1. Web Scraper Extractor API — Intelligent Web Data Collection

What it does: Extracts structured data from any website without parsing HTML yourself. Handles JavaScript rendering, pagination, dynamic content, and returns clean JSON.

Why it matters: Web scraping is one of the most common tasks developers face — competitive analysis, price monitoring, lead generation, market research. Building your own scraper means handling proxies, rotating user agents, dealing with bot detection, managing rate limits, and debugging JavaScript-heavy sites.

Use cases:

• E-commerce price comparison and dynamic pricing analysis
• Real estate listing aggregation for market analysis
• Job board data collection for recruitment platforms
• News and content monitoring across multiple sources

Pricing: Free tier: 100 requests/month | Basic: $9.99/month | Professional: $49.99/month

Code Example — Node.js:

const https = require('https');

const API_KEY = process.env.RAPIDAPI_KEY;
const API_HOST = 'web-scraper-extractor.p.rapidapi.com';

function scrapeWebsite(url) {
  return new Promise((resolve, reject) => {
    const options = {
      hostname: API_HOST,
      path: `/api/scrape?url=${encodeURIComponent(url)}&format=json`,
      method: 'GET',
      headers: {
        'x-rapidapi-key': API_KEY,
        'x-rapidapi-host': API_HOST
      }
    };

    const req = https.request(options, (res) => {
      let data = '';
      res.on('data', (chunk) => { data += chunk; });
      res.on('end', () => {
        try {
          const result = JSON.parse(data);
          resolve(result.data);
        } catch (err) {
          reject(err);
        }
      });
    });
    req.on('error', reject);
    req.end();
  });
}

// Usage
scrapeWebsite('https://example.com/products')
  .then(data => console.log('Scraped data:', data))
  .catch(err => console.error('Scrape error:', err));

Code Example — Python:

import requests
import os

API_KEY = os.environ.get('RAPIDAPI_KEY')
API_HOST = 'web-scraper-extractor.p.rapidapi.com'

def scrape_website(url):
    headers = {
        'x-rapidapi-key': API_KEY,
        'x-rapidapi-host': API_HOST
    }
    params = {'url': url, 'format': 'json'}

    response = requests.get(
        f'https://{API_HOST}/api/scrape',
        headers=headers,
        params=params,
        timeout=30
    )
    response.raise_for_status()
    return response.json().get('data')

data = scrape_website('https://example.com/products')
print(data)

      });
    });
    req.on('error', reject);
    req.end();
  });
}

auditWebsite('https://example.com')
  .then(audit => {
    console.log(`Overall Score: ${audit.overallScore}/100`);
    console.log(`Mobile Friendly: ${audit.mobileFriendly}`);
    console.log(`Recommendations: ${audit.recommendations.length}`);

5. SSL Certificate Checker API — Certificate Validation

Use cases:

• Automated certificate expiration monitoring
• Security audit dashboards
• Domain portfolio health checks
• Infrastructure monitoring

Code Example — Node.js:

const https = require('https');

const API_KEY = process.env.RAPIDAPI_KEY;

  return new Promise((resolve, reject) => {
    const options = {
      hostname: API_HOST,
      path: `/check?domain=${encodeURIComponent(domain)}`,
      method: 'GET',
      headers: {
        'x-rapidapi-key': API_KEY,
        'x-rapidapi-host': API_HOST
      }
    };

    const req = https.request(options, (res) => {
      let data = '';
      res.on('data', (chunk) => { data += chunk; });
      res.on('end', () => resolve(JSON.parse(data)));
    });
    req.on('error', reject);
    req.end();
  });
}

checkSSL('example.com')
  .then(cert => {
    console.log(`Valid: ${cert.isValid}`);
    console.log(`Expires: ${cert.expirationDate}`);
    console.log(`Days remaining: ${cert.daysUntilExpiration}`);
  });
