Beat API is a unified API platform that gives AI agents and apps one key for AI models, data, and web tools. Instead of wiring a separate key, documentation, and bill for each provider, an agent searches one catalog, inspects a capability’s inputs and price, and runs it: text, image, and video models including GPT, Claude, Seedance, MiniMax, Veo, Kling, and GPT Image families sit alongside more than 1,000 social data APIs for X, Reddit, TikTok, Instagram, YouTube, and LinkedIn, plus web search, page reading, site maps, and research tools, and reusable workflows for music video and e-commerce video. Agents connect by sending one setup line or through the hosted MCP server, with Claude Code, Codex, Cursor, OpenCode, and other MCP clients supported. Every capability publishes its price before a run, with the BeatAPI rate shown next to the matched public provider rate, and calls spend a prepaid USD balance with one account, one task shape, and hosted output files. Finished image and video tasks return a hosted file URL, and every run keeps its status, usage, files, and failure reasons visible. You can try models in the playground before integrating. It suits indie developers, product teams, and agent builders who want to ship with many models behind a single integration.
