Exa Hello World

Overview

Minimal working examples demonstrating all core Exa search operations: basic search, search with contents, find similar, and get contents. Each example is runnable standalone.

Prerequisites

• exa-js SDK installed (npm install exa-js)
• EXA_API_KEY environment variable set
• Node.js 18+ with ES module support

Instructions

Step 1: Basic Search (Metadata Only)

import Exa from "exa-js";

const exa = new Exa(process.env.EXA_API_KEY);

// Basic search returns URLs, titles, and scores — no page content
const results = await exa.search("best practices for building RAG pipelines", {
  type: "auto",       // auto | neural | keyword | fast | instant
  numResults: 5,
});

for (const r of results.results) {
  console.log(`[${r.score.toFixed(2)}] ${r.title}`);
  console.log(`  ${r.url}`);
}

Step 2: Search with Contents

// searchAndContents returns text, highlights, and/or summary with each result
const results = await exa.searchAndContents(
  ,
  {
    : ,
    : ,
    : { :  },
    : { : , :  },
    : { :  },
  }
);

 ( r  results.) {
  .();
  .();
  .();
  .();

  .();
