# Exa Install & Auth ## Overview Install the official Exa SDK and configure API key authentication. Exa is a neural search API at `api.exa.ai` that retrieves web content using semantic similarity. Authentication uses the `x-api-key` header. The SDK is `exa-js` on npm or `exa-py` on PyPI. ## Prerequisites - Node.js 18+ or Python 3.10+ - Package manager (npm, pnpm, yarn, or pip) - Exa account at [dashboard.exa.ai](https://dashboard.exa.ai) - API key from the Exa dashboard ## Instructions ### Step 1: Install the SDK **Node.js (exa-js)** ```bash set -euo pipefail npm install exa-js # or pnpm add exa-js ``` **Python (exa-py)** ```bash pip install exa-py ``` ### Step 2: Configure the API Key ```bash # Set environment variable export EXA_API_KEY="your-api-key-here" # Or create .env file (add .env to .gitignore first) echo 'EXA_API_KEY=your-api-key-here' >> .env ``` Add to `.gitignore`: ``` .env .env.local .env.*.local ``` ### Step 3: Initialize the Client **TypeScript** ```typescript import Exa from "exa-js"; const exa = new Exa(process.env.EXA_API_KEY); ``` **Python** ```python from exa_py import Exa import os exa = Exa(api_key=os.environ["EXA_API_KEY"]) ``` ### Step 4: Verify Connection ```typescript import Exa from "exa-js"; const exa = new Exa(process.env.EXA_API_KEY); async function verifyConnection() { try { const result = await exa.search("test connectivity", { numResults: 1 }); console.log("Connected. Results:", result.results.length); console...
