KeyAPI is an AI-agent-first unified social media API that gives developers a single REST key to access profiles, posts, videos, comments, analytics and commerce signals from 20+ platforms; it’s built for LLM pipelines, automation and autonomous agents by streaming real-time and historical social data (up to 1,000 days) as clean, AI-ready JSON, removing multi-key and rate-limit complexity so teams can train models, enrich prompts, power agent workflows, and deploy scalable social intelligence faster.
