Image Generation API Without the Complexity

Most image generation APIs force you to manage model selection, parameter tuning, and result handling through raw HTTP calls. Wireflow wraps those steps into a drag-and-drop canvas where each model is a node you connect visually. The same pipeline runs headlessly via REST, so your production code stays clean while you iterate on the canvas.

Whether you need photorealistic product shots, stylized illustrations, or batch processing across model variants, the visual approach cuts integration time from days to minutes. Every node supports webhooks, spend limits, and per-user metering out of the box.

What You Can Build

🖼️

Multi-Model Image Pipelines

Chain text-to-image, upscaling, and style transfer models in a single workflow that runs via API.

🔑

Single API Key Access

Access Flux, Recraft, Nano Banana, and other top models through one unified API key and billing account.

📊

Per-User Spend Controls

Set generation limits per API consumer so downstream apps never exceed their allocated budget.

⚡

Webhook Callbacks

Get notified when each generation step completes instead of polling endpoints repeatedly.

🔄

Batch Processing

Submit arrays of prompts and receive results asynchronously with progress tracking per item.

🎨

Visual Prompt Testing

Test prompts and model parameters on the canvas before committing them to your production API calls.

More Than Just Leonardo AI API

Multiple Models, One Endpoint

Switch between Flux, Recraft, and Nano Banana without changing your client code. Wireflow's AI image generator abstracts model routing behind a single REST call.

FAQs

What is the Leonardo AI API used for?
The Leonardo AI API lets developers generate images programmatically using text prompts. It supports multiple models for different styles, from photorealistic portraits to stylized illustrations, and handles requests via standard REST endpoints.
How does Wireflow compare to Leonardo AI API?
Wireflow provides a visual canvas for building multi-step image pipelines that also run headlessly via REST API. Unlike raw API endpoints, you can chain models, add upscaling, and set spend limits per user without writing orchestration code.
Can I switch between image generation models?
Yes. Wireflow supports Flux 2 Pro, Recraft V4, Nano Banana 2, and other models. You can swap the generation node in your workflow without changing your API integration code or client-side implementation.
What image generation models are available?
The platform includes Flux 2 Pro for general image generation, Recraft V4 for design and illustration work, Nano Banana 2 for fast photorealistic output, and ClarityAI for 4x upscaling of generated results.
Does the API support batch image generation?
Yes. You can submit multiple prompts in a single API call and track progress per item. Results return asynchronously through webhooks or polling, making it practical for catalog-scale content production.
How does API pricing work for image generation?
Wireflow uses pay-per-generation pricing with no monthly minimums. Each model has a per-call cost that varies by resolution and quality settings. You can set hard spend limits per API key to control costs.
Can I add upscaling or background removal to my pipeline?
Yes. Drag a ClarityAI upscaler or BiRefNet background remover node after your generation step. The full chain runs as one API call, so your client code stays simple while the backend handles multi-step processing.
Is there a free tier or trial for the image API?
Wireflow offers a free tier with limited generations per month so you can test model quality and API integration before committing to a paid plan. No credit card is required to start building workflows.
