About Tool Plaza
Tool Plaza is an agentic-first catalog of utility skills published by Ardain Technologies. Call most tools from A2A agents over JSON-RPC or REST, or use the same utilities in the browser—from encoders and validators to health calculators and time helpers.
Our mission
We want useful software to be fast, free, and easy for agents and people. Programmatic skills expose stable helper APIs; matching browser forms stay privacy-friendly. Client tools process input locally and do not upload data unless a tool explicitly requires server-side logic (for example, generating sample fiscal codes). See the Agent API for execute examples.
What you will find
- A2A agent skills — encoders, hashes, validators, converters, and calculators with REST/A2A execute
- Browser tools — the same catalog with forms and guides when you prefer a UI
- Health and fitness — BMI, heart-rate estimates, and related calculators with clear educational context
- Guides on every tool page — each subtool includes an introduction, user guide, and (when programmatic) ready-to-run agent examples
How we build
Tool Plaza is built with Next.js and is designed to scale to a large catalog while keeping each tool isolated and maintainable. We add original documentation and localized descriptions so every page offers meaningful context—not only a form widget.
About the maintainer
Tool Plaza is designed, built, and maintained by Fabrizio Asta.
