Request Body

{
    "email": "Optional PixVerse API account email",
    "prompt": "Required modification prompt",
    "video_id": "Optional video_id",
    "quality": "540p",
    "seed": 654321,
    "replyUrl": "Place your call back URL here",
    "replyRef": "Place your reference id here",
    "maxJobs": 3
}

email is optional, if not specified API will randomly select account from available accounts.
model is optional.
Supported values: v5.5 (default).
prompt is required, describe the modification you want to apply.
Maximum length 5,000 characters.
video_id is optional, retrieve the video_id of the desired video using GET /videos.
video_path is optional, upload the video using POST /files and use path to specify the video you want to modify.
quality is optional. Video quality.
Supported values: 720p, 540p (default), 360p.
seed is optional.
Valid range 1…2147483647.
off_peak_mode is optional. Set to true to generate videos during low-demand periods at a reduced credit cost. Only supported for native PixVerse models (v5, v5.5, v5.6, v5-fast, v6, pixverse-c1) — third-party models reject this flag. Discount varies by subscription plan: Pro 30% off, Premium 50% off, Ultra unlimited free. Results are usually delivered within 24 hours. Off-Peak generations are not tracked by the scheduler, don’t count toward concurrent-job limits, and the replyUrl webhook is not called — use GET videos to retrieve results.
Supported values: false (default), true.
replyUrl is optional. This is the preferred and most optimal way to receive results quickly — the API polls every 10 seconds and will call the provided replyUrl once the PixVerse video is completed or failed. Maximum length 1024 characters. We recommend using sites like webhook.site to test callback URL functionality. Callback body has the same JSON shape as GET /videos/video_id response.
replyRef is optional, place here your reference id which will be stored and returned along with this PixVerse video response / result.
Maximum length 1024 characters.
maxJobs is optional, if not specified value from selected accounts/email will be used.
Valid range: 1…8
It should not exceed the number of concurrent generations supported by your account subscription plan.

Responses

200 OK

Use the returned video_id to retrieve video status and results using GET /videos. Locate the video in the response array and check if the field video_status_final is true or video_status_name is COMPLETED. The field url will contain the generated video link.

If you specify the optional parameter replyUrl, the API will call the provided replyUrl with video progress updates until the video is complete or fails.

Wait in a loop for at least 10..30 seconds and retry again.

There are two possible cases for API response 429:
1. API query is full and can not accept new videos/modify requests. Size of query defined by maxJobs optional parameter.
```
{
 "error":
   "Account <email> is busy executing <maxJobs> tasks."
   "All configured accounts are running at maximum capacity."
}
```
2. The API received an HTTP response status 429 from PixVerse. Please refer to your subscription plan for the maximum allowed tasks in the queue.
```
{
  "error": "Reached the limit for concurrent generations."
}
```

596 Pending mod message

The account has a pending error, and the API does not use it until you add it again with POST accounts/email. You receive an email when this happens. There are two causes.

PixVerse could not sign the account in, most often because its password was changed. Add the account again with the current password.

{
  "error": "Your PixVerse account has pending error. Please address this issue at https://useapi.net/docs/api-pixverse-v2/post-pixverse-accounts-email before making any new API calls.",
  "code": 596
}

Or PixVerse suspended the account. PixVerse suspends accounts that break its content rules and does not say which generation caused it. The first response carries PixVerse’s own details in account_moderation, and later calls return the same error. Add the account again after reinstatement_at. To ask PixVerse to lift the suspension earlier, write to the support_email it gives.

{
  "error": "PixVerse suspended account [email protected] for 30 days, from 2026-10-16 09:26 UTC until 2026-11-15 09:26 UTC. PixVerse suspends accounts that break its content rules and does not say which generation caused it. Add the account again at https://useapi.net/docs/api-pixverse-v2/post-pixverse-accounts-email after 2026-11-15 09:26 UTC. To ask PixVerse to lift it earlier, write to [email protected].",
  "code": 596,
  "account_moderation": {
    "ban_level": "suspend_30d",
    "action": "temporary_suspend",
    "duration_days": 30,
    "suspended_at": "2026-10-16 09:26:25 (UTC)",
    "reinstatement_at": "2026-11-15 09:26:25 (UTC)",
    "support_email": "[email protected]"
  }
}

If every account you have is in this state, a request without email returns 596 as well.
