IMDb Data Extraction
Extract publicly available data from IMDb at scale using AlterLab's API — JavaScript rendering, structured extraction, and automatic retries in one request.
Website Compatibility Notes
IMDb has relatively light bot protections. Most movie and TV show pages serve well-structured HTML without complex challenge systems. IMDb does apply rate limiting for high-frequency requests. Authenticated features (watchlist, ratings) require login, but all public data is accessible without authentication.
Technical Context
IMDb title URLs use a 'tt' prefix followed by digits (e.g., /title/tt0111161/). Person pages use 'nm' prefix. IMDb's API (for affiliates) provides some data, but the web pages contain additional details like full cast lists, technical specs, and trivia. IMDb is owned by Amazon and shares some infrastructure, but the bot protections are significantly lighter than Amazon's retail sites.
