Gemini API quickstart

This quickstart shows you how to install your SDK of choice and then make your first Gemini API request.

Install the Gemini API library

Install google.golang.org/genai in your module directory using the go get command:

go get google.golang.org/genai

Make your first request

Get a Gemini API key in Google AI Studio

Use the generateContent method to send a request to the Gemini API.

package main

import (
    "context"
    "fmt"
    "log"

    "google.golang.org/genai"
)

func main() {
    ctx := context.Background()
    client, err := genai.NewClient(ctx, &genai.ClientConfig{
        APIKey:  "YOUR_API_KEY",
        Backend: genai.BackendGeminiAPI,
    })
    if err != nil {
        log.Fatal(err)
    }

    result, err := client.Models.GenerateContent(
        ctx,
        "gemini-2.0-flash",
        genai.Text("Explain how AI works in a few words"),
        nil,
    )
    if err != nil {
        log.Fatal(err)
    }
    fmt.Println(result.Text())
}
