perplexity

An unofficial client for the Perplexity AI API.

Installation

Install the gem and add to the application's Gemfile by executing:

$ bundle add perplexity

If bundler is not being used to manage dependencies, install the gem by executing:

$ gem install perplexity

Usage

  1. add your PERPLEXITY_API_KEY to your environment variables (typically in a .env file)
PERPLEXITY_API_KEY=pplx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  1. source the .env file
export $(cat .env)
  1. Interact with perplexity 
messages = [
  {
    role: 'system',
    content: 'Be precise and concise'
  },
  {
    role: 'user',
    content: 'good strategy games for macOS'
  }
]

parameters = {
  model: 'sonar-small-online',
  messages: messages
}

perplexity = Perplexity::API.new(api_key: ENV.fetch('PERPLEXITY_API_KEY'))
response = perplexity.client.chat(parameters: parameters)
  1. Pretty print the response (requires the pp gem)
require 'pp'
pp response
=>
{"id"=>"8db8e4d7-73ef-4313-9f74-3b08cec81139",
 "model"=>"sonar-small-online",
 "created"=>7232621,
 "usage"=>{"prompt_tokens"=>42, "completion_tokens"=>115, "total_tokens"=>157},
