50M+ websites requiring age-gated compliance globally
The Problem

Governments worldwide are rapidly mandating strict age verification on websites and platforms, rendering simple self-attestation illegal. The current alternatives—uploading passports, government IDs, or biometric face scans to third-party databases—create massive privacy risks, frequent data breaches, and a de facto surveillance infrastructure that users and platforms alike find unacceptable.

Potential Solution

A drop-in API gateway that lets websites verify a visitor's age using zero-knowledge cryptographic proofs. Users complete a one-time identity verification through a trusted credential issuer, then receive a reusable cryptographic token that proves only 'this person is 18+' without revealing name, face, or ID number. Platforms integrate a lightweight SDK and never touch or store personal data, eliminating breach liability while satisfying regulatory requirements.

Why Now?

A wave of enforceable age-verification laws—the UK Online Safety Act, the US Kids Online Safety Act (HR 7757), and similar EU and Australian mandates—are creating immediate legal obligations for millions of websites. Platforms face compliance deadlines with no privacy-respecting solution available at scale, making this an urgent infrastructure need.

Launch
Jul 20, 2026

AgeCheck API lets developers verify whether a user meets an age requirement using trusted national digital wallets. Instead of collecting IDs or personal data, your app receives a simple boolean response, making integration privacy-first and compliance-friendly. REST API, developer-first documentation, 1,000 free verifications, then €0.10 per check.. Product Hunt launch with 4 votes and 3 comments.

Comment on AgeCheck API
Jul 20, 2026

Hi Product Hunt! 👋 I’m the founder of AgeCheckAPI.com The idea came from a simple observation: most age verification solutions collect far more personal data than they actually need. In many cases, an application or website needs to know only one thing: is the user old enough? It doesn’t need their name, date of birth, or a copy of their ID. At the same time, Europe is rolling out trusted national digital identity wallets. We saw an opportunity to build an API that leverages this new infrastructure while keeping privacy at the center. Our goal was to make integration as simple as any modern REST API. Developers shouldn’t have to become identity experts or deal with complex verification flows. They should be able to add age verification in minutes and receive a simple boolean response. Building the first version meant balancing security, compliance, and developer experience. We spent a lot of time simplifying the API, improving the documentation, and reducing the amount of code required for integration. We’re excited to hear your feedback and learn what features would make AgeCheck API even more useful for your applications. Thanks for checking it out!
