The Problem

Every developer needs fake data for testing. You install Faker.js, write a script, generate JSON, paste it somewhere. Repeat for every project.

What if you could just call a REST API and get realistic test data instantly?

The Solution: Random Data API on RapidAPI

I built a free REST API that generates realistic fake data — names, emails, addresses, companies, phone numbers — powered by Faker.js running on Cloudflare Workers (sub-50ms globally).

Quick Example 

curl -X GET "https://random-data-api.p.rapidapi.com/person" \
  -H "X-RapidAPI-Key: YOUR_KEY" \
  -H "X-RapidAPI-Host: random-data-api.p.rapidapi.com"
Enter fullscreen mode Exit fullscreen mode

Response:

{
  "name": "John Smith",
  "email": "john.smith@example.com",
  "address": "1234 Oak Street, Springfield, IL 62704",
  "phone": "+1-555-0123",
  "company": "Acme Corp",
  "jobTitle": "Senior Developer"
}
Enter fullscreen mode Exit fullscreen mode

Bulk Generation

Need 100 users for your database seed?

curl -X GET "https://random-data-api.p.rapidapi.com/persons?count=100"
Enter fullscreen mode Exit fullscreen mode

Supported Data Types

Endpoint Generates
/person Name, email, phone, address
/company Company name, industry, catchphrase
/address Street, city, state, zip, coordinates
/finance Credit card, IBAN, BIC, currency
/internet Username, avatar URL, IP, user agent

Localization

Supports 20+ locales: ?locale=ja for Japanese, ?locale=de for German, etc.

Why Use an API Instead of npm?

  1. No install — works from any language (Python, Go, Ruby, not just JS)
  2. No build step — call from Postman, curl, or your CI pipeline
  3. Consistent — same version across all team members
  4. Serverless-friendly — no bundling Faker.js (400KB+) into your Lambda

Free Tier

  • 200 requests/month (no credit card)
  • Sub-50ms response times (Cloudflare edge)
  • Rate limit: 5 req/sec
