# Subtitles API

> Bränner in formaterade undertexter i en video från automatisk transkribering eller egen SRT, med valfri översättning

Lägger till renderade undertexter i en video (`video_url`) med en obligatorisk formatförinställning `preset`, med 30 tillgängliga förinställningar. Den transkriberar automatiskt eller hoppar över detta om du anger `srt_file_url` eller `srt_content`. `language` anger källspråket för bättre träffsäkerhet, och `translation_language` översätter undertexterna. En `vocabulary`-lista med upp till 100 termer och åsidosättningar i `customization` finjusterar 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/sv/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.

Utan målspråk förblir undertexterna på det ursprungliga talade språket. |
| `srt_file_url` |  | string (file URL) \| null | no |  | 1 – 2083 characters | Tillhandahåll undertexter i stället för att köra transkribering genom att ladda upp en .srt-fil eller klistra in dess URL. |
| `srt_content` |  | string \| null | no |  |  | Rå undertexttext i SRT-format, angiven i stället för srt_file_url. Om den tillhandahålls kringgås transkriberingen. |
| `vocabulary` |  | array of object {word, replaces} \| null | no |  | ≤ 100 items | Valfritt transkriberingsordförråd, aktivt endast när varken srt_content eller srt_file_url anges. Inkludera varumärken och fackjargong som transkriberingsleverantörer ofta stavar fel, till exempel "VEED" → "vid". |
| `vocabulary[].word` |  | string | yes |  | 1 – 100 characters | Ange korrekt stavning av termen, helst ett varumärke, produktnamn eller specialiserat begrepp från din domän. |
| `vocabulary[].replaces` |  | array of string | yes |  | 1 – 20 items | Lista varje felstavning en gång för att ersätta den med `word`. Matchningen kräver ett helt ord men ignorerar versaler och gemener: `['vid']` matchar `vid`, `Vid` och `VID` utan separata poster för varje variant. |
| `customization` |  | object {position, shadow, text_customizations} \| null | no |  |  | Valfri anpassning av förinställningen, där standardvärden behålls för alla utelämnade fält. Åsidosättningar kan justera vertikal placering och skuggstyrka samt teckensnitt, vikt och hex-färg separat för varje ordviktighetsnivå. |
| `customization.position` |  | enum (string) \| null | no |  | `top`, `center`, `bottom` | Skärmposition längs den vertikala axeln för statiska undertexter. |
| `customization.shadow` |  | enum (string) \| null | no |  | `none`, `min`, `mid`, `max` | Läsbarhetsförbättring för undertexter mot ljusa eller visuellt röriga bakgrunder. |
| `customization.text_customizations` |  | object {baseline, highlighted} \| null | no |  |  | Inställningar för textens utseende per nivå, som omfattar basord och markerade ord. |
| `customization.text_customizations.baseline` |  | object {font, weight, color} \| null | no |  |  | Standardutseende för all transkriberad text, synligt innan ett enskilt ord får betoning. |
| `customization.text_customizations.highlighted` |  | object {font, weight, color} \| null | no |  |  | Stil för ord på mellannivå, som förinställningar vanligtvis betonar med större storlek eller vikt. Ord hamnar automatiskt på denna nivå när de markeras som anmärkningsvärda, inklusive viktiga substantiv, handlingsverb och framträdande adjektiv. |

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.
