What's the Best Movie Database API? IMDb vs TMDb vs OMDb

Movie and TV show data is a valuable resource for developers building entertainment-focused applications. While the Internet Movie Database (IMDb) API has long been a popular choice, alternatives like The Movie Database API(TMDb) and Open Movie Database API(OMDb) offer compelling features that may better suit your project needs. This article compares these two options to help you make an informed decision.

Why Look Beyond IMDb?

We'll start with a pretty bold statement - for the majority of readers, the IMDb API is likely not suited for you, especially if you're a hobbyist developer. The IMDb API is fairly new and popular, but despite its popularity, comes with notable drawbacks:

Cost: The official fee-based service offered through AWS is prohibitively expensive, with costs reaching $150,000 plus additional metered charges. For many developers, especially those working on smaller projects or startups, these expenses are simply untenable.
Terms: IMDb limits data use solely to personal and non-commercial purposes. Additionally, IMDb enforces strict conditions against altering, republishing, reselling, or repurposing data. This severely restricts what you can possibly build.
Architecture: The IMDb API is entirely build on GraphQL. If you are not using this API directly from a client - then integrating the IMDb API into your REST-stack can be challening and add to maintenance costs.
AWS UX: Simply getting access to the IMDb API through AWS Data Exchange can be incredibly confusing if you don't have previous experience. Managing your API usage is likewise challenging.

Given these drawbacks, we strongly recommend considering two popular alternatives - TMDb and OMDb.

Can't I Just Scrape IMDb?

IMDb’s policies also explicitly prohibit web scraping, backed by legal warnings against violating their terms of use. IMDb frequently changes its page layout in order to make scraping difficult and unreliable.

The Movie Database: a Comprehensive Entertainment Database

TMDb (The Movie Database) is a community-driven platform that provides extensive information on movies, TV shows, and celebrities. Its API is designed to cater to both personal and commercial use cases, offering a wide range of data points and features.

TMDb API: Features and Capabilities

The Movie Database API stands out for its comprehensive coverage of the entertainment industry. It offers access to detailed information about movies, TV shows, and actors. The API's advanced search functions allow for precise queries across various categories. High-quality images and videos associated with each entry improve the visual appeal of applications using this data.

One of The Movie Database's strengths is its support for multiple languages, making it an excellent choice for developers targeting a global audience. The API also provides access to user-generated content, such as reviews and lists, adding a layer of community engagement to the data.

Does the TMDb API offer an OpenAPI/Swagger spec?

The TMDb APi is very well documented, including an OpenAPI V3.1 specification.

Accessing and Using the TMDb API

Getting started with TMDb API is straightforward. Follow these steps to get a TMDB API key. Its terms of use differ for commercial and non-commercial applications - so review the latest terms on their website.

Here's a simple example of fetching movie data using TMDB API with Node.js:

const TMDB_API_KEY = 'your_api_key_here';
const movieId = 778;

fetch(`https://api.themoviedb.org/3/movie/${movieId}?api_key=${TMDB_API_KEY}&append_to_response=videos,credits`)
.then(res => res.json())
.then(data => console.log('Movie Data:', data))
.catch(err => console.error('Error: ', err));

For those preferring command-line interactions, here's the equivalent curl command:

curl --request GET \
--url 'https://api.themoviedb.org/3/movie/778?api_key=your_api_key_here&append_to_response=videos,credits'

Note that the 3 in the path indicates the version of the API you are using. The current stable version is v3 but v4 is in progress.

TMDb API: Considerations

While TMDB offers a wealth of data, it's important to note its rate limit of 40 requests per 10 seconds. This generous allowance is suitable for most applications but may require careful management for high-volume use cases. The API is free for non-commercial use, but commercial applications need to negotiate terms directly with TMDB.

Open Movie Database: Focused and User-friendly

The Open Movie Database (OMDb) takes a different approach, offering a streamlined API focused primarily on movie information. Its simplicity and ease of use make it an attractive option for developers working on smaller-scale or movie-centric projects.

OMDb API: Features and Capabilities

The strength of the OMDB API lies in its straightforward approach to movie data. The API allows searches by title, IMDb ID, type, or year, making it easy to find specific entries. Users can choose between short or full plot summaries, catering to different depth requirements. The API supports both JSON and XML response formats, offering flexibility in data handling.

The API also offers movie posters, however access is gated to patrons only.

Does the OMDb API offer an OpenAPI/Swagger Spec?

The OMDb API does offer an OpenAPI 2.0 / Swagger specification, but many modern tools do not support Swagger anymore. We decided to create an upgraded OpenAPI 3.0 specification.

Accessing and Using the OMDb API

Accessing the OMDB API requires a simple sign-up process on their website, followed by a minimum $1 monthly donation via Patreon. Once you receive your API key, you're ready to start making requests.

Here's an example of how to fetch movie data using the OMDB API with Node.js:

const fetch = require('node-fetch');
const OMDB_API_KEY = 'your_api_key_here';
const title = 'Interstellar';

fetch(`https://www.omdbapi.com/?apikey=${OMDB_API_KEY}&t=${title}&plot=short&r=json`)
.then(res => res.json())
.then(data => console.log('Movie Data:', data))
.catch(err => console.error('Error: ', err));

And here's the equivalent curl command:

curl --get \
'https://www.omdbapi.com/?apikey=your_api_key_here&t=Interstellar&plot=short&r=json'

The existing documentation is a bit bare, so we created a Zudoku API docs page to help you explore the API

OMDb API: Considerations

The OMDB pricing model is transparent and accessible, requiring only a small monthly donation to remove the free tier's 1000 calls / day rate limit. However, the API has some limitations. It focuses primarily on movies, with limited TV show information. The exact rate limits for paid members aren't publicly disclosed, which may be a concern for applications with unpredictable traffic patterns.

Choosing between TMDb and OMDb

Your choice between TMDb and OMDb should be guided by your project's specific needs. TMDb is ideal for applications requiring comprehensive entertainment data, including TV shows, images, and multilingual support. Its extensive feature set makes it suitable for intricate, data-rich applications.

OMDB shines in its simplicity and focus. If your project revolves around movies and doesn't require extensive TV show or celebrity information, the straightforward API and pricing model might be the perfect fit.

Consider factors such as the scope of your data needs, your budget, and the scale of your app. TMDB offers a free non-commercial tier and negotiable commercial terms for flexibility, while the low-cost model is attractive for smaller projects or those just starting out. In general, TMDb seems like a better documented and more reliable service with active development, while OMDb is primarily a one-man operation.

Both APIs provide valuable alternatives to the IMDb API, each with its own strengths. By evaluating your project requirements against the features and limitations of each API, you can select the option that best aligns with your development goals and user needs.
