Input Parameters

Parameter	Type	Required	Default	Description
prompt	string	Yes	—	Text description of the image you want to generate
ratio	string	No	1:1	Aspect ratio (1:1, 16:9, 9:16, 4:3, 3:4, 21:9, 9:21, 3:2, 2:3, 2:1, 1:2)

Example input:

{
  "prompt": "A beautiful sunset over mountains with vibrant orange and purple colors",
  "ratio": "16:9"
}

Sample Output

{
  "ok": true,
  "imageUrl": "https://api.apify.com/v2/key-value-stores/...",
  "savedImageKey": "generated-image.png",
  "imageBase64": "data:image/png;base64,iVBORw0KGgoAAAANS..."
}

• imageUrl: public URL to view/download the generated image
• savedImageKey: key for accessing the image in the key-value store
• imageBase64: base64-encoded image data (useful for local development)

How to Use the AI Image Generator

1. Open the Actor page on Apify Store and click Start Actor.
2. Describe the image you want in prompt.
3. Optionally pick an aspect ratio (defaults to 1:1).
4. Run the Actor and get imageUrl, savedImageKey, and imageBase64 from the dataset.

Connect via API

cURL:

curl -X POST "https://api.apify.com/v2/acts/akash9078/ai-image-generator/runs" \
-H "Authorization: Bearer YOUR_API_TOKEN" \
-H "Content-Type: application/json" \
-d '{"prompt":"A beautiful sunset over mountains with vibrant orange and purple colors","ratio":"16:9"}'

Python:

import requests

response = requests.post(
    "https://api.apify.com/v2/acts/akash9078/ai-image-generator/runs",
    headers={"Authorization": "Bearer YOUR_API_TOKEN"},

)
print(response.json())

Node.js with the Apify Client:

const { ApifyClient } = require('apify-client');

const client = new ApifyClient({ token: process.env.APIFY_TOKEN });

const run = await client.actor('akash9078/ai-image-generator').call({
    prompt: 'A beautiful sunset over mountains with vibrant orange and purple colors',
    ratio: '16:9',
});

const { items } = await client.dataset(run.defaultDatasetId).listItems();
console.log(items);

AI Image Generator Pricing

Event	Description	Price
imageGenerated	Successfully generated one AI image	$0.001

You only pay for successful image generations. No charges for failed runs.

Why Use the AI Image Generator?

• Prompt-only interface — no model configuration, negative prompts, or sampler tuning required
• 11 aspect ratios out of the box — from square posts to ultra-wide panoramas
• $0.001 per image — pay per event only when an image is actually generated
• Managed infrastructure — NVIDIA's AI infrastructure handles the GPU workload; you just call the API
• Automation-ready — generate images in bulk through the Apify API, schedules, or integrations

Limitations

• A non-empty prompt is required for every run
• Aspect ratio is limited to the 11 supported values listed above
• Output resolution is optimized per ratio and ranges from 672px to 1568px
• Images are delivered through the dataset and Key-Value Store rather than direct streaming

FAQ

Which model powers the image generation?

NVIDIA's Flux 2 Klein model, running on NVIDIA's AI infrastructure.

How much does one image cost?

$0.001 per successfully generated image. Failed runs are not charged.

Can I control the image size?

You control it through the aspect ratio. Each of the 11 ratios has fixed optimized dimensions between 672px and 1568px.

Where do I get the generated image?

From the dataset: imageUrl (public URL), savedImageKey (key-value store), or imageBase64 (inline data for local development).

Can I use it for social media posts?

Yes — the 1:1 (1024x1024) and 9:16 ratios are designed for social posts and stories.
