste woordlaag, die presets doorgaans benadrukken met een grotere grootte of hoger gewicht. Woorden komen automatisch in deze laag wanneer ze als opvallend zijn gemarkeerd, waaronder belangrijke zelfstandige naamwoorden, werkwoorden en opvallende bijvoeglijke naamwoorden. |

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.
