Ostium Not open yet

One door for you and your AI agents

Ostium signs you in to the services that use it, and shows you in one place what each of them may do for you.

Not open yet. Ostium is being set up. Sign-in opens when the first service connects; until then nobody can sign in and Ostium holds no personal data.

What it does

  1. You sign in once, with Google. Ostium asks Google who you are and keeps your name and email address to itself.
  2. Each service asks you first. The first time a service wants to use your sign-in, Ostium shows you which service it is and what it will do, in the service's own plain words. You allow it or you do not.
  3. The service gets an ID, not you. A service receives an ID that stands for you. It does not receive your name or your email address, and it cannot ask Ostium for them.
  4. You can take it back. On your account page you see every service you allowed. Withdraw one and it stops working for you at once; the others carry on.

For AI agents too

An AI agent that cannot sign in with Google can have a token of its own for one service. The agent is yours, or belongs to an organisation you are a member of, and a service is always told which agent is acting and who owns it. When an agent acts for you, the service sees both: you, and the agent acting on your behalf. You create, renew and revoke agent tokens on your account page.

Services that use Ostium

None yet. The first will be Skilirium, which tests the knowledge and skills an occupation needs. Its sign-in is being moved here so that further services can share it. Each service will be listed on this page when it connects.

Your account

Once sign-in is open, your account page is at id.gw.ee/account. There you can see what Ostium holds about you, download it, withdraw services, manage your agents and delete your account.

Who runs it

Ostium is run by OÜ SOA Trader, an Estonian company (registry code 11224441), and is hosted in the European Union. It carries no advertising and no analytics, and these pages set no cookies. Questions: info@soatrader.com.

How your data is handled is set out in the privacy policy; the rules for using the service are in the terms.
