# Subtitles API

> Brænder stylede undertekster ind i en video fra automatisk transskription eller din egen SRT med valgfri oversættelse

Tilføjer renderede undertekster til en video (`video_url`) ved hjælp af en påkrævet stil-`preset`, hvor 30 forudindstillinger er tilgængelige. Den transskriberer automatisk eller springer dette over, hvis du angiver `srt_file_url` eller `srt_content`. `language` angiver kildesproget for nøjagtighed, og `translation_language` oversætter underteksterne. En `vocabulary`-liste med op til 100 termer og `customization`-tilsidesættelser finjusterer resultatet.

- 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/da/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.

Uden et målsprog forbliver underteksterne på det oprindeligt talte sprog. |
| `srt_file_url` |  | string (file URL) \| null | no |  | 1 – 2083 characters | Angiv undertekster i stedet for at køre transskription ved at uploade en .srt-fil eller indsætte dens URL. |
| `srt_content` |  | string \| null | no |  |  | Rå underteksttekst i SRT-format, angivet i stedet for srt_file_url. Angivelse af den omgår transskription. |
| `vocabulary` |  | array of object {word, replaces} \| null | no |  | ≤ 100 items | Valgfrit transskriptionsordforråd, kun aktivt når hverken srt_content eller srt_file_url er angivet. Medtag brandnavne og specialiseret jargon, som transskriptionsudbydere ofte staver forkert, f.eks. "VEED" → "vid". |
| `vocabulary[].word` |  | string | yes |  | 1 – 100 characters | Angiv den korrekte stavemåde for termen, helst et brand, produktnavn eller specialiseret term fra dit domæne. |
| `vocabulary[].replaces` |  | array of string | yes |  | 1 – 20 items | Angiv hver stavefejl én gang for at få den erstattet af `word`. Match kræver et helt ord, men ignorerer store og små bogstaver: `['vid']` matcher `vid`, `Vid` og `VID` uden separate poster for hver variant. |
| `customization` |  | object {position, shadow, text_customizations} \| null | no |  |  | Valgfri presettilpasning, der bevarer standardværdier, hvor felter udelades. Tilsidesættelser kan justere lodret placering og skyggestyrke samt skrifttype, vægt og hex-farve separat for hvert ordvigtighedsniveau. |
| `customization.position` |  | enum (string) \| null | no |  | `top`, `center`, `bottom` | Skærmposition langs den lodrette akse for statiske undertekster. |
| `customization.shadow` |  | enum (string) \| null | no |  | `none`, `min`, `mid`, `max` | Forbedring af læsbarheden for undertekster på lyse eller visuelt komplekse baggrunde. |
| `customization.text_customizations` |  | object {baseline, highlighted} \| null | no |  |  | Indstillinger for tekstens udseende efter niveau, der dækker standardord og fremhævede ord. |
| `customization.text_customizations.baseline` |  | object {font, weight, color} \| null | no |  |  | Standardudseende for al transskriptionstekst, synligt før et individuelt ord fremhæves. |
| `customization.text_customizations.highlighted` |  | object {font, weight, color} \| null | no |  |  | Styling for ord på mellemniveauet, som presets typisk fremhæver med større størrelse eller vægt. Ord placeres automatisk på dette niveau, når de markeres som bemærkelsesværdige, herunder vigtige substantiver, handlingsverber og markante 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.
