Mixed Video Models
Video model prices, request and duration billing, and reference limits.
See the unified video API for shared fields, errors and delivery. The complete catalog and OpenAPI cover all models.
Use a video-service key in the 低价混合 group and verify access with GET /v1/models. These models are configured; paid generation has not been tested.

Request fields
Create with POST /v1/videos. Required fields are model, nonempty prompt, and integer seconds within the listed range. Fast903 requires exactly 15 seconds. Use aspect_ratio for all models that support ratio control; legacy ratio remains compatible. Allowed values depend on the model catalog.
References use public URL string arrays: images, videos, and audios. Audio must be real MP3 with a URL path ending in .mp3. Fast903 does not accept video references. The Seedance face-reference models accept optional boolean face; do not send it to other models.
WAN3 Full uses its model-default resolution: omit resolution. Its request and billing contract is separate from the existing WAN3 direct models; do not add reference-video seconds to its price.
Billing
Prices are CNY balance units for the 低价混合 group. The six per-request models charge once per successful task, without multiplying by duration or reference count. WAN3 Full is billed per request.
sd2.5(全参过人脸720P) reserves requested seconds × ¥0.636: 4 seconds reserves ¥2.544 and 10 seconds reserves ¥6.36. Valid measured completion usage replaces that estimate. Missing or invalid usage retains the reservation for manual reconciliation; a request echo is not measured usage. Failed tasks follow the service refund process.

}Save the submitted task ID and poll GET /v1/videos/{id} every 15 seconds. Download from this service’s metadata.url or url on completion. Signatures last up to about 5 minutes, with about 10 minutes of storage. Do not automatically repeat creation after a 5xx or timeout.
