Authentication

API Keys

All API requests require authentication using an API key. You can create and manage your API keys in the Settings > API Keys page.

Subscription Required

API access is only available for users with an active subscription (Standard or Pro plan).

Creating an API Key

Navigate to Settings > API Keys
Click Create Key
Enter a descriptive name for your key (e.g., "Production", "Development")
Copy and securely store your API key

Important

Your API key will only be shown once when created. Store it securely - you won't be able to see it again.

Using Your API Key

Include your API key in the Authorization header of every request:

Authorization: Bearer sk-your-api-key

Example Request

curl -X POST https://nano-banana-pro.net/api/ai/nano-banana/generate \
  -H "Authorization: Bearer sk-your-api-key" \
  -H "Content-Type: application/json" \
  -d '{"prompt": "a cute cat"}'

const response = await fetch('https://nano-banana-pro.net/api/ai/nano-banana/generate', {
  method: 'POST',
  headers: {
    'Authorization': 'Bearer sk-your-api-key',
    'Content-Type': 'application/json',
  },
  body: JSON.stringify({ prompt: 'a cute cat' }),
});

import requests

response = requests.post(
    'https://nano-banana-pro.net/api/ai/nano-banana/generate',
    headers={
        'Authorization': 'Bearer sk-your-api-key',
        'Content-Type': 'application/json',
    },
    json={'prompt': 'a cute cat'}
)

API Key Limits

Maximum 5 API keys per user
Keys do not expire automatically
You can delete keys at any time from the settings page

Security Best Practices

Never expose your API key

Do not include your API key in client-side code, public repositories, or anywhere it could be accessed by others.

Use environment variables

Store your API key in environment variables rather than hardcoding it:

# .env file
NB_PRO_API_KEY=sk-your-api-key

// Usage
const apiKey = process.env.NB_PRO_API_KEY;

Rotate keys regularly

If you suspect your key has been compromised, delete it immediately and create a new one.

Use separate keys for different environments

Create separate API keys for development, staging, and production environments.
