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": "seedvr2-7b-upscale_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "COMPLETED",
  "model_id": "seedvr2-7b-upscale",
  "error": null,
  "output": {
    "media_url": [
      "https://pub-582b7213209642b9b995c96c95a30381.r2.dev/v1/seedvr2-7b-upscale_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx/output.png"
    ],
    "media_type": "image/png"
  },
  "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": "seedvr2-7b-upscale_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "ERROR",
  "model_id": "seedvr2-7b-upscale",
  "error": "Description of the error",
  "output": null,
  "created_at": "...",
  "updated_at": "...",
  "completed_at": "..."
}

Delivery semantics

terminal mode (default) — exactly one POST when the request reaches a terminal status. No callback during PROCESSING.
sync mode — POST on every status poll (with delay capped at ~15s) plus a final POST at terminal status. Use when you want progress updates.
Idempotency — use request_id as your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates.
Response — respond 200 OK within 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 - Image Upscale Request

Parameter	Required	Type	Default	Allowed values / range	Description
image_url	Yes	string (URI)	—	Any reachable HTTPS image URL; both source dimensions ≥ 256 px when the resolved output exceeds 1080p	Source image to upscale (PNG, JPEG, or WebP). If the resolved output exceeds 1080p, both source dimensions must be at least 256 px. A smaller source is rejected outright, not clamped — lower `upscale_factor` or the target resolution, or supply a larger image.
allow_nsfw	No	boolean	true	true, false	Runs a content-safety check on the input image and the generated result. If either is flagged, the media is hidden in your API log and deleted from storage after one hour; the request itself still completes and is billed normally. Set to `false` to skip the check.
upscale_factor	No	number	2.0	1.0 – 8.0	Scale multiplier applied to the source image. The result must also stay within roughly 100 megapixels, so the usable maximum depends on your source: `sqrt(100000000 ÷ (width × height))`. A 3008×5344 source caps at `2.5`; a 1706×2560 source caps at `4.8`; images under ~1.5 MP can use the full `8.0` only if they are also at least 256 px on both sides. A small source has a stricter, separate limit: when the resolved output exceeds 1080p the source floor of 256 px applies, so a 335×180 image is rejected at `8.0` even though the megapixel formula would allow far more. Exceeding the megapixel ceiling returns the maximum permitted for that image; breaching the 256 px source floor is rejected rather than clamped. Use either `upscale_factor` or `res_w`/`res_h`, not both.
res_h	No	integer	omit for auto	256 – 4096	Target output height in pixels. Overrides `upscale_factor` when provided. Omit the field for automatic sizing — the literal string `auto` is not an accepted value.
res_w	No	integer	omit for auto	256 – 4096	Target output width in pixels. Overrides `upscale_factor` when provided. Omit the field for automatic sizing — the literal string `auto` is not an accepted value.
output_format	No	string	png	"png", "jpg", "webp"	Encoding for the upscaled image. Use `"jpg"` for JPEG output — `"jpeg"` is not accepted.
noise_scale	No	number	0.0	0.0 – 1.0	Detail / noise injection strength. Higher values add more synthetic detail.
seed	No	integer	random	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.
job_id	No	string	auto	Any client-supplied id	Optional client-provided identifier. The gateway returns its own `request_id` regardless.

Request Parameters - Upscale Image Request

Parameter	Required	Type	Default	Allowed values / range	Description
image_url	Yes	string	—	—	The input image to upscale. Must be a publicly accessible URL (HTTPS recommended). Common formats: PNG, JPEG, WebP.
allow_nsfw	No	boolean	true	true, false	Runs a content-safety check on the input image and the generated result. If either is flagged, the media is hidden in your API log and deleted from storage after one hour; the request itself still completes and is billed normally. Set to `false` to skip the check.
upscale_mode	No	string	factor	`factor`, `target`	How to scale the image: `factor` multiplies the dimensions by `upscale_factor`; `target` upscales to a fixed `target_resolution`.
upscale_factor	No	number	2	1-10	Multiplier applied to width and height when `upscale_mode` is `factor`. Higher values produce a larger output. Values outside 1-10 are rejected.
target_resolution	No	string	1080p	`720p`, `1080p`, `1440p`, `2160p`	Target output resolution. Used only when `upscale_mode` is `target`.
noise_scale	No	number	0.1	0.0-1.0	Noise scale for the restoration process. Lower preserves fine detail and texture; higher produces a smoother, cleaner result.
output_format	No	string	jpg	`jpg`, `jpeg`, `png`, `webp`	Output image format. `jpeg` is accepted as a synonym for `jpg`.
seed	No	integer	—	—	Random seed for reproducibility. Reuse the same seed with identical settings to reproduce a result; leave empty for a different output each time.
sync_mode	No	boolean	false	`true`, `false`	If true, the finished image is returned inline as a data URI (base64) instead of a hosted URL, and is not stored in request history. Useful for quick tests; leave off for normal use.
webhook	No	string	—	—	Callback URL for completion notification. A POST request is sent with the upscaling result when processing completes.
webhook_events_filter	No	array	—	—	Which events trigger the webhook. Valid values: `["*"]` (all events) or `["completed"]` (success/failure only).

