# Verification

This section covers how to integrate XION's verification infrastructure (the Truth Engine) into your application. Whether you are building a consumer app that needs to verify user identity, an advertising platform that needs to confirm real humans, or a DeFi protocol that needs to assess creditworthiness, these guides walk you through the full integration.
