Access Google Bard via API

Yesterday, I was trying to access Bard API via Rust

The task is WIP because :

1. I’m still learning Rust (Although on Day 5 I was able to access a URL from rust code)
2. I didn’t know how to access Bard API

It started with a Youtube video that:

• Uses python code which uses Bard library
  • Not sure if it is official one or third party one
  • In either case it won’t be directly useful in rust code
• Uses a hack to get session cookie from browser (which will expire sooner or later)

At that time, I didn’t know whether Google has made Bard API accessible via an API

Turns out, they have!

There used to be a waitlist - that URL is now 404

Instead https://makersuite.google.com/ takes you to https://makersuite.google.com/app/prompts/new_freeform

On the left panel, first item is Get the API Key

Select Develop in your own environment (Assuming you are doing this for personal project like myself)

Needless to say, copy the key and keep it safe.¹

They’ve listed the following as a sample. (Add your API key after key=)

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

Enjoy!
