LurkAPI returns public social media data as JSON: creator profiles, posts, comments, video transcripts and ad library results across 16 platforms, including TikTok, Instagram, YouTube, Reddit and X. Code samples come in six languages, with an OpenAPI spec and a live playground on every docs page. The same endpoints work as an MCP server in Claude, ChatGPT and Cursor. Most calls cost 1 credit; the first 100 are free, no card.