Content Item Types & Limits

Webhook (Optional)

Add the X-Webhook-URL header to your submit request to receive a POST callback when the job completes — no polling required.

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": "seedvr-upscale_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "COMPLETED",
  "model_id": "seedvr-upscale",
  "error": null,
  "output": {
    "media_url": [
      "https://pub-582b7213209642b9b995c96c95a30381.r2.dev/v1/seedvr-upscale_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": "seedvr-upscale_019dxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
  "status": "ERROR",
  "model_id": "seedvr-upscale",
  "error": "Description of the error",
  "output": null,
  "created_at": "...",
  "updated_at": "...",
  "completed_at": "..."
}

Delivery semantics

terminal mode (default) — exactly one POST when the request reaches a terminal status. No callback during PROCESSING.
sync mode — POST on every status poll (with delay capped at ~15s) plus a final POST at terminal status. Use when you want progress updates.
Idempotency — use request_id as your idempotency key. Network retries can deliver the same callback more than once; your handler must tolerate duplicates.
Response — respond 200 OK within 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 - Upscale Video Request

Parameter	Required	Type	Default	Allowed values / range	Description
video_url	Yes	string	—	—	The input video to upscale. Must be a publicly accessible URL (HTTPS recommended). Common formats: MP4, MOV, WebM.
upscale_mode	No	string	factor	`factor`, `target`	How to scale: `factor` multiplies the dimensions by `upscale_factor`; `target` upscales to a fixed `target_resolution`.
allow_nsfw	No	boolean	true	true, false	Runs a content-safety check on the input video and the generated result. If either is flagged, the media is hidden in your API log and deleted from storage after one hour; the request itself still completes and is billed normally. Set to `false` to skip the check.
upscale_factor	No	number	2	1-10	Multiplier applied to width and height when `upscale_mode` is `factor`. Higher values produce a larger output. Values outside 1-10 are rejected.
target_resolution	No	string	1080p	`720p`, `1080p`, `1440p`, `2160p`	Target output resolution. Used only when `upscale_mode` is `target`.
noise_scale	No	number	0.1	0.0-1.0	Noise scale for the restoration process. Lower preserves detail and grain; higher produces a smoother, cleaner result.
output_format	No	string	X264 (.mp4)	`X264 (.mp4)`, `VP9 (.webm)`, `PRORES4444 (.mov)`, `GIF (.gif)`	Output video container/codec.
output_quality	No	string	high	`low`, `medium`, `high`, `maximum`	Output video quality. Higher means better quality and a larger file.
output_write_mode	No	string	balanced	`fast`, `balanced`, `small`	Encoder write mode for the output video. `fast` favours encoding speed, `balanced` trades speed against file size, `small` produces the smallest file.
seed	No	integer	—	—	Random seed for reproducibility. Reuse the same seed with identical settings to reproduce a result; leave empty for a different output each time.
sync_mode	No	boolean	false	`true`, `false`	If true, the finished video is returned inline as a data URI instead of a hosted URL, and is not stored in request history. Useful for quick tests; leave off for normal use.
webhook	No	string	—	—	Callback URL for completion notification. A POST request is sent with the upscaling result when processing completes.
webhook_events_filter	No	array	—	—	Which events trigger the webhook. Valid values: `["*"]` (all events) or `["completed"]` (success/failure only).

Content Item Types & Limits

Status Flow

QUEUED → PROCESSING → COMPLETED
                    → FAILED
                    → ERROR

Typical Workflow

Send a generate request to the API endpoint
Save the request_id from the response
Poll every 5-10 seconds: GET /v2/requests/status/{request_id}
When status is "COMPLETED", download from output.media_url

Tip: Use X-Webhook-URL header to get a callback instead of polling.

SeedVR2 3B API Pricing

Your request will cost $0.12 per processed video clip.

Price scales with the output video: $0.033 × megapixels × seconds. Example: a 1080p (2.07 MP) × 10s clip ≈ $0.68.
