mkdir -p ~/code
cd ~/code
git clone https://github.com/zed-industries/zed

Open Zed Extensions (cmd-shift-x / ctrl-shift-x)
Click "Install Dev Extension"

PERPLEXITY_API_KEY

This extension requires a Perplexity API key to be available via the PERPLEXITY_API_KEY environment variable.

To onbtain a Perplexity.ai API token, login to your Perplexity.ai account and go Settings->API and under "API Keys" click "Generate". This will require you to have Perplexity Pro or to buy API credits. By default the extension uses llama-3.1-sonar-small-128k-online, currently cheapest model available which is roughly half a penny per request + a penny per 50,000 tokens. So most requests will cost less than $0.01 USD.

Take your API key and add it to your environment by adding export PERPLEXITY_API_KEY="pplx-0123456789abcdef..." to your ~/.zshrc or ~/.bashrc. Reload close and reopen your terminal session. Check with env |grep PERPLEXITY_API_KEY.
