Verdicts

MiniMax Video API

2K with stereo audio at $0.13 a second, 768P at $0.08. No statement found on whether API inputs train models, and the privacy policy needs a browser.

Seedance on BytePlus ModelArk

The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

Before you call either

MiniMax Video API

  1. Use POST /v2/video_generation for H3 and poll GET /v2/query/video_generation/{task_id}. Tasks stay queryable for 7 days
  2. Set ratio for text-to-video. adaptive isn't allowed there
  3. Pass callback_url to skip polling. Your endpoint must echo the challenge within 3 seconds
  4. A 402 means the balance is empty and a 422 means moderation blocked the content. Don't retry either unchanged

Seedance on BytePlus ModelArk

  1. POST to /api/v3/contents/generations/tasks on ark.ap-southeast.bytepluses.com, then poll GET /contents/generations/tasks/{id} or pass callback_url. Callbacks need an answer within 5 seconds
  2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
  3. Pass resolution, ratio and duration in the request body. Parameters appended to the prompt as --rs or --dur are weakly validated and may be ignored
  4. On Seedance 2.5 set omni_reference_task_type to edit or extend so constraint errors arrive at submission. With auto they arrive after the task leaves the queue
  5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
