VEED Lipsync v2

Endpoint

POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2

Send your API key as a bearer token. The key needs the scope api:write. Every paid request also needs an Idempotency-Key header.

The envelope fields quote_only, quote_id, webhook_url and wait_timeout_seconds behave the same on each model endpoint. Refer to Jobs and Quotes and credits.

Good at

Change the script of a finished ad. Make one shoot speak a second language. Send the source video and the new audio; the model articulates the mouth of the person in the video. It is the only lipsync model that takes a video, and the only one that does not accept image_url or avatar_id. It has no prompt.

Pricing

The unit is one second. Pricing key: veed-lipsync-v2.

The credits come from the roasOS pricing table. No other field changes the price. To get the exact price of your request, send it with quote_only: true first.

Modes

• video-audio-to-video

Provider endpoints: veed/lipsync/v2.

Request fields

The schema is strict. A field that is not in this table gets 400 unsupported_option. The field names are the roasOS role names. One role has one name in every family.

Media

This endpoint accepts these media roles:

• video_url — the source video
• audio_url — the driving audio track

Every other role is refused: avatar_id, elements, product_id, product_images, references, reference_images, image_url, end_image_url, scene_id, scene_image, video_urls, audio_urls, voice_id. A refused role gets 400 unsupported_option.

Prompt

None.

Not exposed

roasOS pins no provider field for this model.

Result

The result kind is lipsync. Always present: url.

{
  "data": {
    "id": "gen_…",
    "kind": "lipsync",
    "model": "veed-lipsync-v2",
    "status": "completed",
    "result": {
      "url": "https://cdn.roasos.com/workspaces/ws_01/result"
    }
  }
}

The files are immutable objects on https://cdn.roasos.com. A result URL is a valid media input for your next request.

Example

The three steps are always the same: quote, run, poll.

# 1. Quote. Nothing is spent.
curl -X POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2 \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-veed-lipsync-v2-0001" \
  -H "Content-Type: application/json" \
  -d '{"quote_only":true,"audio_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/audio_url.mp3","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}'
# 200 { "data": { "kind": "quote", "quote_id": "q_7Hk...", "credits": 9, "expires_at": "...",
#        "confirmation": { "model": "veed-lipsync-v2", "example": "10s" } } }

# 2. Run. Same body, same Idempotency-Key, quote_id in place of quote_only.
curl -X POST https://api.roasos.com/v1/lipsync/veed-lipsync-v2 \
  -H "Authorization: Bearer roasos_sk_live_..." \
  -H "Idempotency-Key: 0f1c9e2a-veed-lipsync-v2-0001" \
  -H "Content-Type: application/json" \
  -d '{"quote_id":"q_7Hk...","audio_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/audio_url.mp3","video_url":"https://cdn.roasos.com/workspaces/ws_01/uploads/video_url.mp4"}'
# 201 { "data": { "id": "gen_...", "status": "queued", "credits_reserved": 9 } }

# 3. Poll, then read the result.
curl https://api.roasos.com/v1/jobs/gen_.../status -H "Authorization: Bearer roasos_sk_live_..."
curl https://api.roasos.com/v1/jobs/gen_.../result -H "Authorization: Bearer roasos_sk_live_..."

The deprecated path

POST /v1/generations still reaches this model for one minor version. It is deprecated. This is how it maps:

The endpoint is POST /v1/lipsync/veed-lipsync-v2 with video_url and audio_url.

The deprecated alias does not carry this model: POST /v1/generations { "type": "lipsync" } returns 503 lipsync_public_authority_unavailable for every lipsync model except ltx-lipsync, and it has no video field at all.
