Gemini 3 Pro Quickstart — API Tutorial and First Request
This Gemini 3 Pro quickstart shows the fastest production path: create one 97AI.PRO API key, call `https://97ai.97claude.com/api/chat`, verify the response, then move the request into your app. Pricing is $3.675 per per million tokens, failed chat completions cost $0, and no Google account is required.
1-minute setup
- Create a 97AI.PRO account and open the API keys page.
- Top up at least $5 by credit card, USDC on Arbitrum, Alipay, or WeChat Pay.
- Copy an API key and call `https://97ai.97claude.com/api/chat` with `model: "chat/gemini-3-pro"`.
- Log the returned credits and balance fields so your production app can show usage clearly.
Copy-ready first request
Run this from a terminal after replacing $YOUR_KEY with your live API key.
curl -X POST https://97ai.97claude.com/api/chat \
-H "Authorization: Bearer $YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"chat/gemini-3-pro","messages":[{"role":"user","content":"Write a short product brief"}]}'
Production checklist
- Store the API key server-side only; never expose it in browser JavaScript.
- Add a request id to your own logs before every chat completion so retries are traceable.
- Handle failed calls as a normal state. 97AI.PRO charges $0 for failures, but your UI should still show the error.
- Keep client timeouts conservative because Gemini 3 Pro returns synchronously.
