Genera immagini
Invia un job di generazione di immagini — prompt più modelli addestrati facoltativi — e ottieni un id del job.
202 Accepted con un id del job; interroga
GET /images/generations/{id} per il
risultato. Combina i modelli addestrati della tua organizzazione passando i loro id
o i loro nomi — style_id, object_ids, person_ids, setting_ids — più un
color_palette_id. Ogni riferimento accetta un nome o un id che si risolve a un
modello o a una palette visibile a te.
Esempio: comporre più modelli addestrati
Passa un modellostyle, uno o più modelli person e setting e una color
palette insieme in un’unica richiesta. Ogni riferimento a un modello — tramite id o
nome — deve risolversi a un modello completed visibile a te.
object_ids, person_ids e setting_ids sono array; style_id e
color_palette_id accettano un singolo valore (un nome o un id). num_outputs
(1–4) ha come valore predefinito 1 e ogni output viene addebitato. Ometti
engine per usare il predefinito nano_banana_pro. aspect_ratio accetta 1:1
(predefinito), 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9,
1:4, 4:1, 1:8 e 8:1; un rapporto non supportato restituisce 422 prima
che vengano addebitati credits.Autorizzazioni

Corpo
POST /images/generations body (ADR §8, §10).
Trained-model refs (style_id, object_ids, person_ids, setting_ids) and the
color_palette_id color-palette ref combine on the Gemini path — each accepts a NAME
or its UUID id, resolved within your visible set (a model/palette you own, including
private ones, or a non-private one shared within your organization); setting_ids
maps to the internal scene_ids (ADR §8.2). engine is a public-safe subset of the
image engines (ADR §8.3). Note num_outputs defaults to 1 for API
ergonomics — the internal app default is 4.
Text prompt. Runs the same validation as the app (rejects empty / malformed / policy-violating prompts with a 422).

A style model NAME or its UUID id (from list_models), resolved within your visible set — a model you own (including your own private models) or a non-private one shared with your organization. A name matching more than one visible model is rejected — pass the id. Must be completed.
object models to compose in — each a model NAME or its UUID id (from list_models), resolved within your visible set (a model you own, including private, or a non-private one your organization shares). A name matching more than one visible model is rejected — pass the id.
person models to compose in — each a model NAME or its UUID id (from list_models), resolved within your visible set (a model you own, including private, or a non-private one your organization shares). A name matching more than one visible model is rejected — pass the id.
setting models to compose in — each a model NAME or its UUID id (from list_models), resolved within your visible set (a model you own, including private, or a non-private one your organization shares). A name matching more than one visible model is rejected — pass the id. Maps to internal scenes.
A color palette NAME or its UUID id, resolved within your visible set — a palette you created (including private ones) or a non-private palette shared with your organization. A name matching more than one visible palette is rejected — pass the id.
Generation engine — one of nano_banana_pro (default) or nano_banana_2. Omit to use the default. Unknown engines return 422.
"nano_banana_pro"
Number of images to generate (1-4). Defaults to 1 (the app default is 4); each output is billed.
1 <= x <= 41
Aspect ratio for the generated image(s). One of 1:1 (default), 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 21:9, 1:4, 4:1, 1:8, 8:1. Unsupported ratios return 422 before any credits are charged.
"1:1"
Output resolution — 1K, 2K, or 4K. Credits scale 1K:1x, 2K:2x, 4K:4x per output.
"1K"
Encoding of the returned images. v1 supports png only.
png "png"
Optional https webhook notified once on terminal status (signed per the webhook signature scheme; see the webhooks docs).
