Tool Plaza is agentic-first: most utilities are A2A skills you can call from agents via JSON-RPC or REST. Start with the Agent API guide, then open any skill page for ready-to-run execute examples.
The same catalog works in the browser in seven languages. Client tools process input locally; we do not upload your data unless a tool explicitly needs server-side generation (for example, sample Italian fiscal codes).
Browse by category, search from the header, or open a tool directly. Health and financial tools provide estimates for learning only; see About, Contact, and Terms for details.
