Nano Banana Pro API

gemini-3-pro-image

Nano Banana Pro API exposes Google's Gemini 3 Pro Image model through APINEED for complex graphic design, product mockups, factual visualizations, and controlled image editing.

Google describes Nano Banana Pro as a reasoning-driven image model with Search grounding, thinking, advanced localization, brand consistency, accurate text, and output up to 4K. APINEED uses a non-streaming Chat Completions-compatible route and deliberately omits controls that its adapter does not guarantee.

Nano Banana Pro API capabilities

Nano Banana Pro is the quality-oriented Gemini image option for work where layout, factual grounding, brand treatment, and precise edits matter more than the fastest iteration. [1][2][3]

Reasoned composition

Google says the model uses a default thinking process to refine composition before generation, helping with complex instructions and structured graphics. [1][2]

Text and localization

Official examples focus on legible poster text, diagrams, handwriting styles, and translating designs for different locales. [1]

Grounded production assets

Search grounding and broad world knowledge support factual visualizations, product concepts, and designs based on real-world context. [1][2]

APINEED request boundary

The APINEED V1 route accepts text and API image content blocks but does not expose arbitrary Gemini generation configuration. [3]

Prompts for professional asset production

Specify hierarchy. Describe headline, supporting text, focal object, spacing, and reading order for layouts.

Protect brand details. Name logo placement, product geometry, colors, and elements that must remain unchanged.

Validate factual graphics. Review generated labels and data before publishing even when grounding is used.

Quick Start

Call Nano Banana Pro with the verified APINEED endpoint and model-specific request shape.

1

Create an API key

Store your APINEED key server-side as API_NEED_API_KEY.

export API_NEED_API_KEY=sk-apineed-v1-...
2

Send the request

Use gemini-3-pro-image with POST /v1/chat/completions.

curl https://apineed.com/v1/chat/completions \
  -H "Authorization: Bearer $API_NEED_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "model": "gemini-3-pro-image",
  "messages": [
    {
      "role": "user",
      "content": "A precise editorial product photograph with layered materials, realistic studio light, clean typography, and a balanced magazine composition."
    }
  ],
  "stream": false
}'

Parse the image

Read choices[0].message.content and detect Markdown or raw image data URLs.

const content = response.choices[0].message.content;

Nano Banana Pro API Endpoint

Nano Banana Pro API questions

Practical answers for choosing, integrating, pricing, and operating the Nano Banana Pro API on APINEED.

What is Nano Banana Pro API designed for?

Google positions it for professional asset production and complex visual instructions, including graphic design, high-fidelity product mockups, localized creative, and factual data visualizations. [1][2]

When should I choose Nano Banana Pro over Nano Banana 2?

Choose Pro when precision, complex composition, branding, localization, or grounded information is the priority. Choose Nano Banana 2 when faster iteration and lower-cost general image work are more important. [1][2]

Which endpoint and model ID does APINEED use?

Use gemini-3-pro-image with POST /v1/chat/completions and stream set to false so the complete image response can be parsed consistently. [3]

Can Nano Banana Pro create readable text?

Google specifically highlights poster copy, intricate diagrams, translated designs, and configurable lettering as model strengths, although every production output should still be proofread. [1][2]

Does Nano Banana Pro support grounded generation?

Google documents Search grounding and real-world knowledge in the native model. APINEED V1 does not expose a separate grounding control in this playground. [1][2][3]

Can I submit local reference files here?

Yes. The page uploads local references directly to temporary private object storage, then sends short-lived image_url blocks through APINEED. [3]

How to deploy Nano Banana Pro

Connect Nano Banana Pro to your application through the APINEED media API.

1
