The Anthropic API (Claude API) lets developers build Claude into their products and tools: Opus (most capable), Sonnet (balanced, the coding favourite) and Haiku (fast and cheap). It supports very long context, image and PDF understanding, tool use, web search, code execution, prompt caching and batch processing — widely used for AI coding (Claude Code, Cursor, Cline, OpenClaw), support bots, document analysis and agents.
① Suitable for machine learning, OpenClaw and more.
② Open the Anthropic API website (Claude Developer Platform), sign in, switch organisation and generate a key.
③ Call the API following the official docs.
Prices shown are for display only: please confirm the final quote with the AIFUNS team before paying. Company bank transfers and invoices are available.
