Add Rotten Tomatoes Ratings to Your App with a Single API Call

Building a movie recommendation engine? A watchlist app? Or maybe just a weekend project that helps you decide what to watch on Friday night? You're going to need ratings data — and Rotten Tomatoes is the gold standard for aggregated critic and audience scores.

The Rotten Tomatoes Ratings API gives you instant access to movie and TV show ratings through a simple REST endpoint. No scraping, no browser automation, no headaches. Just send a query and get structured data back.

What It Does

This API lets you search for any movie or TV show by title and returns Rotten Tomatoes rating data — including critic scores, audience scores, and metadata. It's perfect for:

• Movie recommendation apps that rank content by critical reception
• Watchlist tools that display ratings alongside your saved titles
• Data dashboards comparing ratings across studios, genres, or time periods
• Discord/Slack bots that respond to "is this movie any good?"

Quick Start

Here's how to fetch ratings for any title using JavaScript:

const response = await fetch(
  'https://espn-scores-consolidated-production.up.railway.app/api/search?query=Oppenheimer',
  {
    method: 'GET',
    headers: {
      'X-RapidAPI-Key': 'YOUR_RAPIDAPI_KEY',
      'X-RapidAPI-Host': 'rotten-tomatoes-ratings.p.rapidapi.com'
    }
  }
);

const data = await response.json();
console.log(data);

Swap out Oppenheimer for any movie or show title. The API handles fuzzy matching, so partial titles and common misspellings still return relevant results.

Real-World Use Case: Movie Night Picker

Imagine building a "Movie Night" app where users add candidate films and the group votes. You could enrich each suggestion with Rotten Tomatoes scores automatically:

const movies = ['Dune Part Two', 'The Batman', 'Everything Everywhere All at Once'];

const enriched = await Promise.all(
  movies.map(async (title) => {
    const res = await fetch(
      `https://espn-scores-consolidated-production.up.railway.app/api/search?query=${encodeURIComponent(title)}`,
      {
        headers: {
          'X-RapidAPI-Key': 'YOUR_RAPIDAPI_KEY',
          'X-RapidAPI-Host': 'rotten-tomatoes-ratings.p.rapidapi.com'
        }
      }
    );
    return res.json();
  })
);

console.log(enriched);

Now every suggestion comes with credible rating data that helps the group decide.
