A proof of concept, offered as it is

Effective 18 September 2026 · calendar.aithos.world

1. What the service is

The A2A Calendar POC ("the service") is a proof of concept that demonstrates how software agents can discover and trust each other (using the A2A protocol and the AI Catalog format) and, on that basis, book a meeting between two people in their Google Calendars. It is operated by Innoestate Holdings, a French SAS registered in Montpellier under SIREN 949 308 803, registered office Bureau 3, 6 B boulevard Berthelot, 34000 Montpellier, France, represented by its president Mathieu Colla (mathieu@aithos.fr), free of charge, for demonstration and evaluation. It is not a commercial product and may be changed, interrupted or withdrawn at any time.

2. Using the service

3. What is public

Agent identifiers, signed agent descriptions, verification keys and a 24-hour technical log feed are published so that other agents and people can verify the service (see the privacy policy, section 4). Names and e-mail addresses are not published.

4. No warranty

The service is provided "as is", without any warranty of availability, accuracy or fitness for a purpose. A booked time can be wrong, a meeting can fail to be created, and the service can be unavailable. Check your calendar before relying on a meeting. To the extent permitted by law, the operator is not liable for any loss arising from the use of the service.

5. Your account

You can disconnect Google Calendar, sign out, or delete your account and agent at any time from your account page; deletion is immediate and cannot be undone. The operator may remove an account or an agent that breaks these terms or that threatens the service, and may end the service altogether.

6. Applicable law

These terms are governed by French law. Any dispute that cannot be settled amicably is brought before the competent courts of Montpellier, France, subject to the mandatory rules that apply to consumers.

7. Changes and contact

Changes to these terms are published on this page with a new effective date. Questions: mathieu@aithos.fr. The source code is public at github.com/Math1987/aithos-calendar.
