Media Generation

Generate video and audio from text prompts. These are DOS AI extension endpoints (not part of the OpenAI API).

• Video generation is asynchronous: create a job, then poll for the result.
• Audio (music) generation is synchronous: the response includes the audio URL directly.

All media-generation endpoints use the same API key authentication as the rest of the API:

Authorization: Bearer dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Video Generation

Create a video

POST https://api.dos.ai/v1/videos/generations

Request Body

Parameter	Type	Required	Default	Description
prompt	string	Yes	-	Text description of the video to generate.
model	string	No	wan-t2v	Video model ID. See Video Models.
duration	integer	No	5	Length of the video in seconds.
resolution	string	No	provider default	Output resolution, e.g. 720p, 1080p.
image_url	string	No	-	A source image URL. Providing it switches the model to its image-to-video variant.

Response (202 Accepted)

Video generation runs in the background. The call returns immediately with a task_id you use to poll for the result.

{
  "id": "req-1a2b3c",
  "task_id": "task-abc123",
  "status": "processing",
  "model": "wan-t2v",
  "provider": "alibaba"
}

Video Models

Model ID	Description
wan-t2v (default)	Wan 2.7 text-to-video
wan2.7-t2v	Wan 2.7 text-to-video
wan-i2v / wan2.7-i2v	Wan 2.7 image-to-video
wan2.6-t2v	Wan 2.6 text-to-video
wan2.6-i2v	Wan 2.6 image-to-video

When image_url is supplied with a text-to-video model, DOS AI automatically routes to that model's image-to-video variant.

Get video status

GET https://api.dos.ai/v1/videos/generations/{task_id}

Poll this endpoint (using the task_id from the create call) until status is succeeded or failed.

{
  "task_id": "task-abc123",
  "status": "succeeded",
  "provider": "alibaba",
  "data": [
    { "url": "https://.../video.mp4" }
  ]
}

status	Meaning
processing	The job is still running. Keep polling.
succeeded	Done. data[].url holds the generated video URL.
failed	Generation failed. message contains the reason.

Audio (Music) Generation

POST https://api.dos.ai/v1/audio/generations

Generates music from a text prompt and/or lyrics. This call is synchronous and typically takes 30-60 seconds.

Request Body

Parameter	Type	Required	Default	Description
prompt	string	Yes*	-	Description / style of the music.
lyrics	string	Yes*	-	Lyrics for the song.
model	string	No	minimax-music-2.5	Audio model ID.
duration	integer	No	180	Target length in seconds.
instrumental	boolean	No	false	Generate an instrumental track (no vocals).

* Provide at least one of prompt or lyrics.

Response (200 OK)

{
  "id": "trace-xyz789",
  "created": 1718000000,
  "model": "minimax-music-2.5",
  "provider": "minimax",
  "data": [
    { "url": "https://.../music.mp3", "duration": 30.0 }
  ]
}

Audio is returned as a direct URL (MP3, 44.1 kHz, 256 kbps). data[0].duration is the actual length in seconds.

Examples

Generate a video, then poll for it (cURL)

# 1. Create the job
curl https://api.dos.ai/v1/videos/generations \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" \
  -d '{
    "prompt": "A red panda surfing a wave at sunset, cinematic",
    "model": "wan-t2v",
    "duration": 5,
    "resolution": "720p"
  }'
# -> {"id":"req-...","task_id":"task-abc123","status":"processing",...}

# 2. Poll until succeeded
curl https://api.dos.ai/v1/videos/generations/task-abc123 \
  -H "Authorization: Bearer dos_sk_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
# -> {"task_id":"task-abc123","status":"succeeded","data":[{"url":"https://.../video.mp4"}]}

Generate music (cURL)
