Find recent sources with key excerpts using Exa search

What you get

A TypeScript snippet that runs an Exa search and returns each result's title, URL and the most relevant excerpts, ready to pass to an LLM.

Prerequisites

Node.js 18+
An Exa API key from https://dashboard.exa.ai/api-keys

Steps

Install the SDK:

Shell

npm install exa-js

Set your key (the SDK reads it automatically):

Shell

export EXA_API_KEY="your-api-key"

Basic search with highlights (search.mjs):

JavaScript

import Exa from "exa-js";

const exa = new Exa();

const { results } = await exa.search(
  "best blog posts about vector databases",
  { contents: { highlights: true } },
);

for (const result of results) {
  console.log(result.title, result.url);
}

Narrow it down with filters and page text when you need more context:

TypeScript

import Exa from "exa-js";

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

const response = await exa.search("AI startups 2024", {
  type: "auto",
  numResults: 10,
  includeDomains: ["crunchbase.com"],
  startPublishedDate: "2024-01-01",
  contents: {
    text: { maxCharacters: 1000, verbosity: "compact" },
    highlights: true
  }
});

Test it

Shell

node search.mjs

You should see a list of titles and URLs. Each result object also carries highlights (and text when requested).
