Age verification as a service: wallet-native "over 18" for any platform, via an intermediary layer
by espuni
Online platforms must verify users are over 18 to comply with DSA Article 28 and national law — but the traditional route forces users to expose their identity to prove a single fact, and building a wallet-native verifier in-house is out of reach for most businesses. espuni is an independent intermediary layer that provides age verification as a service on top of EUDIPLO (OWF). Instead of each platform building and maintaining its own EUDI verifier, any service integrates once and lets espuni handle the wallet interaction, the trust-list validation, and the protocol complexity. The user presents a proof-of-age credential from their EUDI Wallet; espuni requests only the "over 18" attribute, validates the issuer against the EU Age Verification Trusted List, and returns a yes/no. No name, no birthdate, no document reaches the platform. Built on open standards (OID4VP, ISO 18013-7) and open source, it supports the Digital Credentials API with QR fallback, and works across EUDI wallets. The intermediary model is what makes wallet-native age verification realistic for the small and mid-sized businesses that can't build it themselves — a practical on-ramp to the EUDI ecosystem.

How it works
1 - A platform with an age-verification obligation (a shop, a streaming service, a gambling operator) integrates espuni once — a single integration instead of building an EUDI verifier from scratch.
2 - A user reaches age-restricted content. Instead of uploading a document, they're offered "Verify with your EUDI Wallet."
3 - espuni sends a presentation request for the age_over_18 attribute only — via the Digital Credentials API by default, but falling back to QR code if DC API is not available or rejected by the user.
4 - The user's EUDI Wallet shows exactly what's being requested — only "over 18," nothing else — and the user approves.
espuni receives the response, validates the issuer against the EU Age Verification Trusted List, and verifies the proof.
5 - The platform receives a verified yes/no. It never sees the user's identity, and the wallet interaction, trust validation, and protocol handling all happened in the intermediary layer — invisible to both the platform and the user.
The platform gets compliance without building or maintaining identity infrastructure; the user proves age without exposing identity; the exchange leaves an auditable cryptographic record.
