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.
Options de dimensionnement
Les modèles d’image utilisent des paramètres de dimensionnement spécifiques au modèle :- Les modèles basés sur les pixels acceptent
widthetheight, par exemplevenice-sd35etqwen-image. - Les modèles basés sur le ratio d’aspect acceptent
aspect_ratio, par exempleqwen-image-2. - Les modèles à niveaux de résolution acceptent à la fois
aspect_ratioetresolution.
gpt-image-2, nano-banana-2 et nano-banana-pro prennent en charge les valeurs resolution de 1K, 2K et 4K :
aspect_ratio sans resolution :
width et height :
Niveaux de qualité
Certains modèles acceptent un paramètrequality optionnel (low, medium, high) qui arbitre entre fidélité visuelle et coût. Actuellement pris en charge par gpt-image-2 ; les autres modèles ignorent ce paramètre.
quality, le modèle utilise son niveau par défaut (high pour gpt-image-2). Le prix dépend de la combinaison de resolution et quality — les prix par niveau pour gpt-image-2 (1K/2K/4K × low/medium/high) sont exposés sous model_spec.pricing.quality dans l’endpoint Models et listés dans l’aperçu de la tarification.
quality sont facturées au niveau par défaut du modèle (high pour gpt-image-2).Collection Postman

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
En-têtes
Supported compression encodings (gzip, br). Only applied when return_binary is false.
"gzip, br"
Corps
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
