}Returns the text-to-image engines available to your organization, default first.
Each entry lists its
aspect_ratios, resolutions (with default_aspect_ratio
and default_resolution), max_num_outputs, credits_per_image at each
resolution, and whether it accepts trained models (supports_trained_refs) and a
color palette (supports_color_palette). The endpoint is free and needs the
images.generate scope.
Read this endpoint before calling
POST /images/generations and pass an entry’s
id as engine — an engine, aspect ratio, or resolution outside the list returns
422 before any credits are charged. A request costs credits_per_image at the
chosen resolution × num_outputs.
If your organization generates only with its trained models,
data is empty and
unavailable_reason is organization_restricted. Omit engine and pass at
least one trained model (style_id, object_ids, person_ids, setting_ids)
or a color_palette_id — see Image Generation.
For every other caller, unavailable_reason is null.Authorizations
Organization API key (Authorization: Bearer samsa_sk_...) or OAuth 2.1 access token (Authorization: Bearer samsa_at_...).
