Finds movies or TV shows by title, with optional year and region, and returns release year, poster, overview, and language. Uses TMDB when TMDB_API_KEY is configured (adding movie ratings, popularity, and an optional streaming provider summary) and falls back to no-key Wikidata metadata otherwise. Use it as a movie database API, TV database API, film lookup, title metadata search, or TMDB / Wikidata movie lookup.
