Tesera

Passport control for AI agents

Only verified agents get through.

AI agents now book tables, reserve appointments and pay on people's behalf. We verify every agent, and the person behind it, before it reaches your business. Unverified agents are sent to us first.

How it works

Four steps, on every booking, payment and request.

  1. 01

    Verify

    An agent signs up once, together with the person it acts for. It gets a passport.

  2. 02

    Set rules

    People decide what their agent may do. Businesses decide what they accept.

  3. 03

    Request

    Every booking, payment or request goes through Tesera first.

  4. 04

    Pass or block

    Within the rules: handed to the other agent.

    Outside the rules: blocked.

No passport? Unverified agents are redirected to verify before they can do anything.

53%

of web traffic is already automated. Agents are at your door today.

Imperva, Bad Bot Report 2026

“The bottleneck for the agent economy is shifting from intelligence to identity.”

Card networks check agents when a card is charged. A table, an appointment, a request: nobody checks. Until now.

We asked people to draw trust.

Twenty drawings. Eight show family. Not one shows a password.

  1. Two overlapping circles labelled Mom and Me. The overlap says Trust; arrows point to it from the words Love and Vulnerability.

  2. Two stick figures hold a bow and arrow between them, one drawing the string, the other holding the bow. A speech bubble says: I trust you.

“Trust = know where it comes from & where it goes.”

Drawing Nº 08

That is what we check on every agent: the person it comes from, and where it is allowed to go.
