}'Kunavo vs calling Google directly
Same Nano Banana Pro weights, same responses. What a gateway changes is the account, the SDK and the bill — here is the honest side-by-side.
| Kunavo | Google direct | |
|---|---|---|
| Price (per image) | $0.067+ (−50%) | $0.13 |
| Account | One Kunavo account, key in 2 minutes, $5 minimum top-up | A Google account plus its own billing setup |
| SDK | Keep the OpenAI SDK — change base_url, set model to "nano-banana-pro" | Google's SDK, or their OpenAI-compatible layer where offered |
| Same key also reaches | Claude, Gemini, GPT, image, video and audio models | Google's own catalog only |
| Billing | One Stripe balance, pay-as-you-go, never expires; failed requests unbilled | A separate invoice per provider |
| Rate limits | Shared gateway capacity, no contractual per-account limit | Google's own tier limits, raised by usage history or contract |
Go direct to Google when you need a contractual rate limit, an enterprise SLA, or a provider-only feature on day one. Use Kunavo when you want one key, one bill and a lower per-token rate across every provider.
FAQ
How much does Nano Banana Pro cost?
On Kunavo, Nano Banana Pro is $0.067+ per image — about 50% under Google's official price. Failed requests are never billed, and it's pay-as-you-go — you only pay for successful calls.
Can I call Nano Banana Pro with the OpenAI SDK?
Yes. Set base_url to https://api.kunavo.com/v1, pass your Kunavo key, and set model to "nano-banana-pro". Requests and responses are OpenAI-compatible.
What endpoint does Nano Banana Pro use?
Nano Banana Pro is called via POST /v1/images/generations on Kunavo's OpenAI-compatible API.
What is different from calling Google directly?
The model is the same, at about 50% under Google's list price. What changes is around it: one key and one Stripe balance instead of a Google account with its own billing, the OpenAI SDK with base_url swapped instead of a provider-specific SDK, and the same key also reaching Claude, Gemini, GPT, image, video and audio models. The tradeoff is that gateway capacity is shared — if you need a contractual rate limit or an enterprise SLA on Nano Banana Pro specifically, go direct to Google.
Is Nano Banana Pro cheaper on Kunavo?
Yes — Nano Banana Pro is about 50% under Google's official list price on Kunavo, with no subscription and no minimum monthly spend. You pay per token from a $5 top-up, failed requests are never billed, and the balance never expires.
