Exa Security Basics

Overview

Security best practices for Exa API integrations. Exa authenticates via the x-api-key header. Key security concerns include API key protection, content moderation for search results, domain filtering to prevent exposure to malicious sources, and query sanitization.

Prerequisites

• Exa API key from dashboard.exa.ai
• Understanding of environment variable management
• .gitignore configured for secrets

Instructions

Step 1: API Key Management

# .env (NEVER commit to git)
EXA_API_KEY=your-api-key-here

# .gitignore — add these entries
.env
.env.local
.env.*.local

// Validate API key exists before creating client
import Exa from "exa-js";

function createSecureClient(): Exa {
  const apiKey = process.env.EXA_API_KEY;
  if (!apiKey) {
    throw new Error("EXA_API_KEY not configured");
  }
  if (apiKey.startsWith("sk_") && apiKey.length < 20) {
    throw new Error("EXA_API_KEY appears malformed");
  }
  return new Exa(apiKey);
}

Step 2: Enable Content Moderation

const exa =  (process..);


 results =  exa.(
  ,
  {
    : ,
    : ,
    : ,  
  }
);
