Nano Banana API: What the text step costs
Our uncensored api charges strictly by token volume, so you can calculate exact costs for your text pipeline without hidden fees or subscription traps.
No subscription. Prepaid credit never expires.

Worked examples
Script generation for 50 short videos
Generating a 2,000-token script for each of 50 videos requires 100,000 input tokens and 100,000 output tokens. Input cost: 0.1 * 0.25 = $0.025. Output cost: 0.1 * 1.00 = $0.10. Total: $0.125.
Captioning and metadata for a photo dataset
Processing 1,000 images with 500 input tokens and 150 output tokens each results in 500,000 input tokens and 150,000 output tokens. Input cost: 0.5 * 0.25 = $0.125. Output cost: 0.15 * 1.00 = $0.15. Total: $0.275.
Post-processing extraction from a long transcript
Analyzing a 50,000-token transcript to extract key points requires 50,000 input tokens and 2,000 output tokens. Input cost: 0.05 * 0.25 = $0.0125. Output cost: 0.002 * 1.00 = $0.002. Total: $0.0145.
Simple Token Pricing
The nano banana api uses a transparent, usage-based model. You pay $0.25 per million input tokens and $1.00 per million output tokens. This structure ensures that you only pay for the actual text processing your pipeline requires, whether you are generating scripts, captions, or metadata for media assets.
There are no monthly fees, no minimum commitments, and no hidden charges for streaming or tool calling. The open-weight model is tuned for uncensored creative workflows, meaning you do not pay extra for flexibility in content type. You can load prepaid credit and watch your balance decrease precisely as your tokens are consumed.
Prepaid Credits & Bonuses
We offer a straightforward prepaid credit system starting at $10. To reward heavier usage, we provide bonus credit on top-ups: you receive a +5% bonus when you add $50 or more, and a +10% bonus when you add $100 or more. This means your effective cost per token decreases as you scale your pipeline, without locking you into a rigid subscription tier.
Top-ups can be completed using crypto (USDT or USDC). The credit is applied immediately to your account, allowing your API requests to proceed without interruption. This pay-as-you-go approach is ideal for developers who want to maintain precise control over their operational expenses.
No Expiration
Once you purchase prepaid credit, it never expires. You can top up whenever you need more capacity, and the balance will remain available for future projects. This is particularly useful for long-running pipelines or seasonal content campaigns where usage might fluctuate.
Unlike some services that charge for idle time or reset unused quotas monthly, our uncensored api ensures that your investment in credit is preserved until you are ready to use it. You can regenerate your API key at any time without losing your remaining balance, giving you full security control over your account.

Questions and answers
Does the API charge for streaming responses?
No, streaming responses via SSE are charged at the same token rate as standard responses. You are billed based on the total input and output tokens processed, regardless of how the data is transmitted to your client.
What happens if I exceed my prepaid balance?
Your API requests will be blocked until you add more credit. Since there are no subscriptions, you will not incur unexpected charges or go into debt. You can add funds at any time to resume your pipeline immediately.
Is the trial credit valid for the same model?
Yes, the $0.50 trial credit is valid for the same uncensored large language model used in the paid tier. It is available to new accounts without requiring a card, allowing you to test the text completion capabilities before committing to a purchase.
Can I use the nano banana api for image generation pipelines?
We do not generate images ourselves. Our API provides the text completion layer that powers the prompt writing and post-processing steps for your image generation pipeline. You can use our uncensored api to generate detailed prompts that are then sent to an image generation service.
