Verdicts

Pika API

Keyless catalogue with live prices and JSON input schemas for 162 operations. $10 a month membership before any usage, and no free generation.

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

Pika API

  1. Call GET /catalog/apis/{api_id}?expand=inputs first. It's free and returns the path, schema and price
  2. Check GET /billing/balance before a submit. A 403 can mean an inactive key or an empty balance
  3. Send an Idempotency-Key on every submit, and a fresh one only when you change the body
  4. Record cost from billing.charge_micro_usd only once billing.state is settled

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
