Gerar imagens
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.
Opções de dimensionamento
Os modelos de imagem usam parâmetros de dimensionamento específicos por modelo:- Modelos baseados em pixels aceitam
widtheheight, por exemplovenice-sd35eqwen-image. - Modelos baseados em proporção de aspecto aceitam
aspect_ratio, por exemploqwen-image-2. - Modelos com níveis de resolução aceitam tanto
aspect_ratioquantoresolution.
gpt-image-2, nano-banana-2 e nano-banana-pro suportam valores de resolution de 1K, 2K e 4K:
aspect_ratio sem resolution:
width e height em vez disso:
Níveis de qualidade
Alguns modelos aceitam um parâmetro opcionalquality (low, medium, high) que troca fidelidade visual por custo. Atualmente suportado por gpt-image-2; outros modelos ignoram o parâmetro.
quality, o modelo usa seu nível padrão (high para gpt-image-2). O preço depende da combinação de resolution e quality — os preços por nível para gpt-image-2 (1K/2K/4K × low/medium/high) são expostos em model_spec.pricing.quality no endpoint de Modelos e listados na visão geral de preços.
quality são cobradas pelo nível padrão do modelo (high para gpt-image-2).Coleção do Postman

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Cabeçalhos
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
