Nano Banana 2 API on Wireflow

Nano Banana 2 brings Pro-level image quality at Flash speed, generating photorealistic images with accurate text rendering and native 4K resolution. Through Wireflow's REST API, you can integrate Nano Banana 2 into any application with a single HTTP call. No Google SDK setup required.

The API supports text-to-image generation across 14+ aspect ratios, multi-image editing with up to 14 reference inputs, and search-grounded generation that reduces visual hallucination. Wireflow adds batch execution, webhook triggers, and idempotency keys on top, so you can run Nano Banana 2 at production scale without building infrastructure.

Nano Banana 2 API Capabilities

๐Ÿ–ผ๏ธ

Native 4K Image Output

Generate images at 1K, 2K, or 4K resolution natively without upscaling. 4K renders complete in under 20 seconds.

โšก

Sub-6 Second Generation

Nano Banana 2 produces 1K images in 4 to 6 seconds, matching Flash-tier speed with Pro-level visual quality.

๐Ÿ”ค

Accurate Text Rendering

Render legible text in multiple languages directly in generated images. Useful for ads, social media graphics, and signage.

๐Ÿ“

14+ Aspect Ratios

Support for 1:1, 16:9, 9:16, 4:3, 21:9, and more. Covers every format from Instagram stories to ultrawide banners.

๐Ÿ”—

Webhook and Batch Execution

Trigger generations from external systems via webhooks without API keys. Run batch jobs with idempotency guarantees.

๐Ÿงฉ

Chain with Other Models

Pipe Nano Banana 2 output into upscalers, background removers, or video generators inside a single workflow execution.

More Than Just Nano Banana 2 API

Pro Quality at Flash Speed

Nano Banana 2 matches the visual fidelity of Nano Banana Pro while generating images 3x faster. Explore the Nano Banana 2 model page for benchmark comparisons and sample outputs.

Pro Quality at Flash Speed

Simple REST Integration

Call the API with curl, fetch, or any HTTP client. No SDK installation or Google Cloud credentials needed. See the Nano Banana API integration guide for working code examples.

Simple REST Integration

Batch Processing at Scale

Submit hundreds of prompts in parallel with idempotency keys that prevent duplicate executions. Learn how batch image generation via API works for high-volume production use cases.

Batch Processing at Scale

Multi-Model Pipelines

Chain Nano Banana 2 with Kling video generation or Crystal Upscaler in one execution. The Flux 2 API code examples show the same pattern applied to another model.

FAQs

What is the Nano Banana 2 API?
Nano Banana 2 is Google DeepMind's latest image generation model built on Gemini 3.1 Flash Image. Wireflow provides REST API access to run it without setting up Google Cloud credentials or SDKs.
How fast does Nano Banana 2 generate images?
At 1K resolution, Nano Banana 2 generates images in 4 to 6 seconds. At native 4K resolution, generation completes in under 20 seconds without requiring a separate upscaling step.
What resolutions does Nano Banana 2 support?
Nano Banana 2 supports native 1K, 2K, and 4K output. It also handles 14+ aspect ratios including 1:1, 16:9, 9:16, 4:3, 3:2, 21:9, and ultra-tall formats like 1:4.
How does Nano Banana 2 compare to Nano Banana Pro?
Nano Banana 2 delivers comparable visual quality to Pro at roughly half the cost and 3x the speed. Pro remains the choice for maximum fidelity when latency is not a concern.
Can I run Nano Banana 2 in batch mode?
Yes. Wireflow's execute endpoint supports parallel batch requests with idempotency keys. You can submit hundreds of prompts and poll each execution independently for results.
Does the API require Google Cloud credentials?
No. Wireflow handles the model hosting. You authenticate with a Wireflow API key (Bearer sk-...) and call standard REST endpoints. No Google SDK or service account setup needed.
What is search-grounded generation in Nano Banana 2?
Search-grounded generation lets Nano Banana 2 reference real-time web information when creating images. This reduces visual hallucination and improves accuracy for prompts that reference real objects or places.
Can I chain Nano Banana 2 with video generation?
Yes. In a Wireflow workflow, you can connect Nano Banana 2 output to Kling or Veo video nodes. The generated image becomes the first frame, and the video model animates it based on a motion prompt.
