Gemini API quickstart

This quickstart shows you how to get started with the Gemini API using the SDK of your choice.


Prerequisites

This quickstart assumes that you're familiar with running shell scripts.

To complete this quickstart, you must have curl installed in your shell environment.

Set up your API key

To use the Gemini API, you'll need an API key. If you don't already have one, create a key in Google AI Studio.

Get an API key from Google AI Studio

Then, configure your key.

It is strongly recommended that you do not check an API key into your version control system but assign it as an environment variable instead:

export GOOGLE_API_KEY=<YOUR_API_KEY>

Make your first request

Use the generateContent method to generate text.

curl "https://generativelanguage.googleapis.com/v1beta/models/gemini-1.5-flash:generateContent?key=$GOOGLE_API_KEY" \
    -H 'Content-Type: application/json' \
    -X POST \
    -d '{
      "contents": [{
        "parts":[{"text": "Write a story about a magic backpack."}]
        }]
       }' 2> /dev/null
