Genera immagini
Generate an image based on input parameters
Authentication: This endpoint accepts either a Bearer API key or a SIGN-IN-WITH-X header for x402 wallet-based authentication. The legacy X-Sign-In-With-X header is also accepted during migration. When using x402, a 402 Payment Required response indicates insufficient balance and includes top-up instructions.
Opzioni di dimensionamento
I modelli di immagine usano parametri di dimensionamento specifici per modello:- I modelli basati su pixel accettano
widtheheight, ad esempiovenice-sd35eqwen-image. - I modelli basati su aspect ratio accettano
aspect_ratio, ad esempioqwen-image-2. - I modelli a livelli di risoluzione accettano sia
aspect_ratiosiaresolution.
gpt-image-2, nano-banana-2 e nano-banana-pro supportano i valori di resolution 1K, 2K e 4K:
aspect_ratio senza resolution:
width e height:
Livelli di qualità
Alcuni modelli accettano un parametro opzionalequality (low, medium, high) che bilancia fedeltà visiva e costo. Attualmente supportato da gpt-image-2; gli altri modelli ignorano il parametro.
quality, il modello usa il proprio livello predefinito (high per gpt-image-2). Il prezzo dipende dalla combinazione di resolution e quality — i prezzi per livello per gpt-image-2 (1K/2K/4K × low/medium/high) sono esposti sotto model_spec.pricing.quality nell’endpoint Models ed elencati nella panoramica dei prezzi.
quality vengono fatturate al livello predefinito del modello (high per gpt-image-2).Postman Collection

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Intestazioni
Supported compression encodings (gzip, br). Only applied when return_binary is false.
"gzip, br"
Corpo
The model to use for image generation.
"grok-imagine-image"
The description for the image. Character limit is model specific and is listed in the promptCharacterLimit setting in the model list endpoint.
1 - 7500"A beautiful sunset over a mountain range"
CFG scale parameter. Higher values lead to more adherence to the prompt.
0 < x <= 207.5
Embed prompt generation information into the image's EXIF metadata.
false
The image format to return. WebP are smaller and optimized for web use. PNG are higher quality but larger in file size.
jpeg, png, webp "webp"
Height of the generated image.
0 < x <= 12801024
Whether to hide the Venice watermark. Venice may ignore this parameter for certain generated content.
false
This feature is deprecated and was disabled on May 19th, 2025. A revised in-painting API will be launched in the near future.
Lora strength for the model. Only applies if the model uses additional Loras.
0 <= x <= 10050
A description of what should not be in the image. Character limit is model specific and is listed in the promptCharacterLimit constraint in the model list endpoint.
7500"Clouds, Rain, Snow"
Whether to return binary image data instead of base64.
false
Number of images to generate (1–4). Only supported when return_binary is false.
1 <= x <= 43
Whether to use safe mode. If enabled, this will blur images that are classified as having adult content.
false
Random seed for generation. If not provided, a random seed will be used.
-999999999 <= x <= 999999999123456789
Number of inference steps. This model does not support steps - this field is ignored.
8
An image style to apply to the image. Visit https://docs.venice.ai/api-reference/endpoint/image/styles for more details.
"3D Model"
Aspect ratio (utilized by certain image models including Nano Banana). Examples: "1:1", "16:9".
"1:1"
Resolution (utilized by certain image models including Nano Banana). Examples: "1K", "2K", "4K".
"1K"
Output quality for supported models (e.g. GPT Image 2 / GPT Image 2 Edit). Higher values can increase the final request charge. See the model list for supported options.
low, medium, high "high"
Enable web search for the image generation task. This will allow the model to use the latest information from the web to generate the image. Only supported by certain models. If web search is used, additional credits are getting charged.
false
Width of the generated image.
0 < x <= 12801024
