If you need movie or TV metadata for a side project, content site, or recommendation product, three APIs cover almost every use case at no cost. This shortlist explains where each one fits.
Quick comparison
| API | Best for | Auth | Free tier signal |
|---|---|---|---|
| TMDB | Posters, trending, discovery | API key | Limited |
| OMDb | IMDb-style lookup by ID or title | API key | Limited |
| TVmaze | TV shows, episodes, schedules | None | Free |
What "free" actually means here
For a movie/TV API to qualify:
- It must allow a real product (not just a demo) on the free tier.
- It must publish documented endpoints, not just a listing on a website.
- The auth model must be reasonable — at most a free developer key.
All three APIs on this list pass that bar; the differences are in coverage and integration model.
API options
TMDB API
TMDB API is the de-facto choice for movie discovery. It has the richest poster and backdrop coverage, well-maintained trending and discovery endpoints, and a clean v3 REST API plus newer v4 features.
Use it when:
- You are building a movie discovery, recommendation, or browse app.
- You want high-quality posters, backdrops, and people images.
- You need trending or popular lists that update daily.
Integration complexity is medium — you need a free key, you need to handle image URL composition, and the response shapes are detailed but well-documented.
OMDb API
OMDb API is a lightweight community service that exposes IMDb-style metadata. It is a single-endpoint REST API with simple title or IMDb-ID lookup.
Use it when:
- You only need quick metadata lookup (title, year, rating, poster).
- You are integrating IMDb IDs from another data source.
- You want the simplest possible movie API.
The free tier is limited to a small daily request count — fine for hobby projects, not for production scale.
TVmaze API
TVmaze is purpose-built for TV. It exposes shows, episodes, cast, broadcast schedules, and search, all without an API key.
Use it when:
- You are building a TV-focused product (tracker, schedule, episode reminder).
- You want broadcast schedule data.
- You don't want to manage API keys.
For movies, TVmaze does not apply — it is TV-only by design.
Picking the right one
Match the API to the product:
- Movie discovery, browsing, posters → TMDB.
- Quick movie lookup, IMDb-ID-based → OMDb.
- TV shows, episodes, schedules → TVmaze.
Most production apps end up combining TMDB for movies with TVmaze for TV. OMDb is usually a fallback or a lightweight option for prototypes.
When not to use these APIs
These APIs are excellent free options, but they are not the right fit when you need:
- Streaming availability data. None of these track which streaming service has which title in your country. For that, look at services like JustWatch (paid) or Watchmode.
- Box office or ticket data. Movie metadata is here; commercial box-office data is not.
- Rights to use posters or images commercially without attribution. Always read the licensing terms before shipping a commercial product that displays third-party imagery at scale.

Frequently Asked Questions
›Which movie API does not require an API key?
TVmaze is the only fully keyless option in this list. TMDB and OMDb both require a free developer key.
›What is the best API for movie posters and trending content?
TMDB has the best poster and backdrop coverage and well-maintained trending and discovery endpoints, which is why most movie-discovery apps use it as their primary source.
›Is OMDb the same as IMDb?
OMDb is a community-built API that exposes IMDb-style metadata via a simpler interface. It is not the official IMDb API (IMDb does not offer a public API), but it works for ID-based or title-based lookups.
›Which API is best for TV schedules and episode tracking?
TVmaze is purpose-built for TV — it covers shows, episodes, cast, and broadcast schedules, all without an API key.
