Webhook (Optional)
Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.
Using curl? These are HTTP request headers — pass each with -H, e.g. -H "X-Webhook-URL: https://your-server.com/webhook/callback". Do not paste them as bare lines, and end every line of a multi-line command with \.
Webhook Headers
| Header | Required | Default | Description |
|---|---|---|---|
X-Webhook-URL | Yes (to enable) | — | HTTPS endpoint on your server that will receive the POST callback. Must respond 2xx within a few seconds (process async if needed). |
X-Webhook-Mode | No | terminal | terminal — fires once at the final status (COMPLETED/FAILED/ERROR). sync — fires on every poll cycle plus the terminal event, and caps the queue’s polling delay at 15s for tighter progress updates. |
Example: enable webhook
X-Webhook-URL: https://your-server.com/webhook/callback
X-Webhook-Mode: terminal
Callback Payload
Your endpoint receives a POST application/json with the same shape as the GET /v2/requests/status/{request_id} response. Example terminal callback (mode terminal):
{
"request_id": "baidu-genflare-2-0-api_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "COMPLETED",
"model_id": "baidu-genflare-2-0-api",
"error": null,
"output": {
"media_url": [
"https://pub-582b7213209642b9b995c96c95a30381.r2.dev/v1/baidu-genflare-2-0-api_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/output.mp4"
],
"media_type": "video/mp4"
},
"created_at": "2026-05-22T13:17:32.110Z",
"updated_at": "2026-05-22 13:19:23",
"completed_at": "2026-05-22 13:19:23"
}
Failure callback shape
{
"request_id": "baidu-genflare-2-0-api_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
"status": "ERROR",
"model_id": "baidu-genflare-2-0-api",
"error": "Description of the error",
"output": null,
"created_at": "...",
"updated_at": "...",
"completed_at": "..."
}
Delivery semantics
- terminal mode (default) — exactly one
POSTwhen the request reaches a terminal status. No callback duringPROCESSING. - sync mode —
POSTon every status poll (with delay capped at ~15s) plus a finalPOSTat terminal status. Use when you want progress updates. - Idempotency — use
request_idas your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates. - Response — respond
200 OKwithin a few seconds. The queue does not block on slow handlers, but persistent failures may stop further deliveries. - HTTPS required — plain
http://URLs are rejected.
Request Parameters - Generate Image To Video
| Parameter | Required | Type | Default | Allowed values / range | Description |
|---|---|---|---|---|---|
| img_url | Yes | string | — | JPEG, JPG, PNG (no alpha), BMP, WEBP; 240-8000 px per side; up to 20 MB | Public URL (or Base64 data) of the first-frame image. The video starts from this picture. |
| prompt | No | string | — | Up to 1,500 characters | Text description of the video to generate. Supports English and Chinese; longer text is truncated. |
| negative_prompt | No | string | — | Up to 500 characters | Elements to exclude from the video. Supports English and Chinese. |
| audio_url | No | string | — | WAV, MP3; 3-30 seconds; up to 15 MB | Public URL of a custom audio file to use as the video's soundtrack. If set, it is used instead of auto-generated audio. |
| resolution | No | string | 1080P | 480P, 720P, 1080P | Output resolution tier: 480P (832x480), 720P (1280x720), 1080P (1920x1080). |
| duration | No | integer | 5 | 5, 10 | Video length in seconds. |
| audio | No | boolean | false | true, false | Audio behavior: false generates a silent video; true auto-generates matching audio (background music or sound effects). Use audio_url to supply your own audio track. |
| prompt_extend | No | boolean | true | true, false | Automatically rewrites and enriches your prompt with extra detail before generation to improve results. |
| watermark | No | boolean | false | true, false | Adds an "AI Generated" watermark to the lower-right corner of the video. |
| seed | No | integer | — | 0 - 2147483647 | Random seed that controls the generation's randomness. Reuse the same seed with identical settings to reproduce the same result; leave it empty for a different output each time. |
Content Item Types & Limits
| Type | Max | Format / Size | Description |
|---|---|---|---|
| image | 1 | JPG, PNG, WEBP | Input image to animate. |

⚡ Performance
Live usage measured on Pixazo's gateway, split by model version. Generation time is how long a generation takes end-to-end (lower is better). Success rate is the percent of generations that complete (higher is better).
〰 Uptime
Percent of generations that succeeded over the selected period, per model version.
