# Perplexity Install & Auth ## Overview Set up Perplexity Sonar API access using the OpenAI-compatible chat completions endpoint at `https://api.perplexity.ai`. Perplexity does not have a custom SDK -- you use the standard OpenAI client library pointed at Perplexity's base URL. ## Prerequisites - Node.js 18+ or Python 3.10+ - Perplexity account at [perplexity.ai](https://www.perplexity.ai) - API key from [perplexity.ai/settings/api](https://www.perplexity.ai/settings/api) ## Instructions ### Step 1: Install OpenAI Client Library ```bash set -euo pipefail # Node.js / TypeScript npm install openai # Python pip install openai ``` There is no `@perplexity/sdk` package. Perplexity uses the OpenAI wire format, so you use the official `openai` package with a custom `baseURL`. ### Step 2: Configure API Key ```bash # Set environment variable export PERPLEXITY_API_KEY="pplx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" # Or create .env file (add .env to .gitignore) echo 'PERPLEXITY_API_KEY=pplx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' >> .env ``` API keys start with `pplx-` and are generated at [perplexity.ai/settings/api](https://www.perplexity.ai/settings/api). You must add credits to your account before making API calls. ### Step 3: Verify Connection (TypeScript) ```typescript import OpenAI from "openai"; const client = new OpenAI({ apiKey: process.env.PERPLEXITY_API_KEY, baseURL: "https://api.perplexity.ai", }); async function verify() { const respons...
