What is Tessio?

Tessio is an age and identity verification API built on the EU Digital Identity Wallet.

Most age assurance today means uploading an ID document or taking a selfie. That solves the regulator's problem by creating a data protection one, because you then hold identity data you have to secure, justify and disclose if it leaks.

Tessio asks a narrower question. One API call starts an over 18 check, the user approves it in their wallet, and a signed result lands on your webhook. The credential we request is the EU age verification attestation, which contains thirteen age booleans and nothing else. There is nothing to store, because there is nothing to receive.

Built for platforms that need to meet the UK Online Safety Act and the EU Digital Services Act without becoming a custodian of identity data. The verifier underneath is open source .NET, Apache-2.0, on NuGet, so you can self host it or read exactly what it does.

Member states must make the wallet available by December 2026 under Regulation (EU) 2024/1183, and regulated relying parties must accept it by December 2027.

The API is live and you can integrate against the sandbox today. Access is invite only. Production wallets require a relying party access certificate, which we have applied for and do not yet hold, as is true of every relying party in Europe right now.
