Price per SKU

Wan 3.0 is $0.0625 per second at 480p, $0.125 at 720p and $0.25 at 1080p, with a range of 2 to 30 seconds. Use the still as the first frame so the product looks the same as in your catalog.

A first-frame request

Ask /v1/videos/models which frame_images types the model accepts before you send them. A first frame goes in frame_images with frame_type: first_frame.

Limits and gotchas

• Generated product shots can drift from the real product. Compare each with the catalog picture before you publish.
• Send an Idempotency-Key per SKU and version so a rerun does not bill twice.
• Poll polling_url, then download from unsigned_urls[0].
