PixVerse V6

PixVerse V6 is PixVerse's video model. One model ID covers five modes: text to video, image to video, a transition between a first and a last frame, multi-image reference, and extending a clip you already made. The mode follows the fields you send. Clips are 1–15 seconds at 360p, 540p, 720p or 1080p, with optional native audio. Send the request, keep the returned task ID, and read the finished video from the task. Images go in as URLs.

Model IDs

See the model page for current prices. For a single higher-detail shot from text or one image, see PixVerse V6 Max.

Quick example

curl https://api.seedrouter.ai/v1/videos/generations \
  -H "Authorization: Bearer $SEEDROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "pixverse-v6",
    "prompt": "A red paper boat drifting on a calm pond at sunrise, soft mist, slow push-in. No text, no logos.",
    "resolution": "540p",
    "duration": 5,
    "size": "16:9"
  }'

Endpoint

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

The response is a task ({"id": "task_...", "status": "processing"}), not the finished video. Poll GET /v1/tasks/{task_id} for the result. Keep API keys in server-side code.

Parameters

The schema is strict: unknown fields are rejected rather than ignored. callback_url is not available; poll the task instead.

Modes

The fields you send pick the mode. Send the fields of one mode per request.

{
  "model": "pixverse-v6",
  "prompt": "The puppy slowly turns into a kitten, soft studio light.",
  "first_frame_image": "https://example.com/puppy.jpg",
  "last_frame_image": "https://example.com/kitten.jpg",
  "duration": 5
}

{
  "model": "pixverse-v6",
  "prompt": "The paper boat drifts on toward a lily pad.",
  "extend_from_task_id": "task_...",
  "resolution": "540p",
  "duration": 5
}

An extend returns the source clip followed by the new segment, and bills only the new segment's duration. In our test, a 1-second extend of a 1-second clip came back 2.1 seconds long and was billed for 1 second.

Media inputs

Images are public HTTP(S) URLs. Base64 data URIs are not accepted: upload the file to your own storage and pass its URL. Use JPG, PNG or WebP images of 20 MB or less.

Pricing dimensions

Check the model pricing section for current rates. PixVerse V6 is billed per second of video, at a rate set by the resolution and by whether audio is generated:

cost = duration × rate per second for the resolution and audio setting

Every mode costs the same per second; an extend bills only the new segment. The duration is known when the request is accepted, so the amount reserved is the amount charged. View final charges in your account usage history. Failed tasks are not charged.

Output schema

Submission returns the task:

{"id": "task_...", "model": "pixverse-v6", "status": "processing", "created_at": 1789689600}

Get the task

GET https://api.seedrouter.ai/v1/tasks/{task_id}

Poll every 10–20 seconds until status is completed or failed. A network timeout while polling does not mean generation failed: keep the task ID and resume checking it. Do not create another task to check progress.

Completed task

{
  "id": "task_...",
  "model": "pixverse-v6",
  "status": "completed",
  "created_at": 1789689600,
  "finished_at": 1789689640,
  "output": {
    "video_url": "https://static.seedrouter.ai/media/tasks/task_example/0.mp4"
  }
}

In our tests 1-second 360p 16:9 clips came back as MP4 (H.264) at 640 × 360, 36–45 seconds after submission.

Errors

Requests rejected before a task is created return an HTTP error with an error object and are not charged. A task that fails after acceptance returns HTTP 200 when queried, with status: "failed" and an error object.

See the shared error catalog for codes, HTTP statuses, and retry guidance.

{
  "id": "task_...",
  "model": "pixverse-v6",
  "status": "failed",
  "error": {
    "code": 60001,
    "message": "The request was rejected by the content policy. Please revise the prompt or input images."
  }
}

If submission itself times out, check your tasks before submitting again: the first request may have been accepted.

Tips

• Describe subject, place, camera move and light in the prompt; name the sounds you want when audio is on.
• Draft at 360p or 540p, then render the final shot at 1080p with the same request and seed.
• For vertical video, send size: "9:16" with text to video, or a portrait image.
• Add no text, no logos to keep invented marks out.
