Callbacks + polling ensure reliable completion. Auto‑refund on failure.

Seedream API clients need a current model name and explicit edit inputs

Choose generation or edit mode, validate the source images and send only supported fields from this reference. Save the returned identifier and surface provider failures rather than replacing them with a generic timeout.

Read the current credit estimate shown here. Do not promise local execution or a free API key unless the product explicitly offers it.
