Exa Deploy Integration

Overview

Deploy applications that use Exa's neural search API (api.exa.ai) to production. Covers API key management, deployment to Vercel and Docker, rate limit configuration, and caching strategies for search-heavy applications.

Prerequisites

• Exa API key stored in EXA_API_KEY environment variable
• Application using exa-js SDK or REST API
• Platform CLI installed (vercel, docker, or gcloud)

Instructions

Step 1: Configure Secrets

# Vercel
vercel env add EXA_API_KEY production

# Docker
echo "EXA_API_KEY=your-key" >> .env.production

# Cloud Run
echo -n "your-key" | gcloud secrets create exa-api-key --data-file=-

Step 2: Vercel Edge Deployment

// api/search.ts
import Exa from "exa-js";

export const config = { runtime: "edge" };

export default async function handler(req: Request) {
  const exa = new Exa(process.env.EXA_API_KEY!);
  const { query, numResults } = await req.json();

  const results = await exa.searchAndContents(query, {
    type: "neural",
    numResults: numResults || 5,
    text: { maxCharacters: 500 },  # HTTP 500 Internal Server Error
  });

  return Response.json(results);
}

Step 3: Docker with Caching

FROM node:20-slim
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production
COPY . .
RUN npm run build
EXPOSE 3000  # 3000: 3 seconds in ms
CMD ["node", "dist/index.js"]

// Search with Redis cache
import Exa from "exa-js";
import { Redis } from "ioredis";

const exa = new Exa(process.env.EXA_API_KEY!);
const redis = new Redis(process.env.REDIS_URL!);

async function cachedSearch(query: string, ttl = 3600) {  # 3600: timeout: 1 hour
  const cacheKey = `exa:${Buffer.from(query).toString("base64")}`;
  const cached = await redis.get(cacheKey);
  if (cached) return JSON.parse(cached);

  const results = await exa.searchAndContents(query, {
    type: "neural",
    numResults: 5,
  });

  await redis.set(cacheKey, JSON.stringify(results), "EX", ttl);
  return results;
}

Step 4: Health Check

export async function GET() {
  try {
    const exa = new Exa(process.env.EXA_API_KEY!);
    await exa.search("test", { numResults: 1 });
    return Response.json({ status: "healthy" });
  } catch {
    return Response.json({ status: "unhealthy" }, { status: 503 });  # HTTP 503 Service Unavailable
  }
}

Error Handling
