Templates and themes
Query /api/v1/capabilities for currently available template IDs, themes and account-specific limits. A template selection still creates one saved puzzle.
Images and files
Image input uses a previously uploaded or imported assetId owned by the API key account. Downloads are performed on the result page in a browser; a result URL is not a direct file URL.
Failure cases
Unknown fields or incompatible type, mode and preset combinations return 422. Inputs that cannot produce a complete puzzle also return 422. Available formats depend on configuration and account rights.
